Fig. 5From: Transcription factor E2F1 promotes EMT by regulating ZEB2 in small cell lung cancerE2F1 influenced the expression of EMT-related proteins. The expression levels of CDH1, CTNNB1, CDH2 and VIM were tested by real-time PCR (a), western blotting (b) and immunofluorescence (c). Because CDH1 protein was not been detected in H446 cells, we selected H1688 to detect the CDH1 expression (d). * represents p < 0.05, ** represents p < 0.001Back to article page
