Short summary: This study describes sex differences in fetal liver-specific androgen signalling that are altered in response to maternal obesity in baboons. It reveals that livers of male fetuses favour a pro-androgenic environment in response to maternal obesity by suppressing the activity of testosterone-metabolising CYP enzymes (CYP2B6 and CYP3A) and by reducing cytoplasmic and nuclear androgen receptor (AR-45) expression. By comparison and most interestingly, there were mi...

Epigenomics. 2021 Aug;13(15):1221-1230. doi: 10.2217/epi-2021-0096. PMID: 34337972.Brief Summary: This case cohort study assessed whether epigenetic factors explain the link between gestational diabetes mellitus (GDM) and macrosomia. Epigenetic changes in the MEST gene were associated with both GDM and macrosomia.GDM leads to neonatal macrosomia and in the long-t...

Nat Commun. 2022 Feb 9;13(1):775. doi: 10.1038/s41467-022-28120-2. PMID: 35140214Brief Summary: This in vitro study identified interactions between distinct cell populations of the thyroid gland and immune cells in the context of Hashimoto thyroiditis. The authors provide important new insights into the pathological mechanism of Hashimoto thyroiditis by characterizing the stromal ...

Brief summary: In this experimental study, genome editing and in vitro pancreatic differentiation of human pluripotent stem cells (SC) were used to generate ZNT8 loss-of-function (LOF) SC-β-cells. These cells showed accelerated functional maturation, increased insulin secretion and improved resistance to metabolic stress. Transplantation of ZnT8 LOF SC-β-cells into mice with preexisting diabetes significantly improved their glucose levels.<...

Brief Summary: Artemisinins, compounds known for their antimalarial properties, suppress ovarian androgen synthesis by promoting degradation of cytochrome P450 11A1 (CYP11A1). Hence, they are a promising new approach for preventing and treating PCOS.Comment: Polycystic ovary syndrome (PCOS), characterized by hyperandrogenism, chronic anovulation, and insulin resistance, is one of the most common reproductive endocrinopathies, affecting ~8-18% of reproduc...
