Abstract:
α-Syntrophin is a scaffolding adapter protein expressed primarily on the sarcolemma of skeletal muscle. The COOH-terminal half of α-syntrophin binds to dystrophin and related proteins, leaving the PSD-95, discs-large, ZO-1 (PDZ) domain free to recruit other proteins to the dystrophin complex. We investigated the function of the PDZ domain of α-syntrophin in vivo by generating transgenic mouse lines expressing full-length α-syntrophin or a mutated α-syntrophin lacking the PDZ domain (ΔPDZ). The ΔPDZ α-syntrophin displaced endogenous α- and β1-syntrophin from the sarcolemma and resulted in sarco

Abstract:
We used immunofluorescence techniques and confocal imaging to study the organization of the membrane skeleton of skeletal muscle fibers of mdx mice, which lack dystrophin. β-Spectrin is normally found at the sarcolemma in costameres, a rectilinear array of longitudinal strands and elements overlying Z and M lines. However, in the skeletal muscle of mdx mice, β-spectrin tends to be absent from the sarcolemma over M lines and the longitudinal strands may be disrupted or missing. Other proteins of the membrane and associated cytoskeleton, including syntrophin, β-dystroglycan, vinculin, and Na,K-A

Abstract:
The absence of dystrophin complex leads to disorganization of the force-transmitting costameric cytoskeleton and disruption of sarcolemmal membrane integrity in skeletal muscle. However, it has not been determined whether the dystrophin complex can form a mechanically strong bond with any costameric protein. We performed confocal immunofluorescence analysis of isolated sarcolemma that were mechanically peeled from skeletal fibers of mouse hindlimb muscle. A population of γ-actin filaments was stably associated with sarcolemma isolated from normal muscle and displayed a costameric pattern that

Abstract:
The expression of the Na+/Ca2+ exchanger was studied in differentiating muscle fibers in rats. NCX1 and NCX3 isoform (Na+/Ca2+ exchanger isoform) expression was found to be developmentally regulated. NCX1 mRNA and protein levels peaked shortly after birth. Conversely, NCX3 isoform expression was very low in muscles of newborn rats but increased dramatically during the first 2 wk of postnatal life. Immunocytochemical analysis showed that NCX1 was uniformly distributed along the sarcolemmal membrane of undifferentiated rat muscle fibers but formed clusters in T-tubular membranes and sarcolemma o

Abstract:
Duchenne's muscular dystrophy (DMD) is caused by the absence or drastic decrease of the structural protein, dystrophin, and is characterized by sarcolemmal lesions in skeletal muscle due to the stress of contraction. Dystrophin has been localized to the sarcolemma, but its organization there is not known. We report immunofluorescence studies which show that dystrophin is concentrated, along with the major muscle isoform of beta-spectrin, in three distinct domains at the sarcolemma: in elements overlying both I bands and M lines, and in occasional strands running along the longitudinal axis of

Abstract:
The sarcolemma of fast-twitch muscle is organized into “costameres,” structures that are oriented transversely, over the Z and M lines of nearby myofibrils, and longitudinally, to form a rectilinear lattice. Here we examine the role of desmin, the major intermediate filament protein of muscle in organizing costameres. In control mouse muscle, desmin is enriched at the sarcolemmal domains that lie over nearby Z lines and that also contain β-spectrin. In tibialis anterior muscle from mice lacking desmin due to homologous recombination, most costameres are lost. In myofibers from desmin −/− quadr

An improved immunogold labeling procedure was used to examine the subcellular distribution of glucose transporters in Lowricryl HM20-embedded skeletal muscle from transgenic mice overexpressing either Glut1 or Glut4. In basal muscle, Glut4 was highly enriched in membranes of the transverse tubules and the terminal cisternae of the triadic junctions. Less than 10% of total muscle Glut4 was present in the vicinity of the sarcolemmal membrane. Insulin treatment increased the number of gold particles associated with the transverse tubules and the sarcolemma by three-fold. However, insulin also inc

mAbs specific for protein components of the surface membrane of rabbit skeletal muscle have been used as markers in the isolation and characterization of skeletal muscle sarcolemma membranes. Highly purified sarcolemma membranes from rabbit skeletal muscle were isolated from a crude surface membrane preparation by wheat germ agglutination. Immunoblot analysis of subcellular fractions from skeletal muscle revealed that dystrophin and its associated glycoproteins of 156 and 50 kD are greatly enriched in purified sarcolemma vesicles.

Abstract:
ABSTRACT Sarcospan is an integral membrane component of the dystrophin-glycoprotein complex (DGC) found at the sarcolemma of striated and smooth muscle. The DGC plays important roles in muscle function and viability as evidenced by defects in components of the DGC, which cause muscular dystrophy. Sarcospan is unique among the components of the complex in that it contains four transmembrane domains with intracellular N- and C-terminal domains and is a member of the tetraspan superfamily of proteins. Sarcospan is tightly linked to the sarcoglycans, and together these proteins form a subcomplex w

Abstract:
Phospholipid incorporation of 32P by primary myotube cultures and the tissue activity of sarcolemmal Na+/K+-transporting ATPase were studied to determine whether the absence of dystrophin from dystrophic (mdx) muscle would affect membrane lipid synthesis and membrane function. The incorporation of 32P by phospholipid as a ratio with total protein was greater in cultured dystrophic cells compared with control cells. The mdx cells also incorporated more 32P than control cells into phosphatidylethanolamine, which is thought to increase prior to myoblast fusion, and less into phosphatidylserine, p

Abstract:
Three genes coding sarcoplasmic reticulum Ca$\sp{2+}$-ATPases (SERCA) and at least four genes coding sarcolemmal Ca$\sp{2+}$-ATPase (PMCA) have been isolated and characterized. The objective of this work was to study the mRNA expression for Ca$\sp{2+}$-ATPase isoforms during in vitro differentiation of skeletal muscle cell lines. To analyze the mRNA expression pattern of the SERCA and PMCA isoforms, three skeletal muscle cell lines (L6, C2C12, Sol8) were used as models. The mRNAs of these Ca$\sp{2+}$-ATPase gene were detected by a semi-quantitatively RT-PCR technique. It is generally regarded

Abstract:
The motor unit—the final common pathway for all voluntary muscle activity—is composed of an anterior horn cell, its peripheral axon, the axon terminal branches, the associated neuromuscular junctions, and the muscle fibres innervated. The muscle cells are multinucleate units with unique structures adapted for response to metabolic, nervous, and autocrine signals. Meanwhile, there are also different types of motor units: type 1—rich in mitochondria and specialized for oxidative metabolism of fat; type 2—larger fibres with abundant glycogen that generate energy by glycosis and are critical for short-lived muscle contraction. Knowledge of the underlying molecular cell biology, neurophysiology, and biochemical energetics of muscle provides a useful basis for understanding the symptoms, signs, and pathogenesis of clinical disorders affecting the muscles. Mutations in sarcolemmal proteins, such as dystrophin, cause diseases with widespread effects on skeletal muscle function, the heart, and survival.
