OxPAPC induces ERK1/2 phosphorylation.

HUVECs were treated with OxPAPC (125 μg/mL) or TNF-α (100 U/mL) for indicated times. Cells were harvested and processed for Western blotting with antibodies to phospho-ERK1/2 or nonphosphorylated ERK1/2 to check for equal loading. The data are representative of 3 independent experiments.
