It’s all about the right balance


Collaborative work of research groups at the University of Würzburg and the TU Dresden has provided important new insights for cancer research. During cell division specific target proteins have to be turned over in a precisely regulated manner. To this end specialized enzymes label the target proteins with signaling molecules. However, the enzymes involved in this process can also label themselves, thus initiating their own degradation. In a multidisciplinary approach, the researchers identified a mechanism of how enzymes can protect themselves from such self-destruction and maintain sufficient concentrations in the cell. These results have been published in the latest issue of Science Signaling.

Vital functions of the multicellular organisms, such as growth, development, and tissue regeneration, depend on the precisely controlled division of cells. A failure in the underlying control mechanisms can lead to cancer. A team of researchers led by Dr. Sonja Lorenz from the Rudolf Virchow Center - Center for Integrative and Translational Bioimaging at the University of Würzburg and by Dr. Jörg Mansfeld from the Biotechnology Center (BIOTEC) at the Technical University of Dresden discovered a new mechanism that modulates cell division.

Ubiquitination – a central regulatory element
A critical step in cell division is the distribution of the genetic information evenly between the daughter cells. This process is controlled by a large protein complex, the anaphase-promoting complex/cyclosome (APC/C), which labels proteins with a signaling molecule known as “ubiquitin”. The ubiquitin label functions essentially as a molecular postal code, targeting labeled proteins to the cellular protein degradation machinery. To allow for the efficient and precise labeling of target proteins, the APC/C works together with an ubiquitin-conjugating enzyme, UBE2S. However, UBE2S also has the ability to modify itself with ubiquitin, thus initiating its own degradation. This ability applies to ubiquitination enzymes in general. “This raises the fundamental question of how ubiquitination enzymes find the right balance between labeling their targets and labeling themselves to ensure that sufficient quantities of the enzymes are available in the cell,” says Sonja Lorenz.

Switching between active and inactive states
The new study provides an answer to this question by showing that UBE2S can adopt an inactive state in which it is unable to label itself with ubiquitin. "When UBE2S forms a dimer, i.e., two molecules pair with each other, they become inactive and protected from self-destruction," says Jörg Mansfeld. The scientists suggest that this mechanism ensures that a stable cellular pool of UBE2S is preserved and re-activated when required. The cell can thus control the ratio of active and inactive UBE2S to fine tune cell division. These findings provide a structural framework for the development of new cancer-therapeutic strategies and drug discovery.

Ubiquitin research in the Lorenz and Mansfeld groups
The current study presents the second successful, published collaboration of the Lorenz and Mansfeld groups on the regulation of UBE2S. Notably, both research articles were featured in dedicated commentary pieces.

The research group of Sonja Lorenz investigates the structural basis of the ubiquitin system, which controls almost all cellular processes. She is particularly interested in revealing the factors that account for the enormous specificity of ubiquitin as a molecular signal. Her group combines high-resolution structural techniques that yield atomic-resolution views with biochemical, biophysical, and cell-based methods. The Lorenz laboratory is funded by the Emmy Noether program of the German Research Foundation (DFG) and an ubiquitin-focused Research Training Group (GRK2243; DFG), which Sonja Lorenz represents as a co-speaker. Sonja Lorenz is also a founding member of the Mildred Scheel Early Career Center (German Cancer Aid) in Würzburg and has been engaged with transregional ubiquitin initiatives. In 2018 Dr. Lorenz was accepted into the highly selective EMBO Young Investigator Program. A member of the Lorenz laboratory, Anna Liess was part of the Würzburg Graduate School of Life Sciences and the GRK2243 and successfully defended her PhD thesis in 2020.

Jörg Mansfeld and his research group focus on ubiquitination and other protein modifications. The Mansfeld group uses cell biology and biochemical methods to investigate the role of these modifications in the decision whether a cell continues to divide or stops, in order to fulfill a specialized function. The Mansfeld group is funded by the ERC under the European Union’s Horizon 2020 research and Innovation Program as well as Emmy Noether and project grants of the DFG. Alena Kučerová is a PhD student of the Dresden International Graduate School for Biomedicine and Bioengineering (DIGS-BB) and was supported by a DIGS-BB Fellowship.

Engineers link brains to computers using 3D printed implants


Linking the human brain to a computer is usually only seen in science fiction, but now an international team of engineers and neuroscientists at the University of Sheffield (UK), St Petersburg State University (Russia) and Technische Universität Dresden (Germany) have harnessed the power of 3D printing to bring the technology one step closer to reality.

