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...

To read the full abstract: Science 2018;361:76–81.The tuberal nucleus (TN) is a hypothalamic region which is well described in humans but remains poorly defined in rodents. In this paper, the authors demonstrated by specific and sophisticated techniques the role of somatostatin expressing TN (TNSST) neurons in the control of food intake in mice. Interestingly, their resul...

To read the full abstract: Science 2018;360:1087-1092During the Cardiovascular Risk Survey in western China, a Kazakh family with inherited low levels of LDL-C was identified. The Kazakhs are mainly descendent from the Turkic and medieval Mongol peoples, they live in isolated regions and usually marry within their own ethnic group. They exhibit often unique differences in single nucleotide vari...
