Résumé :

Injection of chicken gizzard actin into BALB/c mice resulted in the isolation of a smooth muscle-specific monoclonal antibody designated CGA7. When assayed on methanol-Carnoy's fixed, paraffin-embedded tissue, it bound to smooth muscle cells and myoepithelial cells, but failed to decorate striated muscle, endothelium, connective tissue, epithelium, or nerve. CGA7 recognized microfilament bundles in early passage cultures of rat aortic smooth muscle cells and human leiomyosarcoma cells but did not react with human fibroblasts. In Western blot experiments, CGA7 detected actin from chicken gizzard and monkey ileum, but not skeletal muscle or fibroblast actin. Immunoblots performed on two-dimensional gels demonstrated that CGA7 recognizes gamma-actin from chicken gizzard and alpha- and gamma-actin from rat colon muscularis. This antibody was an excellent tissue-specific smooth muscle marker.

Résumé :

In this study, the expression of smooth muscle actin and myosin was examined in cultures of rat tracheal smooth muscle cells. Protein and mRNA analyses demonstrated that these cells express α- and γ-smooth muscle actin and smooth muscle myosin and nonmuscle myosin-B heavy chains. The expression of the smooth muscle specific actin and myosin isoforms was regulated in the same direction when growth conditions were changed. Thus, at confluency in 1 or 10% serum-containing medium as well as for low-density cells (50–60% confluent) deprived of serum, the expression of the smooth muscle forms of actin and myosin was relatively high. Conversely, in rapidly proliferating cultures at low density in 10% serum, smooth muscle contractile protein expression was low. The expression of nonmuscle myosin-B mRNA and protein was more stable and was upregulated only to a small degree in growing cells. Our results provide new insight into the molecular basis of differentiation and contractile function in airway smooth muscle cells.

Résumé :

Muscle tissues are classically divided into two major types, depending on the presence or absence of striations. In striated muscles, the actin filaments are anchored at Z-lines and the myosin and actin filaments are in register, whereas in smooth muscles, the actin filaments are attached to dense bodies and the myosin and actin filaments are out of register. The structure of the filaments in smooth muscles is also different from that in striated muscles. Here we have studied the structure of myosin filaments from the smooth muscles of the human parasite Schistosoma mansoni. We find, surprisingly, that they are indistinguishable from those in an arthropod striated muscle. This structural similarity is supported by sequence comparison between the schistosome myosin II heavy chain and known striated muscle myosins. In contrast, the actin filaments of schistosomes are similar to those of smooth muscles, lacking troponin-dependent regulation. We conclude that schistosome muscles are hybrids, containing striated muscle-like myosin filaments and smooth muscle-like actin filaments in a smooth muscle architecture. This surprising finding has broad significance for understanding how muscles are built and how they evolved, and challenges the paradigm that smooth and striated muscles always have distinctly different components.

Résumé :

A monoclonal antibody (anti-alpha sm-1) recognizing exclusively alpha-smooth muscle actin was selected and characterized after immunization of BALB/c mice with the NH2-terminal synthetic decapeptide of alpha-smooth muscle actin coupled to keyhole limpet hemocyanin. Anti-alpha sm-1 helped in distinguishing smooth muscle cells from fibroblasts in mixed cultures such as rat dermal fibroblasts and chicken embryo fibroblasts. In the aortic media, it recognized a hitherto unknown population of cells negative for alpha-smooth muscle actin and for desmin. In 5-d-old rats, this population is about half of the medial cells and becomes only 8 +/- 5% in 6-wk-old animals. In cultures of rat aortic media SMCs, there is a progressive increase of this cell population together with a progressive decrease in the number of alpha-smooth muscle actin-containing stress fibers per cell. Double immunofluorescent studies carried out with anti-alpha sm-1 and anti-desmin antibodies in several organs revealed a heterogeneity of stromal cells. Desmin-negative, alpha-smooth muscle actin-positive cells were found in the rat intestinal muscularis mucosae and in the dermis around hair follicles. Moreover, desmin-positive, alpha-smooth muscle actin-negative cells were identified in the intestinal submucosa, rat testis interstitium, and uterine stroma. alpha-Smooth muscle actin was also found in myoepithelial cells of mammary and salivary glands, which are known to express cytokeratins. Finally, alpha-smooth muscle actin is present in stromal cells of mammary carcinomas, previously considered fibroblastic in nature. Thus, anti-alpha sm-1 antibody appears to be a powerful probe in the study of smooth muscle differentiation in normal and pathological conditions.

