Mitogen-activated protein kinase(MAPK)signal pathway family are important signal transduction pathways, which widely exit in cells. They are able to make particular physiological responses induced by multiple extracellular signals or stimulus, such as changes of osmotic pressures, ischemic/reperfusion, inflammation and so on, that means they can mediate cell proliferation, differentiation and apoptosis. The physiological responses mediated by MAPK signal pathway make great scene to the progression and healing of eye wounds, therefore researchers may highlight the pathway in research.
