Fig. 4: Intraperitoneal glucose tolerance test (IPGTT) and insulin concentration of mice.

A The blood glucose levels of mice in IPGTT. B 18 h of fasting blood glucose levels in mice. C The serum insulin levels were measured, and D the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated (n = 5–7 per group). Results are expressed as the mean ± standard error of the mean (SEM). One-way ANOVA was used for multiple comparisons. #p < 0.05 vs. the control; ##p < 0.01 vs. the control; *p < 0.05 vs. the WD + CCl4 group; **p < 0.01 vs. the WD + CCl4 group.