In a new study published in Nature Biomedical Engineering, the team led by Professor Ivan Minev (BIOTEC, TU Dresden alumni now at the Department of Automatic Control and Systems Engineering, Sheffield) and Professor Pavel Musienko (St Petersburg State University), have developed a prototype neural implant that could be used to develop treatments for problems in the nervous system.

The neural implant has been used to stimulate the spinal cord of animal models with spinal cord injuries and now could be used to develop new treatments for human patients with paralysis. The proof of concept technology has been shown in the study to also fit well on the surface of a brain, spinal cord, peripheral nerves and muscles, hence opening possibilities in other neurological conditions.

Linking the human brain to a computer via a neural interface is an ambition for many researchers throughout the worlds of science, technology and medicine, with recent stories in the media highlighting efforts to develop the technology. However, innovation in the field is hampered by the huge costs and long development time it takes to produce prototypes - which are needed for exploring new treatments.

The technology promises great potential to bring new medical treatments for injuries to the nervous system based on a fusion of biology and electronics. The vision relies on implants that can sense and supply tiny electrical impulses in the brain and the nervous system.

The team has shown how 3D printing can be used to make prototype implants much quicker and in a more cost effective way in order to speed up research and development in the area. The implants can be easily adapted to target specific areas or problems within the nervous system.

Using the new technique, a neuroscientist can order a design which the engineering team can transform into a computer model which feeds instructions to the printer. The printer then applies a palette of biocompatible, mechanically soft materials to realize the design. The implant can be quickly amended if changes are required, giving neuroscientists a quicker and cheaper way to test their ideas for potential treatments.

Ivan Minev, BIOTEC, TU Dresden alumni, now Professor of Intelligent Healthcare Technologies at the University of Sheffield’s Department of Automatic Control and Systems Engineering, said: “The research we have started at TU Dresden and continuing here at Sheffield has demonstrated how 3D printing can be harnessed to produce prototype implants at a speed and cost that hasn’t been done before, all whilst maintaining the standards needed to develop a useful device. The power of 3D printing means the prototype implants can be quickly changed and reproduced again as needed to help drive forward research and innovation in neural interfaces.”

The researchers have shown that 3D printers can produce implants that can communicate with brains and nerves. Following this early work, the team aims to demonstrate how the devices are robust when implanted for long periods of time.

The team’s ambition, however, is to go to the clinic and open up the possibilities of personalized medicine to neurosurgeons.

Professor Minev added: “Patients have different anatomies and the implant has to be adapted to this and their particular clinical need. Maybe in the future the implant will be printed directly in the operating theatre while the patient is being prepared for surgery.”

How do tumor cells divide in the crowd?


Scientists led by Dr. Elisabeth Fischer-Friedrich, group leader at the Excellence Cluster Physics of Life (PoL) and the Biotechnology Center TU Dresden (BIOTEC) studied how cancer cells are able to divide in a crowded tumor tissue and connected it to the hallmark of cancer progression and metastasis, the epithelial-mesenchymal transition (EMT).

Most animal cells need to become spherical in order to divide. To achieve this round shape, the cells must round up and deform their neighboring cells. In a growing tumor tissue, the tumor cells need to divide in an environment that is becoming more crowded than the healthy tissue. This means that the dividing tumor cells likely need to generate much higher mechanical forces to round up in such a densely packed surrounding. Yet, tumor cells seem to be adapted to overcome these difficulties. Scientists led by Dr. Elisabeth Fischer-Friedrich were curious how do the tumor cells gain this enhanced ability to deal with the crowded tumor environment?

The researchers found that the EMT could be one of the answers. What is it exactly? “EMT or epithelial-mesenchymal transition is a hallmark of cancer progression,” says Kamran Hosseini, PhD student who performed the experiments. It is a cell transformation during which tumor cells lose their asymmetric organization and detach from their neighbors, gaining the ability to migrate into other tissues. This, together with other factors, allows tumors to metastasize, i.e., move into the blood and lymphatic vessels and ultimately colonize other organs.

“So far, EMT has been mainly linked to this enhanced cell dissociation and cell migration. Our results suggest that EMT might also influence cancer cells by promoting successful rounding and cell division. These results point towards a completely new direction of how EMT could promote metastasis of carcinoma in the body,” explains Kamran Hosseini.

