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...

To read the full abstract: Science 2019;365:386392.By genetically engineering mice, the authors deleted the enzyme dihydroceramide desaturase 1 (DES1), which normally inserts a conserved double bond into the backbone of ceramides. Ablation of DES1 from whole animals or tissue-specific deletion in the liver and/or adipose tissue resolved hepatic steatosis and insulin resistance in mice caused by leptin deficiency or obesogenic diets<p c...
