1 PACAP-27 tyrosine phosphorylates mitogen activated protein kinase and increases VEGF mRNAs in human lung cancer cells. Tyrosine adenylate cyclase activating polypeptide 1 Homo sapiens
2 The effects of pituitary adenylate cyclase activating polypeptide (PACAP) on human lung cancer cell line NCI-1299 mitogen activated protein kinase (MAPK) tyrosine phosphorylation and vascular endothelial cell growth factor (VEGF) expression were investigated. Tyrosine adenylate cyclase activating polypeptide 1 Homo sapiens
3 PACAP-27 (100 nM) increased MAPK tyrosine phosphorylation 3-fold, 5 min after addition to NCI-H1299 cells. Tyrosine adenylate cyclase activating polypeptide 1 Homo sapiens
4 PACAP caused tyrosine phosphorylation in a concentration-dependent manner being half-maximal at 10 nM PACAP-27. Tyrosine adenylate cyclase activating polypeptide 1 Homo sapiens
5 PACAP caused tyrosine phosphorylation in a concentration-dependent manner being half-maximal at 10 nM PACAP-27. Tyrosine adenylate cyclase activating polypeptide 1 Homo sapiens
6 PACAP-27 or PACAP-38 (100 nM) but not PACAP28-38 or VIP caused increased MAPK tyrosine phosphorylation using NCI-H1299 cells. Tyrosine adenylate cyclase activating polypeptide 1 Homo sapiens
7 Also, the increase in MAPK tyrosine phosphorylation caused by PACAP-27 was totally inhibited by 10 microM PACAP(6-38), a PAC(1) receptor antagonist or 10 microM PD98059, a MAPKK inhibitor. Tyrosine adenylate cyclase activating polypeptide 1 Homo sapiens
