α-cell viability upon MDC exposure. (A–F) αTC1-9 cells were treated with vehicle (DMSO) or different doses of BPA (A), TBT (B), PFOA (C), TPP (D), TCS (E), or DDE (F) for 48 h. A cocktail of the cytokines IL-1β + IFNγ (50 and 1000 U/mL, respectively) was used as a positive control. Cell viability was evaluated by MTT assay. (G–I) αTC1-9 cells were treated with vehicle (DMSO) or different doses of BPA (G), TBT (H), PFOA, TPP, TCS, or DDE (I) for 24 h. Apoptosis was evaluated using HO and PI staining. Data are shown as means ± SEM (n = 4–5 independent experiments, where each dot represents an independent experiment). * p ≤ 0.05, ** p ≤ 0.01 and *** p ≤ 0.001 vs. Vehicle. MDCs vs. Vehicle by one-way ANOVA; Cytokines vs. Vehicle by two-tailed Student’s t test.
