They are underestimated genetic control elements: it is known that changes in the genome can trigger diabetes.

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.

Certain developmental signals play a significant role in maintaining our genetic blueprints. They prevent alterations in the genome, known as mosaicism. The underlying biological mechanism helps the DNA to produce an identical copy of itself during cell division using the original genetic blueprint. However, it can also contribute to genomic mosaicism during nerve cell development.

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.

Invasive infections such as sepsis require immediate and targeted treatment. Experts from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and group partners have succeeded in establishing a reconceptualized detection principle that can make a crucial contribution to saving lives through fast, ultra-accurate pathogen identification.
