“…Hormones and growth factors such as the insulin-like growth factor (IGF), platelet-derived growth factor (PDGF) or EGF are the major regulators of ERK 1/2, but it also may be activated by cytokines, proteins of extracellular matrix such as fibronectin and collagen, glucose and ROS [41,42,110]. Although activation of ERK 1/2 has been mainly associated with cell proliferation and differentiation, there are studies indicating their potential involvement in hepatic I-R injury [7,46,50,80,95,97,98,99,100,111,112,113,114] (Table 5 and Table 6, Figure 1). However, a specific activator or inhibitor of ERK has not been used in any of these studies.…”
