This has been published by scientists from the University of Würzburg, the University Sao Paolo, the German Cancer Research Center (DKFZ) and the Heidelberg Stem Cell Institute HI-STEM*.

Certain childhood tumors have an extreme need for amino acids. Scientists at the Hopp Children's Cancer Center Heidelberg (KiTZ), the German Cancer Research Center (DKFZ), the University of Heidelberg, and HI-STEM* gGmbH have now discovered the molecular mechanisms underlying this and how the cancer cells could be turned off.

Christiane Opitz, scientist at the German Cancer Research Center, is being awarded this year's Ita Askonas Prize of the European Federation of Immunological Societies. Opitz has discovered how tumor cells use certain metabolites to protect themselves against the immune system. Her research findings may provide important clues for the development of new therapeutic concepts.

A precursor of cholesterol can protect cancer cells from a form of cell death known as ferroptosis. Scientists of the University of Würzburg, the German Cancer Research Center (DKFZ), and the Stem Cell Institute HI-STEM* published this finding in the journal Nature. The results opens up exciting prospects for further improving the treatment of cancer and other diseases associated with oxidative stress and ferroptosis.

Making a personalised T cell therapy for cancer patients currently takes at least six months; scientists at the German Cancer Research Center (DKFZ) and the University Medical Center Mannheim have shown that the laborious first step of identifying tumor-reactive T cell receptors for patients can be replaced with a machine learning classifier that halves this time.

Metastatic breast cancer requires complex and lengthy treatment, the side effects of which affect the quality of life of patients. These often include sexual problems. In a large international randomized exercise intervention trial, researchers have now shown that women who received a nine-month supervised exercise program reported significantly fewer symptoms than women who did not participate in the training program.

The recently established ITCC-P4 gGmbH provides academic institutions and pharmaceutical companies with a comprehensive repertoire of modern laboratory models of pediatric tumors. The aim is to systematically test new treatment options for children and adolescents with cancer and to contribute data to regulatory approval processes in order to make the development of new cancer therapies for children and adolescents more attractive.

The International Agency for Research on Cancer (IARC), an agency of the World Health Organization (WHO), will soon publish the first edition of its classification of childhood cancers. The new WHO classification forms the basis of modern, precise cancer diagnostics for physicians and pediatric oncologists worldwide and is based on the latest international research findings.

The development of immunotherapies against blood cancer could be more successful if T cells are activated moderately rather than excessively. Scientists from the German Cancer Research Center have now been able to show this in mice: If the researchers blocked a cytokine that slows down the immune system, the T cells became exhausted and failed in the fight against leukemia.

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.

Scientists at the German Cancer Research Center (DKFZ) have developed a completely new vaccination concept. The vaccine is inexpensive and protects mice against almost all cancer-causing HPV types. In addition to preventing new infections, the vaccine also triggers cellular immune responses against HPV-infected cells and may therefore also have a therapeutic effect against existing infections.

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.

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.

Germany's most important award for young scientists honors the development of immunotherapies against malignant brain tumors.

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.

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.

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.

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.

An international study with about 3000 patients confirms the validity of a new classification system for meningiomas. It combines tissue characteristics (histology) with molecular analyses and thus improves therapy planning.

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

The function of mast cells, which are part of the immune system, is still a mystery. Scientists at the German Cancer Research Center (DKFZ) have now shown in mice: mast cells function as a sensor that signals the animals to avoid antigens, including harmful allergens, and thereby protect themselves from health-threatening inflammatory reactions. The findings were published in the journal Nature.

BioMed X and the Universitätsmedizin Mannheim announced today the publication of two manuscripts in the field of cancer immunology in the journal Science Advances. The work is based on a collaboration bet- ween both institutions and researchers at the German Cancer Research Center (DKFZ), the Heidelberg Uni- versity, and the Helmholtz Institute for Translational Oncology (HI-TRON).

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.

Cancer cells often grow in environments that are low in nutrients, and they cope with this challenge by switching their metabolism to using proteins as alternative "food". Building on genetic screens, an international team of scientists could identify the protein LYSET as part of a pathway that allows cancer cells to make this switch. Their findings are now published in the journal Science.
