BackgroundCarcinoids are neuroendocrine (NE) tumors with limited treatment options. Raf-1 pathway activation has been shown to suppress hormone production in carcinoid cells. We investigated a novel treatment for carcinoid cell growth based on pharmacologic Raf-1 activation using the compound tautomycin (TTY).MethodsHuman carcinoid cells were treated with TTY for 48 hours. Western blot analysis was used to demonstrate Raf-1 pathway activation by phosphorylation of ERK1/2 and to determine the effect...
