Developmental Programming in Response to Intrauterine Growth Restriction Impairs Myoblast Function and Skeletal Muscle Metabolism
Fetal adaptations to placental insufficiency alter postnatal metabolic homeostasis in skeletal muscle by reducing glucose oxidation rates, impairing insulin action, and lowering the proportion of oxidative fibers. In animal models of intrauterine growth restriction (IUGR), skeletal muscle fibers have less myonuclei at birth. This means that myoblasts, the sole source for myonuclei accumulation ...
متن کاملDevelopmental programming of skeletal muscle phenotype/metabolism.
Skeletal muscle is a highly dynamic and malleable tissue that is able to adapt to different stimuli placed upon it, both during gestation and after birth, ultimately resulting in anatomical changes to muscle fibre composition. Variation in nutrient supply throughout gestation is common, whether in livestock or in the human. The specific effects of maternal nutrition on foetal development are at...
متن کاملRole of resistance training with the approach of blood flow restriction in skeletal muscle cell growth
Background: The aim of this study was to investigate the response of ERK1/2 protein and muscular morphological adaptations to a period of resistance training with local blood flow restriction. Materials and methods: Twenty healthy male Wistar rats without clinically evident disease (5 weeks old, 120±7 g weight) were divided into four equal groups: control, control with limited blood flow...
متن کاملSkeletal Muscle Function and Metabolism
Skeletal muscle consists of bundles of long spindle shaped cells called muscle fibers that attach to bone by tendinous insertions. The blood vessels and nerves that nourish and control muscle function run in thin sheets of connective tissue that surround bundles of muscle fibers. Each nerve branch communicates with one muscle fiber at the motor end. The nerve and all the muscle fibers that it s...
متن کاملPrenatal programming of insulin secretion in intrauterine growth restriction.
Intrauterine growth restriction (IUGR) impairs insulin secretion in humans and in animal models of IUGR. Several underlying mechanisms have been implicated, including decreased expression of molecular regulators of β-cell mass and function, in some cases shown to be due to epigenetic changes initiated by an adverse fetal environment. Alterations in cell cycle progression contribute to loss of β...