Just as we test the ripeness of the fruits by squeezing them gently with our hands, the scientists examined the mechanical properties of individual human cells. Except, they squished the cells using an atomic force microscope. This state-of-the-art setup measured properties such as cell stiffness and cell surface tension before and after the EMT. In addition, the group of Dr. Elisabeth Fischer-Friedrich in collaboration with Dr. Anna Taubenberger (BIOTEC, TU Dresden) and Prof. Carsten Werner (IPF, Dresden) cultured mini-tumors and trapped them inside elastic hydrogels to check how mechanical confinement affects cell rounding and division of tumor cells.

The authors identified changes in rounding and growth of the tumor. EMT influenced the cancer cells in two contrasting ways. The dividing tumor cells became stiffer while surrounding non-dividing cells became softer. Furthermore, the researchers found hints that the observed mechanical changes could be linked to the increased activity of a protein called Rac1, a known regulator of the cytoskeleton.

“Our findings will not only provide important results to the field of cell biology but may also identify new targets for cancer therapeutics,” says Dr. Elisabeth Fischer-Friedrich.

This study was founded by the German Research Foundation (DFG) and performed in collaboration with the Light Microscopy Facility (LMF) of the CMCB Technology Platform at TU Dresden.

Looking for a needle in a haystack: TU Dresden's BIOTEC and its PharmAI spin-off analyse millions of active substances that could cure Covid-19


The goal: Identify new drugs for Covid-19 therapy in the fastest possible way, conduct clinical tests and win the battle against the virus.

The method: A large-scale research competition that screens billions of molecules in order to find those blocking interactions on SARS-CoV-2, identifying those that can be used therapeutically very quickly thanks to their existing FDA-approval. 

The Biotechnology Center (BIOTEC) of TU Dresden with its bioinformatics group and the spin-off PharmAI GmbH participate in such a competition – the so-called JEDI Grand Challenge. Until tomorrow, proposals for active substances that have the potential to stop the activity and reproduction of the virus can be submitted. The Dresden team led by Prof. Michael Schroeder (BIOTEC) and Dr. Joachim Haupt (PharmAI) used proprietary screening algorithms to screen several drug libraries containing five million substances for candidates against Covid-19. They submitted three promising protein targets to The Joint European Disruptive Initiative (JEDI).

"For more than ten years, we have been developing new screening algorithms for protein structures at BIOTEC. We are looking for hidden information of protein molecules, e.g. remotely similar binding sites across evolutionary unrelated target proteins, where active compounds can dock to like a puzzle. In this way, we aim to identify new therapeutic applications for known substances, using approved drugs for new or other diseases. We are pleased that our DiscoveryEngine has also been successful with Covid-19 and that we can now make good drug candidates available to the global scientific community via the competition – following the spirit of Open Science. Through the collective knowledge of virologists, molecular biologists and bioinformatics scientists, high-throughput screening and artificial intelligence, we help from Dresden to ensure that curative drug cocktails with few side effects are found quickly," explains Prof. Michael Schroeder. 

The DiscoveryEngine developed at BIOTEC is a virtual screening software that has been optimised over the years and which, depending on the target, e.g. cancer, identifies those molecules that have suitable structures to act against the disease. The DiscoveryEngine was the basis for the spin-off of PharmAI from BIOTEC. "With that, we enable a broad clinical and economic use of our method. And the competition, in which we are involved as BIOTEC partners, is a great opportunity to show our potential," says Dr. Joachim Haupt, CEO of PharmAI and former postdoc at BIOTEC. "The DiscoveryEngine is fast and accurate. In just one week we have screened five million small molecules. Conventional computer-based methods would take about ten years of computation time to complete the task at a rate of only one minute per substance. Our hit rate was also significantly higher than with conventional screening methods. This speed and targeting are exactly what is required in the fight against Covid-19." 

"We are very pleased to have received the submission of TU Dresden and PharmAI. It is part of a tremendous response we got from over 100 international teams. In autumn, after experimental validation, we will know which of the predicted drugs may bring us a step closer towards combatting the virus", says Prof. Thomas M. Hermans, Program Manager at JEDI. 

