The ability of cancer cells to change their identity makes tumors such as glioblastoma particularly aggressive and resistant to treatment. Moritz Mall, of the German Cancer Research Center (DKFZ) and the Hector Institute for Translational Brain Research (HITBR), is investigating how this plasticity can be specifically restricted. His approach focuses on genetic “guardians” that suppress alternative cell programs.

A new technique based on labelled sugar molecules is providing previously unknown insights into the inner ear. A study by the University of Konstanz and Charité-Universitätsmedizin Berlin shows that the cupula in the inner ear of zebrafish completely regenerates within approximately two months. These findings open up a new avenue for research into sudden hearing loss and acute disorders of the sense of balance.

For the first time, researchers have succeeded in mapping the organization of immune cells in human lymph nodes. The study was led by scientists from Heinrich Heine University Düsseldorf, Düsseldorf University Hospital, the DKFZ, the European Molecular Biology Laboratory (EMBL), and the Max Delbrück Center (MDC) in Berlin. They were able to demonstrate why the architecture of healthy lymph nodes is altered in malignant lymphomas.

In ovarian cancer, immunotherapies using checkpoint inhibitors have so far been effective in only a small number of patients. Researchers at the HI-TRON Mainz* have now discovered that lipid metabolism processes in the tumor microenvironment play a decisive role in how well such therapies work. The findings open up new avenues for using immunotherapies in a more targeted manner, increasing their effectiveness, and overcoming resistance.

Traumatic brain injuries often lead to complications with long-lasting consequences on memory, concentration and movement control. Detrimental secondary inflammatory reactions at the injured tissue sites are often responsible for this. Researchers from Ulm have now shown that a transcription factor plays a key role in reactions to TBI. When this gene regulator is activated, an elevated neuroimmune response promotes inflammation.

A severe side effect of radiation therapy can be debilitating fibrotic skin damage. Scientists at the German Cancer Research Center (DKFZ) have now identified a key factor in the development of this radiation damage. Modulating this factor could potentially prevent this severe adverse effect.

Even before a tumour in the pancreas becomes discernible, an activated cancer gene actively remodels its future environment and creates an inflammatory and immune-defensive microenvironment in which the carcinoma can grow. The scientists' study opens up new possibilities for developing personalised intervention strategies - before a difficult-to-treat tumour even develops.

Can the weakened immune systems of older individuals be rejuvenated? Researchers from the DKFZ, HI-STEM*, and the Broad Institute have demonstrated that this is possible with an innovative approach. In a study, the team showed that mRNA technology can be used to transform the liver in mice into a temporary source of important immune regulatory factors that are naturally lost during aging.

Heidelberg University has been successful in the current approval round of the German Research Foundation (DFG) with three grant applications for major research consortia. In the life sciences and medicine, a Collaborative Research Centre working on the Wnt signaling pathway will enter its third funding period. Two transregional consortia with major participation by researchers from Ruperto Carola have also been extended.

In the current selection round, the German Research Foundation (DFG) has granted funding for two new Collaborative Research Centres at the University of Konstanz. Over the next four years, the research teams will be working intensively on trigger signals in biological cells as well as on "silence" and "noise" in human speech.

Researchers from the German Cancer Research Center and the University of Freiburg show how certain painkillers influence the iron metabolism of liver cancer cells and can thus contribute to iron deficiency and anemia in cancer patients.

A team from the DZHK sites in Heidelberg/Mannheim and Berlin has discovered that a single enzyme in the heart plays a key role in determining whether the organ develops in a healthy manner. If this molecular protective factor is missing, serious congenital heart defects can develop.

In the PRECISION-ImmunoRad project, a multidisciplinary team of scientists from Heidelberg, USA, and Cyprus will unite their expertise to develop novel curative therapeutic strategies for currently hard-to-treat cancers. These strategies will integrate high-precision ion beam therapy with genetically engineered immune cells therapies (CAR-T cells), personalized cancer vaccines, and the targeted reprogramming of the tumor immune microenvironment.

Tumors are not a comfortable place to live: oxygen deficiency, nutrient scarcity, and the accumulation of sometimes harmful metabolic products constantly stress cancer cells. 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.

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.

Alumnus Bastian Linder discusses the origin of this start-up and how a tRNA mechanism is helping scientists understand the importance and use of various RNA modifications as they pertain to disease.

Chordomas are rare bone tumors for which there are no effective drugs. A research team from the DKFZ and the NCT Heidelberg has now developed a promising approach: Tailor-made mini-proteins specifically block the driver of tumor development. In the result, slowing the growth of chordoma cells in the laboratory and in a mouse model, while also revealing further molecular vulnerabilities of the tumor that could be addressed with approved drugs.

Researchers at the University of Freiburg, together with partners, have uncovered the mechanism of ultrafast transport by calcium pumps in nerve cells. These pumps, complexes of PMCA2 and neuroplastin proteins, operate at more than 5,000 cycles per second and terminate calcium signals within milliseconds – 100 times faster than previously known. They play a crucial role in rapid information processing in the brain.

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.

FOXP1 syndrome is a congenital disorder in which the brain development of affected children is severely impaired due to a genetic variant. A research team from the Medical Faculty Heidelberg at Heidelberg University has now demonstrated in mice, that the inhibition of a specific enzyme in the brain can improve abnormal behavior and immune cell dysfunction in the brain. The results have been published in the journal Advanced Science.

EmbryoNet AI automatically identifies developmental disorders

In complex organisms, embryonic development is tightly regulated by intricate signalling pathways. When these pathways are disrupted, they can lead to characteristic developmental defects that are not easy to detect with the naked eye. Developmental biologist Prof. Dr. Patrick Müller from the University of Konstanz has developed EmbryoNet, an AI-powered software tool that uses image analysis to reliably identify such developmental disorders.

The ability of protein kinases to transfer a phosphate group to target proteins plays an important role in many cellular processes. Scientists at the Max Planck Institute for Medical Research have now developed a novel molecular tool that can monitor these kinase activities both spatially and temporally. This makes it possible to investigate the link between kinase activities and cellular phenotypes in heterogenous cell populations and in vivo.

An international team of researchers led by Konstanz biologists has identified a molecular mechanism that regulates the activity of N-myristoyltransferases. This enzyme plays a role in biological signalling pathways, where dysregulation can lead to serious illness.
