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...

Abstract: Nature. 2019 Mar;567(7747):234–238.In brief: In this article, the authors present evidence that the murine epiphyseal growth plate develops a postnatal stem cell niche with monoclonal properties, that are able to self-renew. They thereby challenge the concept of a continous depletion of progenitor cells as a limiting factor for bone growth.<p class="abste...