In stages two and three of the JEDI Grand Challenge, the collective knowledge of the participating international virologists will be used to analyse the promising substances submitted and to quickly identify protein compounds from them that can completely eliminate the virus. By using high-throughput virus testing, new drug combinations with minimal toxicity and virtually no side effects are to be found, which will then be rapidly tested in clinical trials and could soon cure Covid-19 patients. Prof. Michael Schroeder: "Then, the search for the needle in the haystack would have been successful in record time. We are eagerly awaiting the results."

What can liner shipping learn from brain network science?


Team of researchers from Germany and China unveils how the organization of global maritime transport networks impacts economy by using methods from brain network analysis.

Dr. Carlo Vittorio Cannistraci from TU Dresden’s Biotechnology Center (BIOTEC) is focusing his research on network science applied to biological systems and neuroscience. At the Biomedical Cybernetics lab, he lead an translational study showing how network science computational theories effective for brain analysis can help to understand global shipping networks and their impact on world economy. The study was conducted together with maritime economy scientists from China, and has now been published in the scientific journal Nature Communications.

Around 80 per cent of global trade by volume is transported by sea, and thus the connectivity network of the maritime transportation system is fundamental to the world economy and the functionality of its society. To better exploit new international shipping routes, the current ones need to be analysed: What are the principles behind their network organization? What mechanisms determine the complex system association with international trade? However, there is another complex system that, similarly to maritime transportation systems, links the navigability of its network structure and organization to its efficient performance in the environment. This complex system is: the brain. The motivation for this comparative and trans-disciplinary research came from the exchange during an international network science conference, followed by three years of collaborative work on the topic.

"Many complex systems share basic rules of self-organization and economical functionality. When I examined the maritime network structure of the Chinese colleagues at the conference, I advanced the hypothesis that its structure displays a trade-off between high transportation efficiency and low wiring cost, similarly to the one we know is present in brain networks. We combined our knowledge in network science, maritime science and data processing, which led to new insights into the maritime network structural organization complexity and its relevance to international trade", explains Dr. Cannistraci, research group leader for biomedical cybernetics at BIOTEC, TU Dresden. "An important result of this study is the development of new computational network measures for investigation of modular connectivity and structural core organization within complex networks in general, which here we applied to maritime science. In future projects I plan to use these newly developed methods in my research at the BIOTEC where I focus on computational and network systems in biomedicine. They might return particularly useful for brain network organization analysis and the development of markers for brain diseases, such as depression and Alzheimer.”

The study was conducted in collaboration with Dr. Mengqiao Xu, M.S. Qian Pan and Dr. Haoxiang Xia from the Dalian University of Technology (China) and Dr. Alessandro Muscoloni from the Biomedical Cybernetics lab at BIOTEC, TU Dresden (Germany). It was funded by an Independent Group Leader Starting Grant for Carlo Vittorio Cannistraci from BIOTEC and by the Tsinghua Laboratory of Brain and Intelligence, Tsinghua University, Beijing (China). The study was supported by Alphaliner S.A.R.L. (France), which provided comprehensive data on global liner shipping.

Who takes the temperature in our cells? - Baker's yeast cells provide information on how organisms could cope with global warming and other altered environmental factors


The conditions in the environment are subject to large fluctuations. In Germany, for instance, temperatures can range from a freezing minus 20 degrees Celsius in the winter to a hot 40 degrees Celsius in the summer. Organisms that are unable to adapt to such temperature changes will not survive and thus will not pass on their genetic information to the next generation. In a world in which we are confronted with constantly rising average temperatures due to global warming, we must ask ourselves: How do organisms react to changing temperatures? What molecular mechanisms do they use?

Decades of research have shown that different organisms respond very similarly to temperature changes. When organisms are exposed to heat, their cells cease to grow, they shut down the production of housekeeping proteins that are required for growth and reproduction. Instead, they start to produce proteins that protect the cells from heat-related damage. In other words, the cell factory changes its protein production. However, it is not known how cells recognize heat stress and which mechanisms trigger the production change.

Baker's yeast as model organism

Scientists at the Biotechnology Center (BIOTEC) of the TU Dresden and the Max Planck Institute for Molecular Cell Biology and Genetics (MPI-CBG), together with partners in Heidelberg and Toronto, Canada, investigated these fundamental questions. They used a popular model organism in cell research: baker’s yeast as we know it from baking bread or brewing beer. This single-celled organism provides us with insights into the basic processes of life because it has almost the same composition as human and animal cells. If we understand the molecular processes within the yeast cell, we can also better understand the development of diseases in complex organisms such as humans.

