English: This image shows a DNA molecule that is methylated on both strands on the center cytosine. DNA methylation plays an important role for epigenetic gene regulation in development and cancer. The picture shows the crystal structure of a short DNA helix with sequence “accgcCGgcgcc”, which is methylated on both strands at the center cytosine. The structure was taken from the Protein Data Bank (accession number 329D), rendering was performed with VMD and post-processing was done in Photoshop. (Photo credit: Wikipedia)

Researchers at the Ruhr-Universitat Bochum together with colleagues from Basel, Trier and London for the first time in the journal Translational Psychiatry report that acute stress alters DNA methylation (epigenetics). This may be the link with the fact that stress increases the risk of both mental and physical diseases. The picture in this BLOG is a DNA strand that is methylated (epigenetic).
