dc.description.abstract | We investigated the alteration of signal transduction after acute esophagitis in cat lower esophageal sphincter (LES). Acute esophagitis (AE) was induced by perfusion with 0.1N HCl at a rate of 1 ml/min for 45 min over three consecutive days. Acetylcholine (ACh)-induced contraction was inhibited by M3much greater than M1 or M2 antagonists in normal LES. In AE, inhibition by M2 antagonists increased significantly, so that contraction was inhibited by M3> M2> M1 antagonists and the expression of M2 and M3 receptors were increased when compared to normal LES. In normal cells, ACh-induced contractions were antagonized by antibody against G(q/11) and the phosphatidylinositol-specific phospholipase C (PI-PLC) antagonist, U73122. The phosphatidylcholine-specific phospholipase C (PC-PLC) inhibitor, D609, or the phospholipase D inhibitor, propranolol had no effects on contraction in normal LES. However, in AE, G(q/11), and G(i3) antibodies reduced ACh-induced contraction and U73122, propranolol and D609 also reduced the contraction. In AE, we found that the expressions of G protein subtypes were increased but the expression of PLCbeta1, and PLCgamma1 were decreased when compared to normal LES. In conclusion, experimental esophagitis may alter the signal transduction by ACh in LES. ACh-induced contraction is mediated by M3 receptor, G(q/11) and PI-PLC in normal LES. However, in AE, the contractions are mediated by M2, M3 receptor, Gq/11 and G(i3). PC-PLC and PLD as PI-PLC are also involved in ACh-induced cell contraction in AE. (C) 2004 Elsevier Inc.
