Abstract
Skeletal muscle plays a crucial role in maintaining metabolism, energy homeostasis, movement, as well as endocrine function. The gestation period is a critical stage for myogenesis and development of the skeletal muscle. Adverse environmental exposures during pregnancy may impose various effects on the skeletal muscle health of the offspring. Maternal obesity during pregnancy can mediate lipid deposition in the skeletal muscle of the offspring by affecting fetal skeletal muscle metabolism and inflammation-related pathways. Poor dietary habits during pregnancy, such as high sugar and high fat intake, can affect autophagy of skeletal muscle mitochondria and reduce the quality of the offspring skeletal muscle. Nutritional deficiencies during pregnancy can affect the development of the offspring skeletal muscle through epigenetic modifications. Gestational diabetes may affect the function of the offspring skeletal muscle by upregulating the levels of miR-15a and miR-15b in the offspring. Exposure to environmental endocrine disruptors during pregnancy may impair skeletal muscle function by interfering with insulin receptor-related signaling pathways. This article reviews the research progress on effects and possible mechanisms of adverse maternal exposures during pregnancy on the offspring skeletal muscle function based on clinical and animal studies, aiming to provide scientific evidence for the prevention and treatment strategies of birth defects in the skeletal muscle.