"In yeast, we were able to identify one critical protein, Ded1p, which changes its structure upon heat stress and then reprograms the cell machinery. In the laboratory, we simulated the behavior of Ded1p with purified components and observed the following: Under normal conditions, Ded1p is evenly distributed in the cytoplasm of cells, but when the temperature rises, it assembles into dense structures, using the process of phase separation," explains Christiane Iserman, the lead author of the study. "The fact that Ded1p is able to sense temperature suggests that this protein is a kind of thermometer inside the cell."

Furthermore, the scientists have investigated the consequences for the cell when Ded1p forms these dense structures. "They are telling the cell to downregulate the production of housekeeping proteins, and to ensure that the production of stress-protective proteins is upregulated," explains Chrisitine Desroches Altamirano, second author of the study.

Results may help to better understand neurodegenerative diseases

This very elegant mechanism does not seem to be limited to baker’s yeast. The researchers found that the Ded1p proteins from other organisms are well adapted to the temperature of the respective habitat. "This suggests that evolution has endowed our cells with a high thermal sensitivity so that living organisms can adapt to temperature fluctuations. This gives us hope that organisms will be able to cope with global warming," explains Prof. Simon Alberti, who led the study.

Alberti: “However, our discovery may have an even more general relevance: We have discovered a mechanism within the cell that helps the organism to deal with a variety of changes in the environment, not just heat stress. Cells seem to be able to deal with a wide variety of environmental signals by using proteins that phase separate to run different gene expression programs. In further studies, we want to determine whether this mechanism can help us understand human diseases - primarily those in which our cells do not process certain stress situations properly, as it appears to be the case in age-related neurodegenerative diseases".

The research project was initiated in 2015 and led by the Alberti research group at BIOTEC. The close collaboration of 19 scientists from the TU Dresden, the MPI-CBG in Dresden, the University of Heidelberg, the European Molecular Biology Laboratory in Heidelberg and the University of Toronto in Canada was central to the success of the project. The research project was funded by the Max Planck Society, TU Dresden, the Max SynBio Consortium, the European Research Council (ERC), the Human Frontiers Science Program (HFSP), the Volkswagen Foundation and the Boehringer Ingelheim Fund. The research results were published in the renowned scientific journal Cell.

The Ded1p protein of baker's yeast changes from a diffuse state (unstressed green cells, left) to a state in which it forms dense structures (heat-stressed green cells, right). The transition is caused by the process of phase separation and is triggered by an increase in ambient temperature. The Ded1p protein was genetically labeled with a green fluorescent dye.

How do our cells respond to stress? - Molecular biologists reverse-engineer a complex cellular structure that is associated with neurodegenerative diseases such as ALS


Cells are often exposed to stressful conditions that can be life threatening, such as high temperatures or toxins. Fortunately, our cells are masters of stress management with a powerful response program: they cease to grow, produce stress-protective factors, and form large structures, which are called stress granules. Scientists at the Biotechnology Center (BIOTEC) of the TU Dresden and the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG), together with partners in Heidelberg and St. Louis (USA) have investigated how these mysterious structures assemble and dissolve, and what may cause their transition into a pathological state as observed in neurodegenerative diseases such as ALS (amyotrophic lateral sclerosis). Their results were published in the renowned scientific journal Cell.

ALS is a hitherto incurable disease of the central nervous system in which the motor neurons – nerve cells responsible for the muscles movement – gradually die. Do stress granules play a role in this process?

Stress granules are formed in the cytoplasm of the cell and assemble from a large number of macromolecular components such as messenger RNAs and RNA-binding proteins. Stress granules usually disassemble when the stress subsides, a process which is promoted by the dynamic nature of stress granules. However, a hallmark of ALS is the presence of non-dynamic, persistent forms of stress granules.

"In ALS, patients suffer from muscle weakness and paralysis. Stress granule-containing motor neurons slowly degenerate, causing a progressive loss of motor functions. We need to better understand the complex biology of stress granules in order to design and develop future therapeutic strategies that counteract the course of the disease. But the complex environment of the cells within an organism makes this difficult," explains Dr. Titus Franzmann, one of the senior authors of the publication.

