丝裂原活化蛋白激酶(MAPK)ERK 1/2调节许多细胞过程,包括基因转录、增殖和分化。MAP 2Ks MEK 1/2的唯一已知底物是ERK 1/2;因此,MEK抑制剂PD 98059、U 0126和PD 0325901已成为确定ERK 1/2功能的重要工具。通过使用这些抑制剂和基因操纵MEK,我们发现ERK 1/2激活对于调节胰腺β细胞的胰岛素分泌或嗜铬细胞的肾上腺素分泌既不充分也不必要。我们发现,PD 98059和U 0126都能减少激动剂诱导的钙离子进入细胞,这与它们抑制ERK 1/2的能力无关。在解释使用这些化合物的实验结果时应谨慎。
The mitogen-activated protein kinases (MAPKs) ERK1/2 regulate numerous cellular processes including gene transcription, proliferation, and differentiation. The only known substrates of the MAP2Ks MEK1/2 are ERK1/2; thus, the MEK inhibitors PD98059, U0126, and PD0325901 have been important tools in determining the functions of ERK1/2. By using these inhibitors and genetically manipulating MEK, we find that ERK1/2 activation is neither sufficient nor necessary for regulated insulin secretion from pancreatic beta cells or epinephrine secretion from chromaffin cells. We show that both PD98059 and U0126 reduce agonist-induced calcium entry into cells independently of their ability to inhibit ERK1/2. Caution should be used when interpreting results from experiments using these compounds.
