The risk of colorectal cancer can be predicted more accurately by determining seven blood-based micro-RNAs (miRNAs) than by using traditional methods - and can be done so many years before a diagnosis is made. In a current study, researchers from the German Cancer Research Center and the National Center for Tumor Diseases (NCT) Heidelberg show that miRNA profiles provide greater predictive accuracy than genetic or lifestyle-based risk…

Development of anti-tumour agents - 20/03/2023

Targeting the protective shield of cancers

Cancer cells have different mechanisms to help them escape destruction by the immune system. Solid tumours, for example, are often surrounded by a protective layer of lactate, which has a strong immunosuppressive effect. WMT AG from Heidelberg is developing small drug molecules that reduce lactate production and thus make cancer cells vulnerable to immune system attacks.

Pancreatic cancer is one of the deadliest types of cancers in humans. Chemotherapies attack not only the tumor cells but also healthy cells throughout the body. Innovative nanoparticles could be a new approach to treat cancer more precisely. The approach was developed by a research team from the Max Planck Institute (MPI) for Multidisciplinary Sciences, the University Medical Center Göttingen (UMG), and the Karlsruhe Institute of Technology.

Tumour monitoring using liquid biopsy

Liquid biopsy, the analysis of cancer biomarkers and circulating tumour cells in body fluids such as blood, is revolutionising the diagnosis and monitoring of cancer. It has also been possible to expand circulating tumour cells from the blood under laboratory conditions. It is expected that in the future, liquid biopsy will be able to precisely characterise tumour cells at every stage of a cancer.

Tumor vaccines can help the body fight cancer. These vaccines alert the patient's immune system to proteins that are harbouring cancer-typical alterations. Physicians and cancer researchers from Heidelberg and Mannheim have now treated adult patients with advanced midline gliomas, difficult-to-treat brain tumors, with a peptide vaccine for the first time.

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 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.

Current diagnostic methods do not always reliably distinguish between chronic inflammation of the pancreas and pancreatic cancer. About one third of all diagnoses are inconclusive. Scientists from the German Cancer Research (DKFZ) and from Heidelberg University Hospital (UKHD) therefore searched for molecular markers that could specify this diagnosis.

CAR-T cell therapy is a last hope for many patients with blood, bone marrow or lymph gland cancer when other treatments are unsuccessful. A limiting factor of this very effective and safe therapy is that the cells used in the process quickly reach a state of exhaustion. Researchers at the University of Freiburg have now been able to prevent this exhaustion and thus significantly improve the effect of the therapy in a preclinical animal model.

Activated T cells that carry a certain marker protein on their surface are controlled by natural killer cells. In this way, the body presumably curbs destructive immune reactions. Researchers now discovered that NK cells can impair the effect of cancer therapies with immune checkpoint inhibitors in this way. They could also be responsible for the rapid decline of therapeutic CAR-T cells.

Colorectal cancer screening programs are currently underutilized in Germany. This also applies to testing for blood in the stool. The immunological stool tests can detect tiny amounts of blood in the stool. Scientists at the German Cancer Research Center (DKFZ) have investigated whether smartphone-based testing could be a meaningful alternative or supplement to traditional laboratory tests.

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.