In order to systematically test their hypotheses about the assembly of stress granules and the pathology causing molecular changes, the scientists developed a controlled environment using an in vitro system with purified components that allowed the recreation of stress granules in a test tube. They observed stress granule assembly step by step and characterized the critical factors underlying their dynamics.

"Stress granules have a very complex structure. Nevertheless, their formation depends primarily on the behavior of a single protein - the RNA-binding protein G3BP," says Dr. Jordina Guillén-Boixet, one of the first authors of the study. "This protein undergoes a critical structural change: Under non-stress conditions G3BP adopts a compact state that does not allow stress granules to assemble. But under stress, RNA molecules bind to G3BP allowing multiple interactions that promote the assembly of dynamic stress granules. The subsequent transition from dynamic into non-dynamic state, which may be caused for example by prolonged stress, may trigger the death of the motor neurons, as we can observe in the disease ALS.”

The research project was initiated in 2015 and led by the Alberti research grout at TU Dresden´s BIOTEC. The close co-operation of 23 scientists from the TU Dresden, the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, the European Molecular Biology Laboratory in Heidelberg and the Washington University in St. Louis (USA) was central for the success of the project. Prof. Simon Alberti: "There is a number of remaining questions. Our experimental system at BIOTEC is now available for further testing and will be central to developing new diagnostics and therapeutics to combat neurodegenerative diseases such as ALS."

The research project was funded by the European Research Council (ERC), the Human Frontiers Science Program (HFSP), the European Molecular Biology Organization (EMBO), the German Research Foundation (DFG), the Federal Ministry of Education and Research (BMBF) and the Joint Neurodegenerative Disease Research Program (JPND) of the EU.

TU Dresden team presents DipGene at Synthetic Biology’s largest innovation event


The student project DipGene developed a new methodology that makes genetic testing as easy as a pH-test. With their simple, cheap and low-tech method to test for the presence of any DNA sequence, they won a prestigious Gold Medal.

A student team of the TU Dresden successfully showcased their DipGene project at the annual iGEM Giant Jamboree, the synthetic biology’s largest innovation event, which is hosted by the International Genetically Engineered Machine (iGEM) Foundation. The Giant Jamboree is the culminating event of iGEM’s annual, worldwide, synthetic biology competition for students to use genetic engineering to solve local problems all around the world. The TU Dresden team was able to win a Gold Medal for their overall achievements.

Each year, the competition brings together more than 6,000 participants from across the globe to explore and create unique applications of synthetic biology with the mission to bring positive contributions to their communities and society at large. Beyond the technology, participants are evaluated on teamwork, responsibility, entrepreneurship, sharing, safety and more.

This year’s TU Dresden team consisted entirely of team members from two masters’ programs of the Center for Molecular and Cellular Bioengineering (CMCB), with nine members from seven different countries, namely India, Spain, Russia, Germany, Iran, Colombia and Ecuador. With DipGene, they focused on the development of a DNA sequence-specific diagnostic method that is applicable in the field. They could show that their method can be applied for bacteria, as well as human genomic DNA, for example for the detection of predisposition to monogenic diseases. For application in bacteria no amplification is needed, the method only takes five to ten minutes and is therefore much faster and cheaper than commonly used laboratory techniques, like polymerase chain reaction (PCR) followed by gel electrophoresis. It could be used in the lab during genetic manipulation of bacteria, to faster verify correct clones. In future research they hope to overcome the need for an amplification step by extracting genomic DNA from blood rather than by buccal swap. This way their method could be applied anywhere by anyone without the need for laboratory equipment.

“This year’s Giant Jamboree was a spectacular display of hard work and ingenuity. These students are showing the world what’s possible when we fearlessly tackle tough problems and open our minds to new applications of engineering biology,” said Randy Rettberg, co-founder and president of iGEM. “Many of the projects presented at iGEM will serve as the foundation and inspiration for important research, influential companies and international interest to come – these participants are most certainly tomorrow’s leaders.”

The three supervisors from the CMCB and the Faculty of Biology Dr. Frank Groß, Prof. Thorsten Mascher and Philipp Popp are very excited about the spirit and the success of the team. “Developing novel scientific ideas from scratch and having to go through each and every process of project development shapes young scientists tremendously – this opportunity in the frame work of the iGEM competition makes it a unique experience for everyone involved,” said Philipp Popp, who participated in iGEM himself in 2014 and already supervised the 2017 team of the TU Dresden.

