Vitamins Modulate the Expression of Antioxidant Genes in Progesterone-Treated Pancreatic β Cells: Perspectives for Gestational Diabetes Management

Figure 6

Expression of Prdx4 in progesterone-treated RINm5F cells, in the presence of antioxidants. After preincubation with 40 μM vitamin E (a) or 50 μM vitamin C (b) for 2 h, cells were incubated, for 6 or 24 h, with 0.1, 1.0, or 100 μM progesterone. Data are presented as means ± SEM of three experiments in duplicates. indicates difference compared to control. indicates difference between the incubation time points, for the same progesterone concentration. $ indicates difference in comparison to the treatment without antioxidants (ρ < 0.05). PG: progesterone; Vit E: vitamin E; Vit C: vitamin C.
