The results of a Tuebingen-led study raise hope that a newly developed drug could herald a new era in oncological liver surgery and transplantation. The drug could even have the potential to significantly improve the treatment of acute and chronic liver diseases. The drug candidate "HRX-215" is a so-called MKK4 inhibitor, i.e. the drug inhibits the MKK4 protein found in liver cells and thus leads to an increase in the regeneration of…

Immunotherapy using checkpoint inhibitors is effective in around a quarter of patients with liver cancer. However, to date, physicians have been unable to predict which patients would benefit from this type of treatment and which would not. Researchers from the German Cancer Research Center have now discovered that liver cancer caused by chronic inflammatory fatty liver disease does not respond to this treatment. On the contrary: in an…

HepaRegeniX develops an active substance for liver regeneration

When the liver stops regenerating on its own, it might be possible in future for doctors to intervene with a chemical agent. Tübingen-based HepaRegeniX GmbH is developing a promising candidate with the aim of improving the treatment of both acute and chronic liver failure.

HepaRegeniX GmbH, a clinical stage company developing a novel regenerative therapy for the treatment of acute and chronic liver diseases, announced the closing of a Series C round led by Vesalius Biocapital IV with participation of existing investors Novo Holdings, Boehringer Ingelheim Venture Fund (BIVF), and High-Tech Gründerfonds. The new funds of €15 million will be used to advance the clinical development of the clinical candidate HRX-215.

A high-fat, high-sugar diet damages the liver in the long term. Scientists at the German Cancer Research Center (DKFZ) have now identified a characteristic change in the molecular signaling pathways of liver cells in mice that were exposed to such a diet for weeks. It fuels the division activity of hepatocytes and correlates with the risk of patients suffering liver failure after liver surgery.

Fatty liver disease often leads to chronic liver inflammation and can even result in liver cancer. Scientists from the German Cancer Research Center (DKFZ) and the University of Tuebingen have now shown in mice that intermittent fasting can halt this development.

CureVac N.V. (Nasdaq: CVAC), a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (“mRNA”), today announced the publication entitled “Therapeutic HNF4A mRNA attenuates liver fibrosis in a preclinical model” in the peer-reviewed Journal of Hepatology.

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions have hardly been studied to date. Researchers from the German Cancer Research Center, the Mannheim Medical Faculty and Columbia University have now published that hepatic stellate cells control liver metabolism as well as liver regeneration and size. The results of the study could contribute to new therapeutic approaches for liver diseases.

Inflammatory fatty liver disease (NASH, non alcoholic steatohepatitis ) and the resulting liver cancer are driven by autoaggressive T cells. Scientists from the German Cancer Research Center (DKFZ) now show what ist behind this destructive behavior. In both mice and humans with NASH, they found increased numbers of activated B cells in the gastrointestinal tract.

Advances in the study and treatment of liver diseases

Liver diseases are often underestimated despite being quite common and potentially having serious and even life-threatening consequences, especially in chronic cases. The most common causes of liver diseases are hepatitis viruses, excessive alcohol consumption, and obesity; congenital or autoimmune liver diseases are quite rare. Thanks to advances in medical research, diseases such as hepatitis B and C can be treated effectively.

People with metabolic dysfunction-associated steatotic liver disease (MASLD) and more so with metabolic dysfunction-associated steatohepatitis and MASLD-associated hepatic fibrosis can progress to cirrhosis and hepatocellular carcinoma and are at increased risk of developing type 2 diabetes, cardiovascular and chronic kidney disease, and cancers. Future research might be beneficial for implementing precision medicine in MASLD.

A guardian molecule ensures that liver cells do not lose their identity. The discovery is of great importance for cancer medicine because a change of identity of cells has come into focus as a fundamental principle of carcinogenesis for several years. The research team was able to show that the newly discovered guardian is so powerful that it can slow down highly potent cancer drivers and cause malignant liver tumors to regress in mice.

Scientists from the EMBL and the German Cancer Research Center have presented a new method for generating metabolic profiles of individual cells. The method, which combines fluorescence microscopy and a specific form of mass spectroscopy, can analyze over a hundred metabolites and lipids from more than a thousand individual cells per hour. Researchers expect the method to better answer a variety of biomedical questions in the future.

Systems biology understanding complex biological systems

Systems biology studies complex interactions within biological systems on the genome proteome and organelle level. Many techniques from the fields of systems theory and associated fields can be used to gain an understanding of the behaviour and biological mechanisms of cellular systems.

Glycolysis is an important sugar degradation pathway that cancer cells in particular depend on. Scientists at the German Cancer Research Center (DKFZ) have now shown that liver cancer cells in mice and humans depend on a key enzyme of glycolysis, Aldolase A. When it is switched off, glycolysis reverses from an energy-producing to an energy-consuming process.

Cyber Valley researchers have created medical educational tools that could potentially train the surgeons of the future, much like flight simulators train pilots. The team developed a range of artificial organ phantoms to serve as training platforms for surgeons. Thanks to the structured data of experienced medical professionals, a quantitative and objective assessment of a trainee’s skills can be assessed in real time.

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.

A phase I clinical trial is now starting at Tuebingen University Hospital in the Clinical Collaboration Unit (CCU) Translational Immunology, in collaboration with the Department of Internal Medicine I, which is investigating the therapeutic cancer peptide vaccine Fusion-VAC-XS15 in combination with immune checkpoint blockade by atezolizumab (Tecentriq®).

Cancer genomes are the result of diverse mutation processes. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals. DNA lesions that persists unrepaired over several cell generations lead to sequence variations at the site of damage. This enabled the researchers to distinguish the contribution of the triggering lesion from that of the subsequent repair in shaping the mutation pattern.

They are underestimated genetic control elements: it is known that changes in the genome can trigger diabetes. But now researchers at the University Hospital Ulm and the INSERM Cochin Institute in Paris have shown that a previously under-researched region of the genome also plays a crucial role in the development of this disease.

Newly discovered RNA as growth driver in liver cancer

Non-coding RNA (ncRNAs) molecules that do not encode proteins have many different functions, and some are associated with certain diseases. Prof. Dr. Sven Diederichs from the German Consortium for Translational Cancer Research and the German Cancer Research Center in Heidelberg has been conducting research into these molecules at the Freiburg University Medical Centre and discovered a ncRNA that regulates cell proliferation in cancer cells.

Pancreatic cancer is one of the deadliest types of cancers in humans. Chemotherapies attack not only the tumor cells but also healthy cells throughout the body. Innovative nanoparticles could be a new approach to treat cancer more precisely. The approach was developed by a research team from the Max Planck Institute (MPI) for Multidisciplinary Sciences, the University Medical Center Göttingen (UMG), and the Karlsruhe Institute of Technology.
