Furthermore , these observed effects were partially abolished by SB - 203580 ( a p38 MAPK inhibitor ) , rather than by either U - 0126 ( an ERK inhibitor ) or SP - 600125 ( a JNK inhibitor ) , suggesting that clopidogrel - induced disruption in the gastric epithelial cells is mediated by the p38 MAPK pathway .
