Cancer therapy and cancer diagnostics

Thanks to improved diagnostics and therapy, today’s cancer patients can live considerably longer than patients several years ago. Nevertheless, some cancers, especially the strongly metastatic ones, are difficult to treat. Therapies targeting immune cells or cancer stem cells could potentially improve the current situation.

So-called silent mutations have no effect on the composition of a protein. They are therefore not considered to promote cancer. However, scientists from the German Consortium for Translational Cancer Research (DKTK), partner site Essen, now describe in a case of kidney cancer an overlooked silent mutation with a major impact on prognosis.

Plastic products can be found everywhere in daily life, soft plastic in particular often being used for packaging or children's toys. These often contain so-called plasticizers which ensure that the material remains flexible. Because plasticizers are not bonded permanently to the plastic, they can escape from the material, meaning they can be absorbed by humans.

Dr Simon Binder has been awarded a five-year, 1.5 million euro grant from the Carl Zeiss Foundation for his research into novel neuroimplants. Binder will establish the early career research group ‘Biohybrid Neuroimplants based on Soft Hydrogel Electrodes’ at the University of Freiburg. It is affiliated with the research institutions BrainLinks-BrainTools.

Prof. Dr. Peter Loskill and Dr. Silke Riegger from the 3R Center Tübingen for in-vitro models and animal testing alternatives have been awarded the Ursula M. Händel Animal Welfare Prize 2024. The prize, endowed with 80,000 euros, was awarded to them in Würzburg for the development of organ-on-chip (OoC) systems as an alternative to animal testing.

Researchers of Karlsruhe Institute of Technology (KIT) and Voxalytic GmbH developed a new method that allows, for the first time, to elucidate the chiral structure of molecules – the exact spatial arrangement of the atoms – by nuclear magnetic resonance (NMR) spectroscopy. This important step in the development of new drugs used to be a time-consuming process until now.

Individual operation risk assessment by the Cognitive Medical Assistant

Despite modern surgical techniques and anaesthetic procedures, serious complications can occur during surgical interventions. An interdisciplinary team at Heidelberg University Hospital has launched a project called the Cognitive Medical Assistant (German: Der Kognitive Medizinische Assistant, KoMed for short), designed to better assess the individual risk of these interventions. The project’s goal is to systematically and comprehensively analyse…

Mitochondria are considered to be the power plants of cells and are essential for human metabolism. Dysfunction in 40 percent of mitochondrial proteins are associated with human diseases, which is why mitochondria also play an important role in medical research. A previously unexplained process in the complex mitochondria was the formation of their barrel pores.

All cancer cells - even those within the same tumor - differ from each other and change over the course of a cancer disease. Scientists at Heidelberg University Hospital, the Medical Faculty in Heidelberg and the German Cancer Research Center discovered molecular changes in multiple myeloma that help individual cancer cells to survive therapy.

Scientists at the German Cancer Research Center (DKFZ), together with doctors from the Urological Clinic of the Mannheim University Hospital, have developed and successfully tested a chatbot based on artificial intelligence. "UroBot" was able to answer questions from the urology specialist examination with a high degree of accuracy, surpassing both other language models and the accuracy of experienced urologists.

The reproducible and precise production of complex organoid models to simulate human organ malfunctions is the focus of an interdisciplinary research project at Heidelberg University. A research team from the life and engineering sciences is looking to combine the engineering of molecular systems with machine learning and automated production methods.

VDI Guideline 5708 “Bioprinting, methods and definitions”: What sounds technical and sober at first glance is an important step forward in the future field of 3D bioprinting. The guideline was developed under Dr. Hanna Hartmann from the NMI in Reutlingen and Prof. Dr. Jürgen Groll from the University Hospital of Würzburg. It creates a binding, practical basis for reproducible and quality-assured bioprinting procedures.

Investing in a healthier future: The HORNBACH Group is supporting the new National Cancer Prevention Center in Heidelberg with a donation of five million euros. In the future, a new laboratory will conduct research into more effective early detection and screening methods.

Researchers from the German Cancer Research Center (DKFZ) have collaborated with the SILVACX project group at Heidelberg University to develop a therapeutic vaccination concept that can mobilize the immune system to target cancer cells. The team showed that virus peptides coupled to silica nanoparticles can elicit effective T-cell responses against HPV-related tumors.

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) is funding a new Emmy Noether junior research group at the DKFZ for six years with a total of around 2 million euros. The scientists and doctors, who are part of the Clinical Cooperation Unit for Pediatric Leukemia at the KiTZ, are using a new procedure to investigate how cancer cells manipulate the formation of proteins to become resistant to cancer drugs.

Although just cute little creatures at first glance, the microscopic geckos and octopuses fabricated by 3D laser printing in the molecular engineering labs at Heidelberg University could open up new opportunities in fields such as microrobotics or biomedicine. The printed microstructures are made from novel materials – known as smart polymers – whose size and mechanical properties can be tuned on demand and with high precision.

The constant remodeling of the organs of the female reproductive tract during the reproductive cycle leads to fibrosis and chronic inflammation over the years. Scientists from the German Cancer Research Center (DKFZ) have now uncovered these unexpected long-term consequences of female reproductive function in mice. The results have been published in the scientific journal CELL.

A cutting-edge chemical process is the first to make it possible to quickly and easily produce modified peptides with boronic acids. As part of this work, scientists managed to synthesize a large number of different biologically active peptide boronic acids and investigate their properties. They open up new possibilities in the young research field of synthetic immunology and could go on to be used primarily in immunotherapy.

An important enzyme helps the body produce selenium proteins – this discovery could open up new strategies for treating cancer in children. This has been published by scientists from the University of Würzburg, the University Sao Paolo, the German Cancer Research Center (DKFZ) and the Heidelberg Stem Cell Institute HI-STEM*.

A team of researchers from HITS and MPIP have developed a model that learns how to generate proteins whose structures are highly flexible, even with patterns that are uncommon in natural proteins. Their work, presented at the International Conference on Machine Learning (ICML), marks a step towards the goal of designing new proteins for applications in biotechnology, therapeutics and environmental research.

The targeted engineering of artificial proteins with unique properties – that is possible with the assistance of a novel method developed by a research team of Heidelberg University. It centers around a new AI model. This allows for forecasting how two proteins have to be fitted together at the molecular level from individual parts – subunits – in order to engineer a functional, adjustable new protein.

A team of scientists from the German Cancer Research Center (DKFZ) and the Netherlands Cancer Institute has discovered a previously unknown vulnerability in cancer cells: When cell division is blocked with chemotherapeutic agents such as Taxol, cancer cells produce small immunogenic peptides that could open up new avenues for immune-based cancer therapies.

When embryos grow, cells and tissue are constantly bumping into each other. This creates mechanical tensions that could endanger their development. A team from University of Hohenheim and the Japanese RIKEN Center have discovered that fly embryos have strategies to deal with this pressure. The different species have developed two different solutions. This ability to control mechanical tension could be a key to why so many body plans have evolved.

A specific variant of the surface protein VSG of African trypanosomes, the causative agents of sleeping sickness, is associated with resistance to the important drug Suramin.
