Chronic ethanol exposure induced FGF21 resistance. Quantitative RT-PCR determined relative β-klotho (A) and FGF receptor (FGFR) (B) mRNA levels in islets isolated from mice after 1–3 weeks of being gavaged with or without ethanol. (C) Increased levels of serum FGF21 levels in terminal bleed blood, determined by ELISAs, after 3 weeks of ethanol exposure. (D) Western blot, with β-actin densitometry loading control, demonstrating ethanol exposure-induced elevation of FGF21. Data are means ± SEs; *P<0.05, **P<0.01, ***P<0.001 vs. time-matched saline gavaged group (N=5 per treatment-time group).
