The 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 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 کاملProperties of the fragmented sarcoplasmic reticulum from fast twitch and slow twitch muscles.
Skeletal muscle of guinea pigs is composed of at least three types of fibers which are distinguishable by their kinetic and histochemical properties. Fast twitch muscles may be histochemically red or white; fragmented sarcoplasmic reticulum (FSR) prepared from both types of fast twitch muscles has identical calcium-accumulating capacity (maximal calcium uptake) and calcium-concentrating ability...
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...
متن کاملAction potentials in fast- and slow-twitch mammalian muscles during reinnervation and development
Action potentials (APs) were recorded from the extrajunctional membrane of surface fibers of the fast-twitch extensor digitorum longus (extensor) and the slow-twitch soleus muscles of adult rats. APs of the extensor muscle had a significantly faster rate of rise and fall, as well as a shorter duration, than those of the soleus. In addition, the overshoot of APs and the resting membrane potentia...
