We investigated changes of phosphorylation state of connexin43 (Cx43) in hypertrophied rat right ventricles secondary to pulmonary hypertension induced by monocrotaline (MCT) using western blot analysis. In normal right ventricular myocardium, most of Cx43 was phosphorylated. In hypertrophied ventricles of MCT-treated rats, the non-phosphorylated isoform of Cx43 increased and the phosphorylated isoform of Cx43 decreased with no significant a change in the total amount of Cx43 protein. These results suggest that dephosphorylation of Cx43 in MCT-induced right ventricular hypertrophy may be involved in gap junction disorganization., 国立情報学研究所で電子化したコンテンツを使用している。}, pages = {106--108}, title = {Dephosphorylation of Connexin43 Associated with Ventricular Hypertrophy}, volume = {46}, year = {2002} }
