Effect of hepatic Argonaute 2 (Ago2) deficiency on glucose metabolism of diabetic obese mice. A, Body weight of liver-specific Ago2-deficiency (L-Ago2) wild-type (WT)-ob/ob (n = 16), and L-Ago2 knockout (KO)-ob/ob (n = 13) mice on normal chow (CD) from age 5 to 12 weeks. B, Food intake normalized by body weight per day of L-Ago2 WT-ob/ob (n = 21), and L-Ago2 KO-ob/ob (n = 24) mice at age 11 weeks. C, Blood glucose levels after 6 hours of fasting of L-Ago2 WT-ob/ob (n = 20) and L-Ago2 KO-ob/ob (n = 16) at age 13 weeks. D, Glucose tolerance test (GTT) and its area under the curve (AUC) analysis in L-Ago2 WT-ob/ob (n = 18) and L-Ago2 KO-ob/ob (n = 18) mice at age 7 weeks. E, Serum insulin levels after 6 hours of fasting of L-Ago2 WT-Lean (n = 3), L-Ago2 WT-ob/ob (n = 4), L-Ago2 KO-Lean (n = 3), and L-Ago2 KO-ob/ob (n = 7) mice at age 13 weeks. F, Insulin tolerance test (ITT) and its AUC analysis in L-Ago2 WT-ob/ob (n = 18) and L-Ago2 KO-ob/ob (n = 18) mice at age 9 weeks. G, Messenger RNA (mRNA) expression levels of de novo lipogenesis and gluconeogenesis in livers of L-Ago2 WT-Lean (n = 5), L-Ago2 WT-ob/ob (n = 10), L-Ago2 KO-Lean (n = 5), and L-Ago2 KO-ob/ob (n = 4) mice after overnight fasting at age 13 weeks. H, Metabolic disease–associated microRNAs (MD-miRNAs) and I, their target mRNA expression levels in livers of L-Ago2 WT-Lean (n = 5), L-Ago2 WT-ob/ob (n = 10), L-Ago2 KO-Lean (n = 5), and L-Ago2 KO-ob/ob (n = 4) mice after overnight fasting at age 13 weeks. Data are shown as mean ± SEM of group size (n). Statistical analyses were performed by unpaired 2-tailed t test for C, D, and F or by 2-way analysis of variance followed by Tukey post hoc test for E, G, H, and I. *P less than or equal to .05, **P less than or equal to .01, ***P less than or equal to .001.
