Figure 2. Expression of PRGs in HCC, paracancerous tissue and paired normal liver tissue. (A) Clinical features of three HCC patients for validating PRG expression. (B) qRT-PCR of HCC, paracancerous tissue, and paired normal liver tissue. mRNA quantification of APIP, CASP3, CASP4, CASP6, CASP8, NOD1, NOD2, PELO, CASP9, DPP9, and NLRP1 was normalized to GAPDH. (C) mRNA ratios between HCC and paracancerous tissue and paired normal liver tissue within the same patients. Each group consists of three independent replicates. Data are presented as mean ± SEM.*P < 0.05; **P < 0.01.
