Association between nuclear expression of retinoic acid receptor alpha and beta and clinicopathological features and prognosis of advanced non-small cell lung cancer

Background Transcription factors such as retinoic acid receptor alpha (RARα) and beta (RARβ) and Yin Yang 1 (YY1) are associated with the progression of non-small cell lung cancer (NSCLC). In particular, a lack of RARβ expression is associated with NSCLC development. The aim of this study was to analyze the expression of RARα, RARβ and YY1 and their relationship with prognosis in patients with advanced NSCLC.
