Modulation of insulin homeostasis in iNOS-/- mice by nitrite, metformin, pioglitazone, and a combination of ampicillin-neomycin. (A) Fasting serum insulin levels; Indices of insulin resistance (B) HOMA-IR and insulin sensitivity (C) QUCIKI (n = 6–12). (D) Relative tissue weights (n = 4–12). Data are represented as mean ± SD. *** p < 0.001 and **** p < 0.0001 vs. WT; # p < 0.05, ## p < 0.01, ### p < 0.001 and #### p < 0.0001 vs. iNOS-/-.
