The smooth muscle myosin heavy chain gene exhibits smooth muscle subtype-selective modular regulation in vivo.
Previous studies in our laboratory demonstrated that the transgene consisting of the -4.2 to +11.6 kilobase (kb) region of the smooth muscle (SM) myosin heavy chain (MHC) gene was expressed in virtually all SM tissue types in vivo in transgenic mice and that the multiple CArG elements within this region were differentially required in SMC subtypes, implying that the SM-MHC gene was controlled b...
متن کاملExpression of smooth muscle and nonmuscle myosin heavy chains in cultured vascular smooth muscle cells.
We explored the hypothesis that discrepancies in the literature concerning the nature of myosin expression in cultured smooth muscle cells are due to the appearance of a new form of myosin heavy chain (MHC) in vitro. Previously, we used a very porous sodium dodecyl sulfate gel electrophoresis system to detect two MHCs in intact smooth muscles (SM1 and SM2) which differ by less than 2% in molecu...

We cloned a portion of the mouse smooth muscle myosin heavy chain (SM-MHC) cDNA and analyzed its mRNA expression in adult tissues, several cell lines, and developing mouse embryos to determine the suitability of the SM-MHC promoter as a tool for identifying smooth musclespecific transcription factors and to define the spatial and temporal pattern of smooth muscle differentiation during mouse de...
متن کاملThe Effect of Adiponectin on Matrix Metalloproteinase-9 (MMP-9) in Vascular Smooth Muscle Cells
Background & Aims: Atherosclerosis is a major cause of morbidity and mortality. Adiponectin reducesthe risk of heart disease, and matrix metalloproteinase-9 (MMP-9) is involved in the formation and development of atherosclerotic plaque. The aim of this study was the investigation of the effect of adiponectin on MMP-9 gene expression. It seems this hormone can reduce the risk of atherosclerosis ...
