  1. 1. The muscle cytoskeleton of mice and men : Structural remodelling in desmin myopathies

    Författare :Lena Carlsson; Lars-Eric Thornell; Anders Arnér; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; desmin; nestin; synemin; paranemin; plectin; αB-crystallin; skeletal muscle; heart muscle; myotendinous junction; motor endplate; costamere; anatomi; Human Anatomy;

    Sammanfattning : The muscle fibre cytoskeleton of skeletal and heart muscle cells is composed mainly of intermediate filaments (IFs), that surround the myofibrils and connect the peripheral myofibrils with the sarcolemma and the nuclear membrane. Desmin is the first muscle specific IF protein to be produced in developing muscles and is the main IF protein in mature muscles. LÄS MER

  3. 2. Structure and function of the cytoskeleton in cardiac and skeletal muscle

    Författare :Johanna Balogh; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ATP-receptor; Cardiovascular system; Kardiovaskulära systemet; cardiomyopathy; transgenic mice; skeletal muscle; heart; muscle contraction; cytoskeleton; desmin;

    Sammanfattning : We have examined the functional and structural roles of the cytoskeletal protein desmin in cardiac and skeletal muscles using a genetically modified mouse (Des-/-) with the desmin gene ablated. Desmin forms filaments at the Z-disks in the striated muscle sarcomere, have connections to the sarcolemma and most likely align sarcomeres and whole cells. LÄS MER

  4. 3. Genetic studies of zebrafish muscles : clues to protection in muscle disease

    Författare :Nils Dennhag; Fatima Pedrosa Domellöf; Jonas von Hofsten; Tatjana Haitina; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; zebrafish; muscle; extraocular muscles; intermediate filaments; bioinformatics; genetics; CRISPR Cas9; oftalmiatrik; ophthalmology; cellforskning; cell research;

    Sammanfattning : Muscular dystrophies (MDs) are caused by dysregulation of over 40 proteins but commonly share features of muscle weakness, myofiber death and regeneration, loss of ambulation and premature death. A MD involves a broken link anywhere in the connection from extracellular matrix through the sarcolemma to the sarcomere. LÄS MER

  5. 4. A Muscle Perspective on the Pathophysiology of Amyotrophic Lateral Sclerosis : Differences between extraocular and limb muscles

    Författare :Vahid M. Harandi; Jingxia Liu; Fatima Pedrosa Domellöf; Per Stål; Fawzi Kadi; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuromuscular junctions; Extraocular muscles; Skeletal muscle; Neurotrophic factor; Wnt; Motor neuron disease; Amyotrophic lateral sclerosis; SOD1G93A mice; molekylärbiologi; Molecular Biology;

    Sammanfattning : Background: Amyotrophic lateral sclerosis (ALS) is a late-onset progressive neurodegenerative disorder. ALS has been traditionally believed to be primarily a motor neuron disease. LÄS MER

  7. 5. Re-evaluation of exercise-induced muscle soreness : an immunohistochemical and ultrastructural study

    Författare :Ji-Guo Yu; Bengt Saltin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anatomy; Anatomi; Anatomy; Anatomi;

    Sammanfattning : Delayed onset muscle soreness (DOMS) is a familiar experience for the elite and novice athletes. Symptoms can range from muscle tenderness to severe deliberating pain. It is generally believed that eccentric contractions produce higher tension on muscle fibres and connective tissues than concentric and isometric contractions. LÄS MER
