Researchers at the German Cancer Research Center (DKFZ) have succeeded in identifying a resistance mechanism that often occurs in a specific targeted therapy against chronic lymphocytic leukemia (CLL). The drug ibrutinib is effective in many cases, but therapy resistance often develops during the course of treatment. In cell culture experiments and in mice, the resistance mechanism was successfully overcome using a second drug.

Stomach ulcers, gastritis and even stomach cancer are often the result of an infection with Helicobacter pylori. If the bacterium remains unrecognised for a long time, this can have serious consequences. Researchers have now developed a miniaturisable sensor system for the mobile analysis of breath that is effective, fast and inexpensive. The research team uses a biological survival trick of the stomach germ to detect the bacterium.

The weight of expectant mothers could play a role in the development of acute lymphoblastic leukemia (ALL) in daughters – but not in sons. This has been shown by researchers at the German Cancer Research Center (DKFZ).

Researchers have developed a promising cellular immunotherapy for the treatment of glioblastomas: They equipped T cells with a receptor that recognizes a protein of the brain tumors that is responsible for the dangerous stem cell properties. The therapeutic T cells directed against this target structure were able to specifically destroy human brain tumors in laboratory experiments and in mice.

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.

Donating blood saves lives – but what long-term effects does this practice have on our bodies? Researchers from the German Cancer Research Center (DKFZ), the HI-STEM stem cell institute* and the German Red Cross Blood Donor Service, among others, have now discovered that frequent blood donations cause genetic adaptations in blood stem cells that promote the regeneration of blood cells.

Researchers have developed a new method that enables a more precise analysis of individual tumor cells circulating in the blood. This allows not only the previously possible genomic investigation of such tumor cells, but also the focused analysis of single-cell signaling pathways at the functional protein level. The combined analysis of the mutated genome and signaling proteins opens up new avenues for more targeted treatment methods.

This year, the Brain Prize worth more than one million euros, honors pioneering work on nervous system-cancer interactions: Neurologist Frank Winkler, who researches at the Heidelberg University and at the German Cancer Research Center and treats patients with brain tumors at the Heidelberg University Hospital, discovered that nerve cells in the brain communicate with brain tumor cells. This causes the disease to progress.

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.

The Bayer Foundation's Early Excellence in Science Award 2024 in the category of Data Science goes to Ivana Winkler of the German Cancer Research Center (DKFZ). Winkler's work uncovered the unexpected effect of female reproductive capacity: the constantly recurring remodeling of the organs of the female reproductive tract during the sexual cycle leads to fibrosis and chronic inflammation over the years.

Pancreatic cancer is fueled by connections to the nervous system. This is reported by scientists from the German Cancer Research Center (DKFZ) and the Heidelberg Institute for Stem Cell Technology and Experimental Medicine (HI-STEM)*. The team discovered that the tumor reprograms the neurons for its own benefit.

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 German Cancer Research Center (DKFZ) and ShanghaiTech University have developed an innovative method for growing brain tumors of individual patients in the laboratory that mimic the original structure and the molecular property of the parental tumor as closely as possible. Drug tests in this model were found to correlate very well with actual patient responses, making it a valuable method for investigating therapies.

The spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a basic requirement for producing proteins. Researchers at the Heidelberg University Biochemistry Center (BZH) have succeeded for the first time in depicting a faultily “blocked” spliceosome at high resolution and reconstructing how it is recognized and eliminated in the cell.

A research team from the Heidelberg Medical Faculty, the German Cancer Research Center, the Berlin Institute of Health at Charité (BIH) and the Max Delbrück Center has discovered new details about the spread of the incurable bone marrow cancer multiple myeloma in the body: When the cancer cells break out of the bone and multiply outside the bone marrow, a wide variety of tumor cells arise, accompanied by a significantly altered immune response.

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.

Young patients suffering from two aggressive sarcoma types can now participate in the innovative PAMSARC therapy study at the NCT Heidelberg. The study uses molecular biological methods and tests the extent to which a new drug can improve the poor prognosis for these tumours.

If the development of blood vessels in the placenta is impaired, fetal growth retardation may result. Scientists from the German Cancer Research Center (DKFZ) and the Mannheim Medical Faculty of Heidelberg University discovered that the correct development of functioning blood vessels in the mouse placenta is controlled epigenetically: One of the enzymes that modify gene activity using methyl groups is responsible.

A research team from Freiburg and Frankfurt has discovered how cells recognise and internally break down waste. The results are relevant for the development of therapies for diseases such as Alzheimer’s.

Tumor cells circulating in the blood are the "germ cells" of breast cancer metastases. They are rare and could not be propagated in the culture dish until now, which made research into therapy resistance difficult. A team from the DKFZ, the Heidelberg Stem Cell Institute HI-STEM and the NCT Heidelberg has now succeeded for the first time in cultivating stable tumor organoids directly from blood samples of breast cancer patients.

Up to now, schizophrenia has mainly been treated symptomatically, as little is known about the exact underlying processes. Researchers at the NMI Natural and Medical Sciences Institute in Reutlingen have succeeded in gaining a better understanding of the driving mechanisms of the disease. This offers opportunities for the development of new drugs. They have published their findings in the journal BMC Psychiatry.

The Gottfried Wilhelm Leibniz-Prize 2025 goes to Prof. Dr Robert Zeiser for his outstanding research in haematology and immunology. Zeiser’s research at the University of Freiburg and the Medical Center – University of Freiburg have led, among other things, to new types of cancer therapy that has increased survival rates and the patients’ quality of life.

Researchers at the Medical Faculty of Heidelberg University and the Heidelberg University Hospital have used modified rabies viruses to label glioblastoma tumour cells and their direct cell contacts in the mouse brain. The new method showed that the tumour cells are connected to different types of nerve cells throughout the entire brain at a very early stage of the disease.
