A key molecular mechanism drives the growth of liver cell cancer while simultaneously suppressing the body's immune response to the tumor. This has now been published in the journal Nature by a team led by researchers from the DKFZ, the UKT, and the Sanford Burnham Prebys Medical Discovery Institute. However, the results also show that this very mechanism could help identify patients who respond particularly well to immunotherapy in the…

Developing replacement methods for animal testing is the main goal of the 3R network. One of three new 3R centres in Baden-Württemberg was launched at Ulm University at the beginning of the year and has now officially started work with a kick-off event. The abbreviation 3R stands for "Replace, Reduce, Refine", i.e. replace and reduce animal testing and improve the conditions for unavoidable animal experiments.

Researchers at the German Cancer Research Center (DKFZ) have achieved outstanding success at this year's world-leading forum for medical image processing and computer-assisted intervention.

A research team from the DKFZ and the IMP in Vienna has now discovered that the acidic pH value in tumor tissue is a decisive factor in how pancreatic cancer cells adapt their energy metabolism in order to survive under these adverse conditions.

Human immunodeficiency viruses (HIV) are insidious. They can evade the immune defence and antiviral drugs by becoming "latent". In this state, they are largely invisible and unassailable. As long as these dormant viruses persist, there is no cure for HIV/AIDS. However, researchers at Ulm University Hospital have discovered a new way to reactivate latent HI viruses.

An imaging technique developed by Freiburg researchers provides insights into cardiac arrhythmias that can cause sudden cardiac death in animal models. The changes discovered could explain why even seemingly healthy people are sometimes affected.

Researchers from the Cluster of Excellence CIBSS have demonstrated that an actin scaffold stabilizes the cell nucleus upon mechanical stress. This protective mechanism helps cancer cells to avoid dying during their migration in the body. In the long term, targeted interventions in this mechanism could help to prevent metastases.

Why is blood cancer particularly aggressive in some patients? Researchers at Ulm University Hospital have characterised a mutation in the so-called NOTCH1 gene that significantly influences the prognosis of chronic lymphocytic leukaemia (CLL). Remarkably, this mutation is located in the non-coding region of the gene – an area of DNA long considered less relevant for disease mechanisms.

About five percent of lung adenocarcinomas, one of the most common forms of lung cancer, are driven by a faulty fusion of two genes, EML4 and ALK. This fusion results in different variants, and until now, clinicians have treated all patients with these fusions the same way. However, new research led by scientists from the German Cancer Research Center (DKFZ) and Stanford University shows that not all fusion variants behave alike.

The 2020 Nobel Prize in Chemistry was awarded for the development of CRISPR/Cas9, a method also known as “gene scissors”, which enables researchers to better understand how human cells function and stay healthy.

Researchers at Heidelberg Uni Hospital have decoded a previously unknown mechanism by which HIV-1 selects its integration targets in the human genome. A research team identified RNA:DNA hybrids as molecular signposts for the virus. These findings reveal a vulnerability in the life cycle of HIV and provide therapeutic approaches for specifically controlling HIV reservoirs in the body. This has been one of the obstacles to curative HIV therapies.

The cellular environment of a tumor can either support or sabotage recovery. The most comprehensive study to date on the tumor microenvironment in low-grade gliomas, conducted by KiTZ, Jena University Hospital, the DKFZ, and Heidelberg University Hospital, shows what a supportive or obstructive “neighborhood” looks like in childhood brain tumors. The study also provides clues as to how tumor communication might be blocked.

In the human body, stem cells process genetic information in an exceptionally reliable and very fast manner. To do this, they access certain sections of the DNA in the cell nucleus.

Until now, the early phase of drug discovery for the development of new therapeutics has been cost- and time-intensive. Researchers at KIT have developed a platform on which extremely miniaturized nanodroplets with a volume of 200 nanoliters per droplet and containing 300 cells per test can be arranged. This platform enables the researchers to synthesize and test thousands of therapeutic agents on the same chip, saving time and resources.

Every brain tumor is made up of cells in successive stages of activation. Researchers have now analyzed the individual structure of these activation pyramids in malignant brain tumors. In doing so, they discovered a signaling protein that slows down the transition from a dormant to an activated state by epigenetically reprogramming the cells. The hope is that this will permanently freeze cancer cells in a dormant state and thus halt tumor growth.

If the brain no longer responds properly to insulin (insulin resistance), this can lead to overweight, diabetes, and Alzheimer's disease. Researchers at the DZD in Potsdam and Tübingen have discovered small chemical modifications to genetic material (epigenetic changes*) in the blood that indicate how well the brain responds to insulin. These markers could help to detect insulin resistance in the brain – by means of a simple blood test.

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.

The results have been published in the journal Advanced Science.

Breath test replaces invasive diagnostics - 30/07/2025

To address this, researchers have developed an affordable breath test that uses a mini-sensor to detect the presence of the bacterium. They are currently working on a smartphone-compatible version for self-testing.

Designing protein binders from scratch has long been a daunting challenge within the field of computational biology. Researchers have now developed an innovative, training-free pipeline that uses the fundamental principle of shape complementarity to design site-specific protein binders, which are then optimised to fit precisely onto chosen target sites. The researchers tested this on proteins linked to cancer.

Stem cell-like leukemia cells are responsible for relapses in children and adolescents with a certain type of blood cancer, T-ALL. Researchers at the Hopp Children's Cancer Center Heidelberg (KiTZ), the Molecular Medicine Partnership Unit and the German Cancer Research Center were able to show this in a study. The results could help to overcome resistance in this form of blood cancer and prevent relapses.

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body - not only during normal tissue formation and wound healing, but also when tumor cells metastasize. This makes the enzyme an interesting candidate for potential future therapeutic approaches.

Diabetics have a higher risk of colorectal cancer and often a poorer prognosis after developing the disease. The biological mechanisms behind this association were largely unknown. A research team at the German Cancer Research Center (DKFZ) has now discovered that tumors with a low number of immune cells appear to be particularly susceptible to the harmful effects of diabetes.

Many people with cancer experience dramatic loss of muscle and fat tissue. In many cases, even the heart muscle is affected. This wasting syndrome, affects around half of all cancer patients.

Bacteriophages - viruses that specifically attack and destroy bacteria - are emerging as promising alternatives to antibiotics in the fight against drug-resistant infections. To speed this effort, researchers have created PhARIS, a computational tool that mines genomic data to pinpoint phages that are effective against S. aureus. By rapidly matching phage and pathogen, PhARIS can accelerate the development of targeted phage therapies.

Sarcomas in soft tissue usually occur in young people and are difficult to treat. Due to a lack of laboratory models, the causes of their development are poorly understood. A team of researchers has now succeeded in creating mouse models with a functioning immune system that replicate sarcoma types that remain unstudied. The method opens up new avenues for the targeted development of immunotherapies for children and adolescents with sarcomas.
