Effect of BDNF and 2-APB on cell vialibity and apoptosis in NRVMs. (A) Effect of BDNF on cell viability in hypoxia. *p<0.05 vs. hypoxia, #p<0.05 vs. 200 ng/ml BDNF, &p<0.05 vs. 200 ng/ml BDNF+Si-TRPC3 or 200 ng/ml BDNF +Si-TRPC6, n = 6 each group. (B) Effect of BDNF (200 ng/ml), 2-APB and TrkB-Fc on cell vialibity in normoxia. (C) mRNA level of TRPC3/TRPC6 in control and TRPC3/TRPC6 siRNA treated cardiomyocytes. (D) Effect of BDNF on cardiomyocytes apoptosis subject to hypoxia by TUNEL staining. Nuclei are stained in blue while apoptotic cells are stained in green, scale bar: 100 μm. (E) TUNEL positive cell (%), *p<0.05 vs. hypoxia, #p<0.05 vs. 200 ng/ml BDNF, &p<0.05 vs. 200 ng/ml BDNF+Si-TRPC3 or 200 ng/ml BDNF +Si-TRPC6, n = 5 each group.
