Combined control of the fibroblast contractile program by YAP and TAZ.

ABSTRACT: Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) are transcription cofactors implicated in the contractile and profibrotic activation of fibroblasts. Fibroblast contractile function is important in alveologenesis and in lung wound healing and fibrosis. As paralogs, YAP and TAZ may have independent or redundant roles in regulating transcriptional programs and contractile function. Using IMR-90 lung fibroblasts, microarray analysis, and traction microscopy, we tested whether independent YAP or TAZ knockdown alone was sufficient to limit transcriptional activation and contraction in vitro. Our results demonstrate limited effects of knockdown of either YAP or TAZ alone, with more robust transcriptional and functional effects observed with combined knock
