Expression of MyoD, myogenin, myostatin and Hsp70 transcripts in chicken embryos submitted to mild cold or heat
(Elsevier B.V., 2003-05-01)
The expression of the MyoD, myogenin, myostatin and Hsp70 genes was estimated in chicken embryos submitted to mild cold (36 +/- 0.5degreesC) or heat (44 +/- 0.5degreesC) for 1 h. 2. Marked decreases in MyoD, myogenin and ...
Morphometry and expression of MyoD and Myogenin in white and red skeletal muscles of juvenile fish Colossoma macropomum (Cuvier 1818)
(2013-07-10)
Colossoma macropomum, also known as tambaqui, is an economically important fish species, and interesting new studies have been published with the aim of improving the growth of this fish. In this work, we describe the ...
The Cavβ1a subunit regulates gene expression and suppresses myogenin in muscle progenitor cells
(Rockefeller Univ Press, 2014-06)
Voltage-gated calcium channel (Cav) subunits are auxiliary subunits to Cavs. Recent reports show Cavsubunits may enter the nucleus and suggest a role in transcriptional regulation, but the physiological rele-vance of ...
Maternal protein restriction induce skeletal muscle changes without altering the MRFs MyoD and myogenin expression in offspring
(Springer, 2012-10-01)
Stimuli during pregnancy, such as protein restriction, can affect morphophysiological parameters in the offspring with consequences in adulthood. The phenomenon known as fetal programming can cause short- and long-term ...
Quantitative expression of myogenic regulatory factors MyoD and myogenin in pacu (Piaractus mesopotamicus) skeletal muscle during growth
(Pergamon-Elsevier B.V. Ltd, 2010-12-01)
Skeletal muscle growth is regulated by differential expression of myogenic regulatory factors (MRFs). We evaluated hyperplasia, hypertrophy and quantitative expression of MRFs MyoD and myogenin in 45, 90, 180, and 400 days ...
MyoD, myogenin and proliferating cell nuclear antigen expression in growing Nile tilapia (Oreochromis niloticus L.)
(Wiley-Blackwell, 2008-11-04)
In the present study, immunohistochemical and morphometric analysis was used to characterize variations in muscle growth performance during muscle fibre recruitment and hypertrophy. As in fisheries, fish were classified ...
Training improves the oxidative phenotype of muscle during the transition from cardiac hypertrophy to heart failure without altering MyoD and myogenin
(2016-08-01)
New Findings: What is the central question of this study? We investigated the effects of physical training on phenotypic (fibre-type content) and myogenic features (MyoD and myogenin expression) in skeletal muscle during ...
Myogenin, MyoD and IGF-I regulate muscle mass but not fiber-type conversion during resistance training in rats
(2013-01-01)
The purpose of this study was to test the hypothesis that skeletal muscle adaptations induced by long-term resistance training (RT) are associated with increased myogenic regulatory factors (MRF) and insulin-like growth ...
Resistance training with excessive training load and insufficient recovery alters skeletal muscle mass-related protein expression
(Lippincott Williams & Wilkins, 2014-08-01)
The aim of this study was to investigate the effects of a resistance training program with excessive training load and insufficient recovery time between bouts on muscle hypertrophy-and atrophy-related protein expression. ...
Does alveolar soft-part sarcoma exhibit skeletal muscle differentiation? An immunocytochemical and biochemical study of myogenic regulatory protein expression
(Williams & Wilkins, 1996-05-01)
There has been persistent controversy regarding the nature of cell differentiation in alveolar soft-part sarcoma (ASPS) since its first description in 1952. Some studies suggest that ASPS might represent an unusual variant ...