Obesity risk quantification: a jump towards the future through the lens of artificial intelligence applied to lipid science


According to WHO, nearly 1 out of 6 adults is obese. This makes obesity a prime threat to human health because it increases mortality and morbidity. In daily healthcare practice, the go-to indicator of overweight and obesity is the body mass index (BMI), a calculated relation between body weight and height. An international team of scientists led by Dresden researchers, with a joint effort between academy and industry in Saxony (Germany) introduces a revolutionary approach towards personalized and precision biomedicine. The discovery is that artificial intelligence can assist to design markers composed of a small combination of lipids that allow to provide significantly more information about obesity than BMI.

When academy meets industry significant jumps towards the future are possible. Researchers from the Biotechnology Center (BIOTEC) at the TU Dresden and Lipotype GmbH, a spin-off of the Max Planck Institute for Molecular Cell Biology and Genetics, Dresden, with the international participation of scientists from Lund University (Sweden) and National Institute for Health and Welfare (Finland) teamed up to critically investigate the BMI of more than 1000 patients. The international research team applied advanced artificial intelligence tools to develop an algorithm which makes use of the human blood plasma lipid composition, the plasma lipidome.

The plasma lipidome contains hundreds of distinct lipids. “Together, they are valuable indicators to explore the state of metabolism health of an individual - like a health fingerprint”, explains Mathias Gerl from Lipotype. This lipidomic data was used for training the algorithm to predict the BMI of each patient.

In comparison to the ‘household measures’-based BMI (observed BMI), the lipidomic data provided the new algorithm with the power to propose a new ‘molecular lipidomic BMI’ (predicted BMI). The lipidomic BMI calculation revealed that the molecular BMI was in a number of cases significantly higher than the traditional BMI. In approximately 1 out of 7 patients, the lipidomic BMI improved the classic ‘morphometric BMI’, and provided more information about obesity compared to the traditional BMI measurement, e.g. about the amount of visceral fat, a harmful kind of fat deposit.

“Long-time consequences can occur when a patient in need for a weight reducing therapy to combat the risk for obesity-associated disease is sent home without remedy”, states Olle Melander from Lund University. “These patients may suddenly suffer from a heart attack at age 40 leaving their doctors puzzled”, comments Carlo Vittorio Cannistraci from BIOTEC at the TU Dresden and adds: “We should overcome the obsolete logic that a single marker can help to assess risk in complex systems such as humans. Computational biomedicine adopts artificial intelligence to design multidimensional markers composed of many variables that increase precision of diagnosis. Hence, we hope that the traditional BMI will be replaced with a lipidomic marker to outpace the misclassification of 14% of patients.”

A new method of tooth repair? Scientists uncover mechanisms that could help future dental treatment


Researchers from TU Dresden’s Biotechnology Center teamed up with international scientists that led to the discovery of a new stem cell population in the front teeth of mice

Stem cells hold the key for tissue engineering, as they develop into specialised cell types throughout the body including in teeth. An international team of researchers, including scientists from the Biotechnology Center of the TU Dresden (BIOTEC), has found a new mechanism that could offer a potential new solution to tooth repair. They discovered a new population of mesenchymal stromal cells in a continuously growing mouse incisor model. They have shown that these cells contribute to the formation of dentin, the hard tissue that covers the main body of a tooth. Importantly, the work showed that when these stem cells are activated, they send signals back to the mother cells of the tissue to control the number of cells produced, through a molecular gene called Dlk1. This study is the first to show that Dlk1 is vital for this process to work. In the same study, the researchers also demonstrated that Dlk1 can enhance stem cell activation and tissue regeneration in a wound healing model. This mechanism could provide an innovative solution for tooth repair, addressing problems such as tooth decay, crumbling and trauma treatment. Further studies are needed to validate the results for clinical applications to determine the appropriate duration and dose of treatment.

The study was led by Dr Bing Hu of the Peninsula Dental School of the University of Plymouth, UK. Co-authors were research group leader Dr. Denis Corbeil and his colleague Dr. Jana Karbanová from BIOTEC. "The discovery of this new population of stromal cells was very exciting and has enormous potential in regenerative medicine," says Dr. Denis Corbeil.

A new force awakens


Newly discovered physical force contributes to proper development of the red flour beetle Everyone’s life has its milestones.

