Abstract
1. The contractile actions of vanadate (VO4) and pervanadate (PV, peroxide(s) of vanadate) were studied in rat gastric longitudinal muscle strips and in aortic rings. The roles of extracellular sodium and calcium were evaluated and the potential effects of nerve-released agonists were considered. The possibility that these responses were due to the potentiation of tyrosine kinase activity, as a result of PV-mediated tyrosine phosphatase inhibition was explored with the use of tyrosine kinase inhibitors (genistein, tyrphostin) and by Western blot analysis of phosphotyrosyl proteins in PV-treated tissues. The ability of PV to mimic the action of the tyrosine kinase receptor-associated agonist, epidermal growth factor-urogastrone (EGF-Uro), in the gastric preparation was also studied. 2. PV caused concentration-dependent contractions in both gastric and aorta-derived tissues, with a potency that was 1 to 2 orders of magnitude greater than that of VO4. 3. Although repeated exposure of gastric and aortic tissues to a fixed concentration of VO4 caused reproducible contractions in both tissues, repeated exposure of gastric tissue to PV caused an increased contractile response plateauing after 3 exposures. In contrast, a single exposure of aortic tissue to PV (20 microM) caused a prolonged desensitization of the tissue to the subsequent contractile actions of PV or other agonists. 4. The contractile responses to PV were unaffected in both preparations by tetrodotoxin, atropine, yohimbine and phenoxybenzamine; and in the aortic preparation, the responses to VO4 and PV were the same in the presence or absence of a functional endothelium.(ABSTRACT TRUNCATED AT 250 WORDS)
