Nat Commun. 2020;11:4807. doi: 10.1038/s41467-020-18497-3.This interesting paper illustrates the potential of machine learning to improve the sensitivity and specificity of routine techniques in clinical practice if large cohorts for training and validation of models are used. Yu et al. present a transfer learning model (machine learning approach to solve research problems by r...

Brief summary: Genome-wide small hairpin RNA screening revealed a specialized role for the protein phospholipase D6 (PLD6) located at and highly expressed in the outer mitochondrial membrane of cells in steroidogenic organs. Here PLD6 promotes the entrance of LDL/LDLR complex into the mitochondria where LDL-carried cholesterol is released for steroid hormone biosynthesis.Thereby the mitochondrial redox-sensitive CISD2 protein was found to support the trafficking of the LDL/LDL...

Physical activity can reverse age-dependent decline in skeletal muscle, preventing osteopor...
