Figure 5From: T cells cooperate with palmitic acid in induction of beta cell apoptosisPA and Sn induce RIN cell apoptosis through induction of nitric oxide production. RIN cells were cultivated without treatment (medium) or treated with Sn and/or PA and/or hemoglobin (Hb, 20 mg/ml) and/or SB202109 (40 μM). After 2 or 6 hours RIN cells were fixed before cell-based ELISA for iNOS (A). Cells were stained with DAF-FM (B, D) and AnnV/EtD-III (C) after 6 hours of cultivation. Mean values +/- SD of values obtained in three individual experiments with similar results are presented (A, C). Alternatively, plots from a representative of at least three experiments with similar data are presented (B, D). *p < 0.05 represents a statistically significant difference relative to the cultures grown in medium without additional treatment (A, C) and to the cultures treated with Hb (C).Back to article page
