In Brief: These authors studied liver-specific SIRT2 knockout mice to examine how loss of hepatocyte SIRT2 (Sirtuin 2) prevents bone loss in aged mice. Hepatocyte SIRT2 deficiency led to upregulation of Leucine rich α2 glycoprotein (LRG1) in hepatocyte-derived small extracellular vesicles (sEVs) which inhibited osteoclastogenesis in bone marrow.Commentary: Liver-bone communication has been implicated in bone homeostasis. P...

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...

Brief Summary: This multicenter, international, retrospective study evaluated fertility potential and gonadal function in 326 adolescent and young adult cancer survivors. Risk factors for impairment included hematopoietic stem cell transplantation (HCT) conditioning regimen (myeloablative conditioning, MAC vs reduced-intensity conditioning, RIC).The prevalence of gonadal hormone failure in females was 55.3% (defined as FSH >30 mIU/mL with an estradio...
