The correlation analysis between the respective gene transporters’ expression and protein abundance did not reveal strong (r > 0.6) correlations, both in the control samples as well as in the hepatitis C livers, except for positive correlation of SLCO1B3/OATP1B3, as well as negative of ABCG2/BCRP in the Child–Pugh class C livers (Table 1). This evidence concerns the gene SLCO1B3 and hepatitis C virus infection.
