The Fine Structure of Fast and Slow Crustacean Muscles
Known phasic and tonic muscle fibers of the crab Cancer magister were studied by electron microscopy. Phasic fibers have sarcomeres about 4.5 micro long, small polygonal myofibrils, and a well-developed sarcoplasmic reticulum. The thick myofilaments, disposed in hexagonal array, are each surrounded by six thin filaments. The tonic fibers have a sarcomere length of about 12 micro, larger myofibr...
متن کاملThe aerobic maternal exercise increases PDK4 gene expression in slow and fast twitch muscles of rat male offspring.
Recent studies indicate that environment can modify skeletal muscle gene expression and transcriptional factors in offspring genes. Therefore, exercising can lead to changes in the gene expression of the future generations. One of the important metabolic factors is PDK4, which is known as the main factor in Pyruvate Dehydrogenase Complex (PDC). This study examined the effects of maternal exerci...
متن کاملthe effect of resistance exercise on myod expression in slow and fast muscles of wistar rats
abstractbackground and objective: satellite cells are muscle stem cells that enter cycle cells due to myotrauma. among activation and proliferation indices of these cells is increase of myod gene expression. but these are contradiction in response of this gene to resistance exercise in fast and slow fibers. thus, the aim of this study was to evaluate the effect of a single bout of resistance ex...
متن کاملEffect of progressive resistance exercise on β1 integrin and vinculin protein levels in slow-and fast-twitch skeletal muscles of male rats
Introduction: Skeletal muscle is a flexible and ever changing tissue and the role of costameric proteins in its response to different stimuli is not well defined. The aim of this study was to investigate the effect of progressive resistance exercise on β1 integrin and vinculin proteins in fast and slow twitch skeletal muscles of male rats. Methods: Twelve male Wistar rats (weight: 298±5.2 gr...
متن کاملThe Effect of Intensive Endurance Activity on Myocyte Enhancer Factor 2C Gene Expression of Slow and Fast Twitch Muscles in Male Wistar Rats: An Experimental Study
Background and Objectives: Myocyte enhancer factor 2c activates the genes of the slow-twitch muscle, the muscle which plays role in endurance activity. Therefore, the aim of this study was to evaluate the effect of a program of intensive endurance activity on MEF2c gene expression in fast and slow twitch skeletal muscles in wistar rats. Materials and Methods: In this experimental study, 14 mal...
