A: qRT-PCR assay was applied to detect the mRNA expression levels of Bax, Bcl-2, and Bcl-XL in C918 cells. B: The protein expressions of Bax, Bcl-2, and Bcl-XL were detected by Western blot assays in C918 cells. Quality one was applied to detect count the gray value. aP<0.05, bP<0.01, cP<0.001, compared with control.
