Expression of Cystathionine β-synthase and Cystathionine γ-lyase in Human Pregnant Myometrium and Their Roles in the Control of Uterine Contractility

摘要

BackgroundHuman uterus undergoes distinct molecular and functional changes during pregnancy and parturition. Hydrogen sulfide (H2S) has recently been shown to play a key role in the control of smooth muscle tension. The role of endogenous H2S produced locally in the control of uterine contractility during labour is unknown.
