Tumor vaccines can help the body fight cancer. Mutations in the tumor genome often lead to protein changes that are typical of cancer. A vaccine can alert the patients' immune system to these mutated proteins. For the first time, physicians and cancer researchers from Heidelberg and Mannheim have now carried out a clinical trial to test a mutation-specific vaccine against malignant brain tumors.

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…

A new method allows stem cells and cancer stem cells to be studied at the single cell level and the resulting cell clones to be traced directly.

Epigenetic switches in bacteria as biosensors

The analysis of pathogen biomarkers and biomarkers for the diagnosis of diseases can be crucial for health. However, the detection of pathogens and diseases depends on a sensitive and reliable method that delivers rapid results. Biosensors have such properties. Researchers at the Institute of Biochemistry and Technical Biochemistry (IBTB) at Stuttgart University have constructed an epigenetic circuit composed of plasmids that might make it…

Do BMMFs, the novel infectious agents found in dairy products and bovine sera, play a role in the development of colorectal cancer? Scientists led by Harald zur Hausen detected the pathogens in colorectal cancer patients in close proximity to tumors. The researchers show that the BMMFs trigger local chronic inflammation, which can cause mutations via activated oxygen molecules and thus promote cancer development in the long term.

Women have an increased risk of breast cancer if they have a family history of this disease. However, the risk may also be higher if first-degree family members have another type of cancer, according to a study by a team of scientists and physicians from the National Center for Tumor Diseases (NCT) Heidelberg, the German Cancer Research Center (DKFZ) and Heidelberg University Hospital (UKHD), as well as international colleagues.

Faster to single cells using miniature grinder

Tissue cells are needed for medical diagnostics, cell therapies and tissue engineering, among other things. A novel tissue grinder gently and automatically dissociates cells from tissue. In November 2020, the newly founded biotech company Fast Forward Discoveries GmbH (FFX) delivered its first tissue grinders to customers.

Induced pluripotent stem cells (iPSC) are suitable for discovering the genes that underly complex and also rare genetic diseases. Scientists from the German Cancer Research Center (DKFZ) and the European Molecular Biology Laboratory (EMBL), together with international partners, have studied genotype-phenotype relationships in iPSCs using data from approximately one thousand donors.

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.

Neuroblastoma can spread relentlessly or shrink spontaneously. Scientists from the Hopp Children’s Cancer Center Heidelberg (KiTZ), the German Cancer Research Center (DKFZ), the University of Heidelberg and the National Center for Tumor Diseases (NCT) Heidelberg have shown that some malignant neuroblastomas employ a trick to avoid cell death: they use a special mechanism to lengthen the telomeres at the end of their chromosomes.

Certain anchor proteins inhibit a key metabolic driver that plays an important role in cancer and developmental brain disorders. Scientists from the German Cancer Research Center (DKFZ) and the University of Innsbruck, together with a Europe-wide research network, discovered this molecular mechanism, which could open up new opportunities for personalized therapies for cancer and neuronal diseases. They published their results in the journal Cell.

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. Scientists at the German Cancer Research Center have now been able to find a possible explanation for the formation of resistance based on the crystal structure of this protein variant.

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.

The Freiburg engineer and biologist Prof. Dr. Barbara Di Ventura receives a Consolidator Grant from the European Research Council (ERC), one of the most prestigious prizes for European researchers, for her project "InCanTeSiMo - Intelligent cancer therapy with synthetic biology methods". Di Ventura will use the 2 Million Euros to develop a novel cancer treatment based on molecular methods from synthetic biology.

AI-based evaluation of medical imaging data usually requires a specially developed algorithm for each task. Scientists from the German Cancer Research Center (DKFZ) have now presented a new method for configuring self-learning algorithms for a large number of different imaging datasets – without the need for specialist knowledge or very significant computing power.

Whole genome sequencing for diagnosing rare diseases

Grouped together, rare diseases are by no means a rare phenomenon; however, they are rarely correctly diagnosed and rarely properly treated. In most cases, there is no effective medication available. Rare disease centres staffed by experts have been set up in many German cities to speed up the often long and painful search for the right diagnosis and treatment. Whole genome sequencing is a component of general healthcare, used to identify…

A Phase I clinical trial using a self-developed vaccine against SARS-CoV-2 was initiated today at the University Hospital of Tübingen. In contrast to the currently evaluated vaccine candidates against COVID-19, the vaccine CoVAC1, developed by the Department of Immunology (Director Prof. Hans-Georg Rammensee) at the University of Tübingen, aims specifically at the induction of a T-cell-mediated immune response against SARS-COV-2.

“Molecular glue degraders” are a new class of cancer drugs, which “glue” cancer growth-promoting proteins directly to the molecular machinery of a cell’s disposal system, leading to the subsequent degradation of the cancer-driving proteins and anti-tumor activity. Scientists from Heidelberg and USA have now deciphered another mechanism whereby a small molecule can degrade a cancer protein.
