Quantification of COL18A1 mRNA expression by real-time PCR.
GAPDH was used as an internal control gene. Final abundance figures were adjusted to yield an arbitrary value of 1 for HCC patients. Each experiment was performed in triplicate assay. Data are means±SD. A. COL18A1 mRNA expression in HCC, CHB, and healthy individuals. B. COL18A1 mRNA expression in CHB patients, among different genotypes of rs7499.
