Pannexin-1 protein expression is decreased at pathological pH. Representative immunoblot analysis (a) of P2X7, P2X4 and pannexin-1 at three different pH levels (7.4, 6.8 and 6.5). Densitometric analysis corresponds to P2X7 (b) and pannexin-1 (Panx1) (c). β-actin was used as an internal standard for protein loading control. Data presented as mean+/−SEM. **p < 0.05 compared to 6.8 and *p < 0.05 compared to 7.4. N = 6 wells per group
