Inhibitors of Phosphoinositide 3‐Kinase, LY294002 and Wortmannin, Affect Sperm Capacitation and Associated Phosphorylation of Proteins Differently: Ca2+‐Dependent Divergences

Abstract excerpt

Sperm capacitation is regulated by multiple pathways that also control sperm motility and tyrosine (Tyr) phosphorylation of several sperm proteins. Among the reported pathways, phosphoinositide 3-kinase (PI3K) signaling and its role in modulating sperm postejaculatory changes and motility remain elusive. It was shown that wortmannin, a selective inhibitor of PI3K, prevents human sperm acrosome reaction. Using...
