compound C | i.e. AMPKi or 6-[4-(2-piperidin-1-yl-ethoxy)-phenyl]-3-pyridin-4-yl-pyrrazolo[1,5-a]-pyrimidine, a specific inhibitor of AMPK, largely impairs the activation of p38 MAPK upon UV radiation | Homo sapiens | |
additional information | activation of p38 in response to UV or H2O2 is inhibited in AMPKalpha siRNA-treated HaCaT cells, EGFR inhibitor PD 153035 and AG 1478 inhibit UV-induced AMPK and LKB1 activation | Homo sapiens |
