Brief summary: In this in vivo study, Xia et al. demonstrate that AAV-mediated gene therapy recovers testosterone levels, restarts sexual development, restores spermatogenesis, and produces fertile offspring in a mouse model of Leydig cell failure (LCF).A null mutation in the gene encoding luteinizing hormone/choriogonadotrophin receptor (Lhcgr) causes a hereditary LCF in mice which is characterized by a reduction in testosterone levels...

Brief summary: Using in-depth multi-omics analyses of human type 1 diabetes (T1D) samples, the authors profiled gut microbial functional and metabolic alterations. The T1D microbiota showed decreased butyrate production and bile acid metabolism and increased lipopolysaccharide (LPS) biosynthesis. Fecal microbiota transplantation in animal models proved that T1D gut microflora is a causative factor in the regulation of glucose metabolism.The etiology of T...

PMID: 33619380.In brief: In this genome-wide association study, the authors were able to disentangle the mechanism that uncouples adiposity from its known cardiometabolic complications. They identified 62 genomic loci, at which the same allele is associated with both higher adiposity and lower cardiometabol...

To read the full abstract: J Clin Endocrinol Metab. 2020; 105(3): dgz145. PMID: 31665349.Prenatal treatment with glucocorticoids (GC) is used in several clinical indications. However, the long-term outcome on offspring metabolic, somatic and cognitive health has raised significant concern. In rodents, high glucocorticoid levels inhibit development of beta cells during fetal life and lead to...