Résumé :

Evidence is accumulating to suggest that actin filament remodeling is critical for smooth muscle contraction, which implicates actin filament ends as important sites for regulation of contraction. Tropomodulin (Tmod) and smooth muscle leiomodin (SM-Lmod) have been found in many tissues containing smooth muscle by protein immunoblot and immunofluorescence microscopy. Both proteins cofractionate with tropomyosin in the Triton-insoluble cytoskeleton of rabbit stomach smooth muscle and are solubilized by high salt. SM-Lmod binds muscle tropomyosin, a biochemical activity characteristic of Tmod proteins. SM-Lmod staining is present along the length of actin filaments in rat intestinal smooth muscle, while Tmod stains in a punctate pattern distinct from that of actin filaments or the dense body marker α-actinin. After smooth muscle is hypercontracted by treatment with 10 mM Ca2+, both SM-Lmod and Tmod are found near α-actinin at the periphery of actin-rich contraction bands. These data suggest that SM-Lmod is a novel component of the smooth muscle actin cytoskeleton and, furthermore, that the pointed ends of actin filaments in smooth muscle may be capped by Tmod in localized clusters.

Résumé :

Differentiation of muscle cells is characterized morphologically by the acquisition of contractile filaments and characteristic shape changes, and on the molecular level by induction of the expression of several genes, including those for the muscle-specific alpha-actin isoforms. IFN-gamma is an inhibitor of proliferation for several cells, including vascular smooth muscle, and is also an inducer of differentiated properties for several hematopoietic cells. We have therefore investigated whether IFN-gamma affects the expression of alpha-smooth muscle actin in cultured arterial smooth muscle cells. Cells exposed to IFN-gamma show a reduction of alpha-smooth muscle actin-containing stress fibers, as detected by immunofluorescence. The effect was observed in all phases of the cell cycle, and was caused by a reduction of the synthesis of alpha-smooth muscle actin protein as revealed by two-dimensional electrophoretic analysis of actin isoforms. RNA hybridization using a cRNA probe that hybridizes to all actin mRNAs showed that IFN-gamma-treated cells have a reduced content of the 1.7-kb mRNA that codes for alpha-smooth muscle actin, and to a lesser extent, also of the 2.1-kb mRNA encoding the beta and gamma-cytoplasmic actins. The reduction of alpha-smooth muscle actin mRNA was confirmed using an alpha-smooth muscle actin-specific cRNA probe. The reduction of alpha-smooth muscle actin mRNA occurs within 12 h, and is dependent on protein synthesis, since cycloheximide treatment reversed the effect. The inhibition of this mRNA species was dose dependent, and detectable by RNA hybridization at a dose of 50 U/ml IFN-gamma. These results suggest that the differentiation of arterial smooth muscle cells is not necessarily coupled to an inhibition of cellular proliferation. Instead, IFN-gamma may regulate the expression of several genes that control both proliferation and expression of differentiation markers.

Résumé :

