J Clin Invest 2022;132(4):e153752 doi: 10.1172/JCI153752Brief summary: Using rodent and primate models, this study shows a classical endocrine feedback loop, where bone-derived osteocalcin enhances adrenal steroidogenesis, and the inactivation of osteocalcin signalling impairs adrenal growth and steroidogenesis.This study provides important evidence on the existence of the bo...

In Brief: This case report describes the successful use of RZ358, a novel human anti–insulin receptor monoclonal antibody therapy, in a patient with severe, refractory hypoglycaemia due to metastatic insulinoma.The tumour and resulting severe hypoglycaemia had been resistant to treatments with octreotide, lutetium Lu 177 dotatate radionuclide, diazoxide, everolimus, dexamethasone, pasireotide, and glucagon – and the patient, a 55-year old man w...

Proc Natl Acad Sci USA. 2020 Jun 16;117(24):13680–13688. 10.1073/pnas.1921676117. PMID: 32493750.On the search for a genetic cause for 46,XX virilization due to testicular (TDSD) or ovotesticular DSD (OTDSD), 78 individuals were studied by whole exome sequencing. In 7 cases, heterozygous de novo variants were found in the 4th zinc finger (ZF4) of the Wilms tumor 1 gene (<em...

In Brief: The authors describe a wide range of studies. Firstly, observational studies showed that circulating taurine concentrations decline with age in mice, monkeys, and humans – and in the latter, low taurine was associated with metabolic disease (abdominal fat, blood pressure, Type 2 diabetes). They then gave oral taurine to mice throughout their lives and showed that this increased lifespan by 10–12% and improved functional outcomes of almost all tissues studie...
