Expression of Smooth Muscle Calponin in Synovial Sarcoma
Purpose. Histogenesis of synovial sarcoma remains controversial and reliable molecular markers for diagnosis are necessary. Expression of basic calponin, a smooth muscle differentiation-specific actin-binding protein, was studied in synovial sarcoma.Subjects and Methods. The basic calponin gene and the gene product were analyzed by reverse transcription PCR analysis (RT-PCR) and immunohistochem...
متن کاملVascular smooth muscle calponin. A novel troponin T-like protein.
In a search for additional Ca2+ regulatory components in vascular smooth muscle, a novel troponin T-like protein was purified from bovine aorta smooth muscle. The isolated protein was separated into several isoforms on isoelectric focusing. The major isoelectric variants were focused in the pH region of 8.4 to 9.1. The protein had slightly different molecular masses in the Mr range of 35,000 on...
متن کاملSmooth-muscle calponin in mesangial cells: regulation of expression and a role in suppressing glomerulonephritis.
The basic or h1 calponin gene, which encodes an actin-binding protein involved in the regulation of smooth-muscle shortening velocity, is known to be a smooth-muscle differentiation-specific gene. It was found that basic calponin was expressed by cultured mesangial cells and localized along the actin filaments. Among the growth factors involved in the mesangial cell pathophysiology, including p...
متن کاملExpression of human smooth muscle calponin in transgenic mice revealed with a bacterial artificial chromosome.
Defining regulatory elements governing cell-restricted gene expression can be difficult because cis-elements may reside tens of kilobases away from start site(s) of transcription. Artificial chromosomes, which harbor hundreds of kilobases of genomic DNA, preserve a large sequence landscape containing most, if not all, regulatory elements controlling the expression of a particular gene. Here, we...
متن کاملRegulation of PKC Autophosphorylation by Calponin in Contractile Vascular Smooth Muscle Tissue
Protein kinase C (PKC) is a key enzyme involved in agonist-induced smooth muscle contraction. In some cases, regulatory phosphorylation of PKC is required for full activation of the enzyme. However, this issue has largely been ignored with respect to PKC-dependent regulation of contractile vascular smooth muscle (VSM) contractility. The first event in PKC regulation is a transphosphorylation by...
