Reactivation of embryonic genes leads to muscle aging

Developmental genes and pathways strictly regulate embryogenesis. The process is strongly driven by so-called Hox-genes. Now, researchers from the Leibniz Institute on Aging (FLI) in Jena, Germany, can show that one of these ...

Mouse study links heart regeneration to telomere length

Researchers at the Spanish National Center for Cardiovascular Research have discovered that the ends of heart muscle cell chromosomes rapidly erode after birth, limiting the cells' ability to proliferate and replace damaged ...

Mini-breast grown in Petri dishes—a new tool for cancer research

The research group, led by Dr. Christina Scheel, developed an assay whereby cultured human breast epithelial cells rebuild the three-dimensional tissue architecture of the mammary gland. For this purpose, a transparent gel ...

Protein may improve liver regeneration

Researchers at UC Davis have illuminated an important distinction between mice and humans: how human livers heal. The difference centers on a protein called PPARα, which activates liver regeneration. Normally, mouse PPARα ...
