摘要

Retinoic acid can cause malformations of the developing nervous system. Smad signaling is involved in embryonic development. The current study investigated all-trans-retinoic acid (ATRA)-induced alteration of Smad expression in the developing neural tubes of mice. Pregnant mice were treated with a single dose of 50 mg/kg ATRA by oral gavage on embryonic day E7. Western immunoblotting was used to examine Smads proteins, particularly phosphorylated (p-) Smad1, total Smad1 and Smad6 in the neural tissue of the embryos on E8-E11 following treatment. Results showed that ATRA treatment significantly increased expression of both p-Smad1 and total Smad1, while Smad6 was decreased in neural tissues of ATRA-exposed embryos in utero from E8 to E11, a critical period for neural tube formation. Data suggest that disruption of Smad signaling may be involved in ATRA-induced neural tube defects.
