Abstract

PURPOSE: Rapamycin has antiproliferative and antifibrogenic effects in vitro and in vivo. The purpose of this study was to evaluate the effects of rapamycin on transforming growth factor (TGF) beta 1 induced myofibroblast differentiation (alpha smooth-muscle actin [SMA]), extracellular matrix production, and collagen contraction in nasal polyp-derived fibroblasts (NPDF). The underlying molecular mechanisms of rapamycin were also determined in NPDFs.
