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.

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.

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.

Chromosomal instability plays a role in the progression of cancer: it shapes the properties of tumor cells and drives the development of therapy resistance. Scientists from the German Cancer Research Center (DKFZ), the Heidelberg Stem Cell Institute HI-STEM* and the European Molecular Biology Laboratory (EMBL) used state-of-the-art single-cell analysis methods to analyze the cellular heterogeneity of a specific form of acute myeloid leukemia.

An important enzyme helps the body produce selenium proteins – this discovery could open up new strategies for treating cancer in children. 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*.

Scientists at the German Cancer Research Center (DKFZ), together with doctors from the Urological Clinic of the Mannheim University Hospital, have developed and successfully tested a chatbot based on artificial intelligence. "UroBot" was able to answer questions from the urology specialist examination with a high degree of accuracy, surpassing both other language models and the accuracy of experienced urologists.

Whether we are predisposed to particular diseases depends to a large extent on the countless variants in our genome. However in the case of genetic variants the influence on the presentation of certain pathological traits has been difficult to determine. Researchers have introduced an algorithm based on deep learning that can predict the effects of rare genetic variants.

With mice, researchers showed that experimentally induced lack of blood flow in the brain epigenetically reprograms astrocytes into brain stem cells, which in turn can give rise to nerve progenitor cells. This discovery shows that astrocytes could potentially be used in regenerative medicine to replace damaged nerve cells.

Knowledge of the target structures for the immune cells is a basic prerequisite for the development of personalized cancer immunotherapies. Scientists from the German Cancer Research Center and the NCT Heidelberg are publishing a sensitive method based on mass spectroscopy to identify such tumor-specific "neoepitopes". The analytical method is designed to detect these low abundance protein fragments and requires minimal amounts of…

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.

Encouraging results from a large international study led by Heidelberg have recently been published in the journal “Lancet”: The genetic material of cancer cells with unknown tissue of origin contains numerous targets for specific drugs that are already available and have been developed to treat other forms of cancer. These suppressed the disease in CUP patients for significantly longer than chemotherapy.

The "Friends of the German Cancer Research Center" association supports the DKFZ and aims to help strengthen its position in international competition. With the DKFZ Innovation Award presented at this year's DKFZ annual reception, the association honored Titus Brinker as a researcher whose highly innovative work builds a bridge from research to practical application with commercialization potential.

Better immune response against prostate cancer thanks to new bispecific antibodies

TWYCE, a Tübingen-based start-up spun off from the German Cancer Research Center in Heidelberg and the Faculty of Medicine at the University of Tübingen, is focused on developing a combinatorial therapy using two bispecific antibodies from bench to clinical practice. The founders aim to introduce an effective strategy for combating solid tumours, with initial proof of concept targeted at prostate cancer.

The summer reception hosted by BioRegio STERN Management GmbH has once again provided a fitting backdrop for the Science2Start award ceremony. Last Thursday, at Tübingen observatory, was the 15th time that scientists and start-up founders were celebrated for outstanding ideas that a panel of experts judged to have special economic potential.

Scientists from the German Cancer Research Center (DKFZ) and Heidelberg University Hospital (UKHD) have shown that the combination of therapeutic immune cells, known as CAR T cells, and a bispecific antibody could improve the treatment of leukaemia. In the culture dish and in mice, they tested CAR-T cells directed against the B-cell marker CD19 in combination with bispecific antibodies that bind to the B-cell-specific protein CD20.

Heidelberg Epignostix GmbH, a deeptech start-up committed to precision cancer diagnostics today announces €4.3M in seed funding. This investment will enable Heidelberg Epignostix to make a substantial leap forward in driving market development for its flagship indication for brain tumor classification.

Gender-specific differences - 18/06/2024

Gender medicine: Why is good healthcare not a matter of course for everyone?

Gender medicine is the study of gender-specific health differences. Many diseases manifest themselves differently in men and women and therapies do not always have the same effect depending on the sex of the patient being treated. There is currently not enough data on these differences. Research teams including the one led by Professor Dr. Dr. Sonja Loges from the University Medical Centre Mannheim and the DKFZ are seeking to change this.

Cancer genomes are the result of diverse mutation processes. Scientists have analyzed the molecular evolution of tumors after exposure to mutagenic chemicals. DNA lesions that persists unrepaired over several cell generations lead to sequence variations at the site of damage. This enabled the researchers to distinguish the contribution of the triggering lesion from that of the subsequent repair in shaping the mutation pattern.

Depending on whether the cell nucleus of an epithelial cell is located on the outer or inner side of the tissue, the genome is more or less acetylated - genes can therefore be translated easier or harder. Scientists from the German Cancer Research Center (DKFZ) have demonstrated this for the first time in the development of the Drosophila wing.

Scientists from the German Cancer Research Center (DKFZ) and the European Bioinformatics Institute EMBL-EBI, Hinxton, UK, are using the Danish health registers to predict individual risks for 20 different types of cancer with a high degree of accuracy. The prediction model can also be transferred to other healthcare systems.

Colorectal cancer differs from patient to patient. That is why scientists are looking for characteristic tumors markers that allow to make predictions about the likely response to certain therapies and the individual prognosis. The aim is to identify colorectal cancer subtypes so that these can then be treated in a customized manner.

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.

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.

In the medicine of the future, tiny robots will navigate independently through tissue and medical instruments will indicate their position inside the body during surgery. Both require doctors to be able to localize and control the devices precisely and in real time. Scientists from the German Cancer Research Center (DKFZ) have now described a signaling method based on an oscillating magnet that can significantly improve such medical applications.

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.
