Values are mean±SD (n=6).

Different superscripts (a,b) within a row indicate significant differences among groups (P <0.05).

ΔC_T, mean of C_T value for the target gene–mean of C_T value for β-actin; 2^−ΔΔT, differential gene expression in the target sample compared to the normal sample counterpart.
