Downregulation of YAP in Clear Cell Renal Cell Carcinoma Contributes to Poor Prognosis and Progressive Features

Ann Clin Lab Sci. 2017 Jan;47(1):36-39.

Abstract

The goal: To investigate the expression of Yes-associated protein (YAP) in clear cell renal cell carcinoma (ccRCC) and its clinical/prognostic significance.

Procedures: The expression of YAP protein was evaluated in tissue microarray by immunohistochemistry. Correlation between YAP expression and clinicopathological characteristics of renal cell carcinoma was analyzed.

Results: Downregulation of YAP protein was observed in ccRCC samples (P=0.0311). Downregulation of YAP expression was correlated with higher T classification, higher clinical stage, and poorer differentiation (P<0.05).

Conclusions: Downregulation of YAP in clear cell renal cell carcinoma (ccRCC) may contribute to poor prognosis and progressive features.

Keywords: Clear cell renal cell carcinoma (ccRCC); Prognosis; Yes-associated protein (YAP).