Lewis Wolpert, a British developmental biologist, once said that it is not birth, marriage or death but gastrulation that is the most important event in life. Gastrulation describes the process during which the single-layered blastula (a hollow sphere of cells) is reorganized into a multilayered structure known as the gastrula. In the process, physical forces reshape the embryonic tissue to form complex body plans of multicellular organisms. In many embryos, the gastrulating tissue is surrounded by a rigid protective shell. So far, scientists did not know whether interactions between the living tissue and the protective shell provide additional forces that affect gastrulation. Studying the red flour beetle, researchers at the Biotechnology Center of the TU Dresden (BIOTEC), the Max Planck Institute of Molecular cell Biology and Genetics (MPI-CBG) and the Cluster of Excellence “Physics of Life” (PoL) recently discovered that the living tissue attaches firmly to the shell that surrounds the embryo. This attachment generates additional external forces that are required for proper gastrulation movements. The study is published in the journal Nature.

Do interactions in molecular and cellular networks follow the same organization principles as human social interplay?


A Researcher from TU Dresden Biotechnology Center found impressing analogies

To decode the underlying laws that govern the organization of life into molecules, cells and tissues are the great scientific challenges of our time. Dr. Carlo Vittorio Cannistraci from the Biotechnology Center (BIOTEC) at the Technical University Dresden, Germany, explored the question whether brain cells interact in the same manner as molecules within a cell and published his findings in the science magazine Nature.

He found that the self-organization within these two systems follows the same principles - regardless the size of the structures and independent from what body functions they support. He codified those complex interactions in a mathematic model that is able to predict protein molecule interactions within the body under changed conditions.

A novel synthetic antibody enables conditional “protein knockdown” in vertebrates


The research groups led by Dr. Jörg Mansfeld of the Biotechnology Center of the TU Dresden (BIOTEC) and Dr. Caren Norden of the Max Planck Institute for Molecular Cell Biology and Genetics (MPI-CBG) have developed a novel synthetic antibody that paves the way for an improved functional analysis of proteins. They combined auxin-inducible "protein knockdown" with a synthetic antibody to not only observe fluorescent proteins in living cells but also to rapidly remove them in a temporally controlled manner.

Dr. Jörg Mansfeld's research group has developed a novel AID-nanobody in order to not only observe GFP-linked proteins in living cells, but to also rapidly degrade them in a targeted manner for functional analysis. For this purpose, the auxin recognition sequence (AID) was linked to a GFP recognizing antibody that is structurally-related to camelid antibodies (nanobody). It could be shown that this so-called AID-nanobody allows the almost complete degradation of GFP-linked proteins in human cell culture after the addition of auxin. The possibility to follow the degradation of the protein "live" under the microscope makes functional analysis much easier.

Rapid diagnosis of diseases with novel blood test


Prof. Dr. Jochen Guck, research group leader at the Biotechnology Center of TU Dresden (BIOTEC), together with medical colleagues from the University Hospital Carl Gustav Carus Dresden and partnering institutes from Dresden (Germany), Cambridge (UK), Glasgow (UK), and Stockholm (Sweden) use a technique called "real-time deformability cytometry" to screen thousands of cells in a drop of blood for unusual appearance and deformability in a matter of minutes. This novel blood test promises to speed up the correct diagnosis of many disease conditions including leukaemia, malaria, bacterial or viral infections, which in turn can lead to a faster and more accurate start of therapy.

The bright side of an infectious protein: Stress sensors promote yeast cell survival


Prions are self-propagating protein aggregates that can be transmitted between cells. The aggregates are associated with human diseases. Indeed, pathological prions cause mad cow disease and in humans Creutzfeldt-Jakob disease. The aggregation of prion-like proteins is also associated with neurodegeneration as in ALS. The regions within prion-like proteins that are responsible for their aggregation were termed prion-like domains. Despite the important role of prion-like domains in human diseases, a physiological function has remained enigmatic. Researchers at the Max Planck Institute of Molecular Cell Biology and Genetics (MPI-CBG), the Biotechnology Center of the TU Dresden (BIOTEC, Grill group), and the Washington University in St. Louis, USA have now identified for the first time a benign, albeit biologically relevant function of prion domains as protein specific stress sensors that allow cells to adapt to and survive environmental stresses. Uncovering the physiological function is an essential first step towards closing a gap in understanding the biological role of prion domains and their transformation into a pathological disease-causing state. The discoveries were published in Science.
