Critical role of serum response factor in pulmonary myofibroblast differentiation induced by TGF-beta.

abstract：:Infants born to heroin- and cocaine-addicted mothers have been reported to have a lower incidence of respiratory distress syndrome (RDS) compared with nonaddicted infants. However, it is not known whether these are direct drug-mediated effects or secondary phenomena. We therefore investigated the effect of opioids and...
