This stress inhibits tissue regeneration in humans and mammals as they age. In Zebrafish a signalling protein ensures that the cells of the damaged organ continue to divide and thus multiply.

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.

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.

In the current approval round of the German Research Foundation (DFG) Heidelberg University has been successful with six applications for grants to fund major, internationally visible research consortia.

Progress expands bioethical boundaries

Bioethics is a rich and continually evolving field. In the broadest sense, bioethics relates to the way human individuals treat any form of life. The issue of whether human beings have the right to do whatever they want goes way back. Rapid progress in genetic engineering and cell biology means that it is necessary to look at certain issues in a new way and recognise that not everything that is technically feasible should actually be carried out.
