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.

Cell division, cell differentiation, cell repair and cell death play fundamental roles in the human organism, its development, health and reproduction. Cellular transformation processes are governed by two regulatory mechanisms: chromatin modifications and cell signaling networks. The EpiSignal Research Training Group sheds light on the hitherto little-researched interplay between these two complex systems.

Cardiovascular diseases, including stroke and myocardial infarction, are the world's leading causes of mortality, accounting for over 18 million deaths a year. A team of KIT researchers has now identified a new cell type in blood vessels responsible for vascular growth. This discovery may allow for novel therapeutic strategies to treat ischemic cardiovascular diseases, i.e. diseases that are caused by reduced or absent blood flow.

Heidelberg scientists unveil genetic programmes controlling the development of cellular diversity in the cerebellum of humans and other mammals. The research results have now been published in the journal Nature.

After infections or blood loss, the body must compensate for the loss of blood cells as quickly as possible. This has long been considered the task of the hematopoietic stem cells in the bone marrow. But scientists at the German Cancer Research Center (DKFZ) have now discovered in mice that a certain population of progenitor cells takes over this task: This accelerates the regeneration of the blood cells.

In the brain of adult mammals neural stem cells ensure that new nerve cells, i.e. neurons, are constantly formed. This process, known as adult neurogenesis, helps mice maintain their sense of smell. A research team led by Dr Francesca Ciccolini at the Interdisciplinary Center for Neurosciences (IZN) of Heidelberg University recently discovered a second stem cell population in the mouse brain.

Under certain conditions, our immune system can efficiently fight off infectious diseases and cancer. T cells, especially the gamma delta T cell type, play an important role in this. The issue is that this cell type is extremely infrequent in the human body. Researchers at the University Hospital Tübingen, the University of Heidelberg and the European Molecular Biology Laboratory (EMBL) have now succeeded in finding the cause for the formation of…

Induced pluripotent stem cells (iPSC) are suitable for discovering the genes that underly complex and also rare genetic diseases. Scientists from the German Cancer Research Center (DKFZ) and the European Molecular Biology Laboratory (EMBL), together with international partners, have studied genotype-phenotype relationships in iPSCs using data from approximately one thousand donors.

HepaRegeniX develops an active substance for liver regeneration

When the liver stops regenerating on its own, it might be possible in future for doctors to intervene with a chemical agent. Tübingen-based HepaRegeniX GmbH is developing a promising candidate with the aim of improving the treatment of both acute and chronic liver failure.

Epigenetics – heritable traits without changing the DNA sequence

Epigenetics, i.e. the inheritance of traits that does not involve a change in the DNA sequence, was once a controversial subject that has since become a central focus of biological research. Epigenetic inheritance is now studied by numerous national and international research programmes. Many cellular regulatory and differentiation processes are controlled by epigenetic mechanisms that take place on different levels.

Evo-devo - the synthesis of developmental biology and evolution

Evo-devo research has led to completely new ideas concerning the evolution of animals. The huge variety of animals is the result of changes in the activity of a limited number of master genes that control early embryonic development. These master genes have been highly conserved throughout evolution, which is why their analysis allows conclusions to be drawn concerning the evolution of multicellular animals and their different body plans.
