(A) Q-PCR analysis of mRNA expression levels of STAT3 downstream target genes, c-Myc, p21, Survivin, and Socs3. (B) Serum IL-6 levels in WT, SHPTg and FXR−/− mice at 3-, 6-, 12- and 18-month old; liver IL-6 protein levels in WT and FXR−/− mice at 3-month old. (C) Q-PCR analysis of mRNA expression levels of IL-1β and IL-6 in livers of each genotype at 3-, 6-, 12- and 18-month old. An asterisk indicates P < 0.05 and double asterisks mean P < 0.01 between WT and FXR−/− or FXR−/−/SHPTg mice.
