Abstract:
:Vasoactive intestinal peptide (VIP) induces phosphorylation of a basic 38,000 mol. wt protein in a human lymphoblastic cell line (Molt 4b) and a human colon carcinoma cell line (HT29). In both cell types, VIP interacts with specific high affinity receptors to activate adenylate cyclase and cAMP-dependent protein kinase. The two cell types appear to express homologous receptors with similar affinity and specificity for VIP, but the colonic epithelial cells express a greater number of receptors. HT29 colonic cells also exhibit a greater stimulation of adenylate cyclase and a higher phosphorylation index for the 38,000 mol. wt protein in response to VIP. This 38,000 mol. wt protein, which is phosphorylated in the presence of VIP, appears to be identical in both cell lines; it is phosphorylated in both lymphoblasts and colonic epithelial cells in the presence of forskolin, but not in the presence of phorbol 12-myristate 13-acetate. Phosphorylation of this 38,000 mol. wt protein may be an important step in VIP regulation of water and electrolyte secretion from colonic epithelial cells, and in VIP regulation of immunoglobulin and lymphokine secretion from lymphocytes.
