Phosphorylation of p42/p44 MAPK in hPASMCs exposed to chronic hypoxic (10% O2) or normoxic conditions. Western blot analysis showing phosphorylated p42/p44 MAPK in hPASMC maintained under normoxic (−) and chronic hypoxic (+H) conditions for 14 days. In all, 10 μg protein/sample was loaded onto SDS-PAGE. Above is a representative result of three individual experiments, quantified by densitometry.
