Ethanol inhibition of undifferentiated rat neural progenitor cell replication can be prevented by chlorogenic acid via the NFATc4/CSE signaling pathway.

Background: Prenatal ethanol exposure hinders oxidative stress-mediated neuroblast/neural progenitor cell proliferation by inhibiting G1-S transition, a process vital to neocortical development. We previously showed that ethanol elicits this redox imbalance by repressing cystathionine γ-lyase (CSE), the rate-limiting enzyme in the transsulfuration pathway in fetal brain and cultured cerebral cortical neurons. However, the mechanism by which ethanol impacts the CSE pathway in proliferating neuroblasts is not known.
