Myosin heavy chain expression and atrophy in rat skeletal muscle during transition from cardiac hypertrophy to heart failure
(Blackwell Publishing, 2003-08-01)
The purpose of this investigation was to determine whether changes in myosin heavy chain (MHC) expression and atrophy in rat skeletal muscle are observed during transition from cardiac hypertrophy to chronic heart failure ...
High-Intensity Resistance Training with Insufficient Recovery Time Between Bouts Induce Atrophy and Alterations in Myosin Heavy Chain Content in Rat Skeletal Muscle
(Wiley-Blackwell, 2011-08-01)
The aim of this study was to test whether high-intensity resistance training with insufficient recovery time between bouts, could result in a decrease of muscle fiber cross-sectional area (CSA), alter fiber-type frequencies ...
Heart failure alters MyoD and MRF4 expressions in rat skeletal muscle
(2006-06-01)
Heart failure (HF) is characterized by a skeletal muscle myopathy with increased expression of fast myosin heavy chains (MHCs). The skeletal muscle-specific molecular regulatory mechanisms controlling MHC expression during ...
Heart failure-induced skeletal myopathy in spontaneously hypertensive rats
(2013-08-10)
Background: Although skeletal muscle atrophy and changes in myosin heavy chain (MyHC) isoforms have often been observed during heart failure, their pathophysiological mechanisms are not completely defined. In this study ...
Down-regulation of MyoD gene expression in rat diaphragm muscle with heart failure
(Wiley-Blackwell, 2008-06-01)
Diaphragm myopathy has been described in patients with heart failure (HF), with alterations in myosin heavy chains (MHC) expression. The pathways that regulate MHC expression during HF have not been described, and myogenic ...
Localization of myosin-Va in subpopulations of cells in rat endocrine organs
(2008-08-01)
Myosin-Va is a Ca 2+/calmodulin-regulated unconventional myosin involved in the transport of vesicles, membranous organelles, and macromolecular complexes composed of proteins and mRNA. The cellular localization of myosin-Va ...
T-cell molecular mimicry in Chagas disease: identification and partial structural analysis of multiple cross-reactive epitopes between Trypanosoma cruzi B13 and cardiac myosin heavy chain
(Elsevier B.V., 2005-03-01)
Chagas disease cardiornyopathy (CCC) is one of the few examples of post-infectious autoimmunity, where infectious episodes with an established pathogen, the protozoan parasite Trypanosoma cruzi, clearly triggers molecular ...
Muscle fiber type characterization and myosin heavy chain (MyHC) isoform expression in Mediterranean buffaloes
(Elsevier B.V., 2011-07-01)
This study aimed to evaluate myosin heavy chain (MyHC) isoform expression and muscle fiber types of Longissimus dorsi (LD) and Semitendinosus (ST) in Mediterranean buffaloes and possible fibers muscles modulation according ...
Chronic heart failure-induced skeletal muscle atrophy, necrosis, and changes in myogenic regulatiory factors
(Int Scientific Literature, Inc, 2010-12-01)
Background: Although intrinsic skeletal muscle abnormalities can influence exercise intolerance during heart failure (HF), the factors responsible for muscle changes have not been elucidated. In this study we evaluated the ...
