VK Yadav , JM Berger , P Singh , P Nagarajan , G Karsenty

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: 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...
