Properties 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 کاملPostnatal changes in insulin binding in slow and fast-twitch rabbit skeletal muscles.
Changes of insulin binding characteristics (number of receptors, Kd) were studied in the semimembranosus proprius (SMP) and psoas major (PM) muscle from birth to adult stage. The Kd was about 0.15 10(-9) M in both muscles and did not change with age. The numbers of receptors were similar in both muscles at birth and changed differently thereafter to reach 1.3 fmoles per mg of muscle in the PM a...
متن کاملHomer 2 antagonizes protein degradation in slow-twitch skeletal muscles.
Homer represents a new and diversified family of proteins made up of several isoforms. The presence of Homer isoforms, referable to 1b/c and 2a/b, was investigated in fast- and slow-twitch skeletal muscles from both rat and mouse. Homer 1b/c was identical irrespective of the muscle, and Homer 2a/b was instead characteristic of the slow-twitch phenotype. Transition in Homer isoform composition w...
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 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...
