Research: A broad-spectrum lasso peptide antibiotic targeting the bacterial ribosome Researchers at McMaster University, … Read more
Only recently has the ribosome – one of the oldest molecular machines in evolutionary terms – been recognized as an active regulator of gene expression at the level of protein biosynthesis. This is an important process for the development and function of cells, in which genetic information is converted into proteins. The final step, in … Read more
New research pinpoints faulty branched-chain amino acid (BCAA) metabolism as a driving force behind sarcopenia, highlighting a potential pathway to slow muscle deterioration and improve aging health. Study: Multi-omic Profiling of Sarcopenia Identifies Disrupted Branched-chain Amino Acid Catabolism As a Causal Mechanism and Therapeutic Target.
