Effect of GSNO, HIF-1α inhibitor 2-ME, and denitrosylating agent DDT on the expression of VEGF and BDNF in endothelial (bEnd3) cells. GSNO treatment increased the mRNA expression levels of VEGF and BDNF in a dose dependent manner (A). Pretreatment (2 h) with 2-ME (5 μM) or DDT (200 μM) reversed the effect of GSNO on the expression levels of VEGF and BDNF (C). The expression of VEGF and BDNF was determined at 24 h using RT-PCR and normalized against β-actin. Under the described experimental conditions, cell viability was assayed using LDH release assay (B, D), showing no significant cell death. Data are presented as mean +SD. n=5. ***p<0.001, *p<0.05 vs. Untreated, +++p<0.001 vs. GSNO.
