A: The mRNA expression levels of Caspase-3, Caspase-8, and Caspase-9 were surveyed by qRT-PCR assay in C918 cells. B: Western blot assay was used to survey the protein expressions of Caspase-3, Caspase-8, and Caspase-9 in C918 cells. GAPDH served as an internal control. Quality one was applied to detect count the gray value. aP<0.05, bP<0.01, cP<0.001, compared with control.
