1997. SPK1, however, not SPK2, blocks VEGF-induced deposition of Ras-GTP and phospho-ERK in T24 cells. As opposed to EGF arousal, VEGF arousal of ERK1/2 Bacitracin phosphorylation was unaffected by dominant-negative Ras-N17. Raf kinase inhibition obstructed both VEGF- and EGF-stimulated deposition of phospho-ERK1/2. Inhibition of SPK by pharmacological inhibitors, a dominant-negative SPK mutant, or siRNA that…
