Knockdown of endogenous Sp1 decreased the mRNA expression and protein level of ERCC6 and Sp1 in 239T cells. a Detection of ERCC6 and Sp1 mRNA expression by qRT-PCR. Values represent mean ± SD. *P < 0.01. b Protein level of ERCC6 and Sp1 was examined by Western blot analysis. Results are presented as mean ± SD. c Relative ERCC6 protein level to GAPDH is presented as mean ± SD. *P < 0.01
