Mitogen-activated protein kinases (MAPKs) are a family of central signaling molecules that respond to numerous stimuli and are known to participate in processes of cell survival and death. However, it is not clear on data for cell-type specific acti
MAPK and ERK1/2 signaling pathways in IGF-I-induced AR coactivators induction were examined. C2C12 cells were treated with 250 ng/ml of IGF-I in the presence or absence of specific inhibitors p38 MAPK (SB203580) or ERK1/2 (PD98059). Treatment of C2C
MAPK) and extracellular signal regulated kinase (ERK) 1/2, whereas it did not affect phosphorylation of c-jun N- terminal kinase (JNK). The results indicated that hesperetin regulated the LPS-induced inflammatory response by suppressing p38 MAPK and
that ASE exhibits significant anti-adipogenesis activity by downregulating the MAPK and PPARγ pathways during the differentiation of 3T3-L1 preadipocytes. Therefore, A. scoparia may be a potential source of natural products against obesity.
MAPK에 대한 초기 연구는 동물세포가 growth factor를 인식하여 signal을 세포 안으로 전달하여 mitogen을 activation 시키는 mechanism을 밝히는 과정에서 시작되었다.
세포막 안으로 Growth facrot의 signal이 전달되면, Grb2가 Sos에 bindin화고, 이는 Ras-GDP를 Ras-GTP로 바꿔준다. 이는 Raf라는 MAPKKK(MAP kinanse kinase kinase)를 phosph
