Hepatic IRA expression alleviates
intrahepatic lipid accumulation. (A) Representative images of Oil Red O staining to study hepatic-specific lipid accumulation. Image magnification: ×20. (B) Quantification of hepatic-specific lipid content in STD (n=5), HFD (n=6), HFD-GFP (n=5), HFD-IRA (n=6) and HFD-IRB (n=6) mice. (C) Circulating cholesterol levels (mg/dl) in STD (n=5), HFD (n=8), HFD-GFP (n=6), HFD-IRA (n=8) and HFD-IRB (n=6) mice. (D) Circulating triglyceride levels (mg/dl) in STD (n=5), HFD (n=8), HFD-GFP (n=6), HFD-IRA (n=8) and HFD-IRB (n=7) mice. Results are expressed as mean±
s.e.m. Statistical significance was assessed by two-tailed unpaired Student's t-test [versus STD mice (*P<0.05 and **P<0.01), versus HFD mice ($$P<0.01), versus HFD-GFP mice (±P<0.05) and versus HFD-IRB mice (††P<0.01)].
