Forkhead box M1 (FOXM1), a Forkhead family transcription factor, is often overexpressed in a variety of human cancers, including AML and strongly associated with therapy resistance and unfavourable outcomes. In AML with NPM1 mutations NPM1/FOXM1 complex sequesters FOXM1 in the cytoplasm and confers favourable treatment outcomes for AML patients, because of FOXM1 inactivation. Inhibition of FOXM1 in AML cell lines and animal models of AML sensitizes AML cells to the Bcl2-inhibitor, venetoclax.

Follicular fluid-derived meiosis-activating sterol (FF-MAS), an intermediate in the cholesterol biosynthesis pathway, plays a crucial role in the meiotic resumption of mammalian oocytes. Maintaining a high concentration of FF-MAS in vitro is challenging; therefore, AY9944 A-7, an inhibitor of Δ14-reductase [which converts FF-MAS to testis meiosis-activating sterol (T-MAS)] and Δ7-reductase (which converts T-MAS to cholesterol), has been used to enhance oocyte maturation. This study examined the effects of various concentrations (0, 10, 20, and 40 μM) of AY9944 A-7 on porcine oocyte maturation and subsequent embryo development.
