Role of protein kinase C alpha and cyclin D1 in the proliferation of airway smooth muscle in asthmatic rats.

Abstract

Increased expression of PKCalpha and cyclin D1 in ASM along with smooth muscle structure changes might implicate PKCalpha and cyclin D1 participation in the proliferation of ASM and contribute to the pathogenesis of asthma after repeated allergen exposure in rats. The results suggested that cyclin D1 might be downstream of PKC signal transduction pathway.
