Fig. 2From: Investigating the mechanism by which SMAD3 induces PAX6 transcription to promote the development of non-small cell lung cancerSMAD3 knockdown decreased SMAD3 and PAX6 expression levels. a SMAD3 and PAX6 mRNA expression levels in A549 cells transfected with siRNA and normalized to GAPDH (left panel) and GUSB (right panel). b SMAD3 and PAX6 protein expression levels in A549 cells transfected with siRNA (n = 3). c SMAD3 and PAX6 mRNA expression levels in HCC827 cells transfected with siRNA normalized to GAPDH (left panel) and GUSB (right panel). d SMAD3 and PAX6 protein expression levels in HCC827 cells transfected with siRNA. Data represent the mean ± SD. *P < 0.05 and **P < 0.01 compared with the control groupBack to article page
