Differential regulation of tropomyosin isoform organization and gene expression in response to altered actin gene expression
Phenotypically altered C2 myoblast cells, generated by the stable transfection of human nonmuscle actin genes (Schevzov, G., C. Lloyd, and P. Gunning. 1992. J. Cell Biol. 117:775-786), exhibit a differential pattern of tropomyosin cellular organization and isoform gene expression. The beta-actin transfectants displaying a threefold increase in the cell surface area, showed no significant change...
متن کاملMonoclonal antibodies against muscle actin isoforms: epitope identification and analysis of isoform expression by immunoblot
Higher vertebrates express six different highly conserved actin isoforms that can be classified in three subgroups: 1) sarcomeric actins, α-skeletal (α-SKA) and α-cardiac (α-CAA), 2) smooth muscle actins (SMAs), α-SMA and γ-SMA, and 3) cytoplasmic actins (CYAs), β-CYA and γ-CYA. The variations among isoactins, in each subgroup, are due to 3-4 amino acid differences located in their acetylated N...
متن کاملModulation of actin isoform expression in cultured arterial smooth muscle cells by heparin and culture conditions.
Heparin inhibits arterial smooth muscle cell (SMC) proliferation in vivo and in vitro; moreover, it reinduces the expression of alpha-smooth muscle (SM) actin (an accepted marker of SMC differentiation) in SMCs of the intimal thickening that develops after experimentally induced endothelial lesions. We have investigated the effect of heparin on the proliferation and actin isoform expression in ...
متن کاملSimulation of EMG in pathological situations.
OBJECTIVE A mathematical model for simulation of the EMG from a muscle with its motor units is used. The study aims at correlating EMG findings (single-fiber EMG and concentric-needle EMG) with various induced morphological changes. METHODS Reinnervation has been simulated by removing motor units randomly followed by a complete reinnervation from adjacent surviving motor units. Fibre type gro...
متن کاملThe Actin Gene Family: Function Follows Isoform
Although actin is often thought of as a single protein, in mammals it actually consists of six different isoforms encoded by separate genes. Each isoform is remarkably similar to every other isoform, with only slight variations in amino acid sequence. Nevertheless, recent work indicates that actin isoforms carry out unique cellular functions. Here, we review evidence drawn from localization stu...
