Effect of PKC inhibitor on DHPG-stimulated Cx43 and ERK1/2 phosphorylation response and GJIC inhibition. Cells were treated with the PKC inhibitor GF109203X (different concentrations indicated) for 30 min prior to DHPG (100 lM, 15 min) treatment. a Representative immunoblots with an anti-Cx43 antibody are shown. b Representative immunoblots with a phospho-specific antibody recognizing the dually phosphorylated form of ERK1/2 (Thr202/Tyr204) and an antibody recognizing total ERK1/2 are shown. Quantitative analysis of the Cx43-P2/Cx43-P0?1 ratio and the phospho-ERK1/2 (p-ERK1/2)/total-ERK1/2 (t-ERK1/2) ratio are shown below the representative immunoblots, respectively. C Cells were incubated without (a) or with 100 lM DHPG (b) or with 100 μM DHPG in combination with 10 μM GF109203X (c) and scrape loaded (9100). d Cells were exposed to GF109203X (different concentrations indicated) alone (filled square) or 100 μM DHPG and GF109203X (filled diamond) prior to measurement of GJIC by scrape loading. Data are shown as mean ± SEM for three separate experiments performed in triplicate (*p<0.05 vs. NC, n = 3, +GF109203X for 0.1, 1, 5 or 10 μM) |
