Fig. 4From: Transcription factor E2F1 promotes EMT by regulating ZEB2 in small cell lung cancerOther E2F family members were detected by real-time PCR when E2F1 was depleted. The expression levels of other E2F family members were examined by real-time PCR in H446-E2F1sh and H1688-E2F1si cells. The p value and error bar was calculated in 3 independent experiments. ** represents p < 0.001Back to article page