Vascular smooth muscle cells (VSMC) constitute an important component of blood vessels and are primarily responsible for vessel contraction. In vascular disorders such as hypertension and atherosclerosis as well as pregnancy and exercise, VSMC demonstrate increased capacity to proliferate and migrate, resulting in vascular remodelling. The actin cytoskeleton is an important component of vascular contractility and is also essential for proliferation and migration of VSMC. Vasoactive agonists such as Endothelin-1 (ET-1) and Noradrenaline (NA), have been shown to mediate VSMC contraction through changes in actin cytoskeleton and focal adhesion (FA) remodelling, and have also been reported to cause VSMC migration in the appropriate setting. The aim of this study was to investigate the signalling mechanisms responsible for FA dependent actin cytoskeleton remodelling of VSMC in response to ET-1 and NA, with a special focus on Hydrogen peroxide-inducible clone 5 (Hic-5). The latter is a FA protein shown to regulate actin cytoskeleton dynamics in small arteries in response to Noradrenaline (NA) and the response of VSMC to arterial injury and abdominal aortic aneurysm. We have shown that Src-dependent tyrosine phosphorylation of Hic-5 regulated its subcellular localisation in mouse embryonic fibroblasts and VSMC, but was not responsible for the effects of ET-1 and NA on actin filament remodelling or Hic-5 redistribution in VSMC. ET-1 stimulation caused an increase in Hic-5 localisation at FAs concurrent with an increase in the density of actin filaments, whereas NA stimulation caused a decrease in Hic-5 localisation at FAs in VSMC concurrent with actin filament redistribution at the cell cortex. Hic-5 was the FA protein that demonstrated the most dramatic changes in subcellular localisation in response to ET-1 and NA, when compared to paxillin (Hic-5 homologue) or vinculin (classical FA marker). NA-mediated changes in Hic-5 localisation and actin filament distribution were more pronounced compared to ET-1-mediated changes. Further investigation into the NA-induced changes suggested that actin filament disassembly preceded Hic-5 relocalisation from FAs to the cytosol. These results show that vasoactive peptides cause Hic-5 relocalisation and actin filament rearrangement in VSMCs in an agonist-dependent manner. Given that VSMC FA remodelling and actin cytoskeleton reorganisation occur during contraction and arterial remodelling, our data identify Hic-5 as a key regulator of these processes in response to NA and ET-1. Furthermore, these data have implications in agonist- specific VSM function such as migration and contraction.

Résumé :

The static and dynamic stiffnesses of contracted trachea smooth muscles are determined before, during and after length oscillations in isometric contraction. An appropriate Neural Network model is developed to normalize the data. The results indicate that the dynamic stiffness has the tendency of decreasing as the frequency and/or amplitude of external excitation increases. However, the static stiffness decreases with an increase in the frequency and amplitude of excitation until it reaches a critical value of frequency where no variation in stiffness is observed. It is postulated that the tissue elasticity and inertia are the main contributors to the dynamic stiffness while the myosin-actin cross bridge cycling is the main contributor to the static stiffness.

Résumé :

Superimposition of length fluctuations on contracted ASM have shown to reduce active force and stiffness. This effect is usually attributed to disruption of the actomyosin crossbridge cycle; however no direct experimental data is available to support this hypothesis. This in vitro study investigated the effect of the mechanical strains on 1) the ASM reactivity and 2) on the actin-myosin crossbridges. Experiments were carried out on maximally contracted bovine ASM subjected to length strains at various frequency in the range from 10 to 100Hz, superimposed on normal tidal stretches (frequency 0.33Hz, amplitude 4%). An organ bath system was used to apply strains and measure the force; immunofluorescence technique was performed to assess the crossbridges. The results show that superimposed length strains increase breathing relaxation effect with an optimal effect obtained at 50Hz. The cholinergic stimulation promotes actin-myosin connection, and length stretches promote the detachment of those crossbridges.

Résumé :

Fibroblast cells play a key role in producing and maintaining connective tissue throughout the body. The ability of these cells to differentiate into a more active myofibroblastic phenotype is important during development and wound healing, but prolonged myofibroblast activation can lead to overproduction of extracellular matrix proteins and stiffening of the surrounding tissue. This stiffening can cause heightened differentiation of neighboring fibroblast through force transduction pathways and can lead to detrimental fibrotic pathologies in many organ systems. Atherosclerosis, interstitial lung disease, cirrhosis and heart valve disease are fibrotic diseases that cause significant cost and mortality in our society. Understanding the processes by which cells sense and respond to substrate stiffness is crucial to the treatment of connective tissue diseases. One primary indicator of the myofibroblastic phenotype is the production of α smooth muscle actin (αSMA) bundles called stress fibers which help transmit stress inside the cell and increases the contractility of the cells and their surrounding tissue [1].
