Diabetic incidence, blood glucose levels (BGLs), glucose tolerance tests (GTT) and insulin tolerance tests (ITT) in female non-obese diabetic (NOD) mice on the soy-based diet. (A) Type 1 diabetes (T1D) incidence (N = 5–6). Blood glucose ≥250 mg/dL was considered diabetic. (B) Time course of non-fasting BGLs. Also shown are GTTs after 1 month (C) and 2 months (D) of BPS exposure (N = 5–6), and ITTs after 1 month (E; N = 5–6) and 2 month (F; N = 3–5) of BPS exposure. The values are presented as mean ± SEM. *, p < 0.05 for 30 μg/kg BPS vs. vehicle (VHF) control group. #, p < 0.05 for 3 μg/kg BPS vs. VHF group. †, p < 0.05 for 300 μg/kg BPS vs. VHF group.
