Abstract
Besides the well-recognized influence of maternal health on fetal in utero development, recent epidemiological studies appoint paternal preconception metabolic health as a significant factor in shaping fetal metabolic programming and subsequently offspring metabolic health; however, mechanisms behind these adaptations remain confined to animal models. To elucidate the effects of paternal obesity (P-OB) on infant metabolism in humans, we examined mesenchymal stem cells (MSCs), which give rise to infant tissue, remain involved in mature tissue maintenance, and resemble the phenotype of the offspring donor. Here, we assessed mitochondrial functional capacity, content, and insulin action in MSC from infants of fathers with overweight [body mass index (BMI: 25-30 kg/m2); paternal overweight (P-OW)] or obesity (BMI ≥ 30 kg/m2; P-OB) while controlling for maternal intrauterine environment. Compared with P-OW, infant MSCs in the P-OB group had lower intact cell respiration, OXPHOS, and electron transport system capacity, independent of any changes in mitochondrial content. Furthermore, glucose handling, insulin action, lipid content, and oxidation were similar between groups. Importantly, infants in the P-OB group had a greater weight-to-length ratio, which could be in part due to changes in MSC metabolic functioning, which precedes and, therefore, influences infant growth trajectories. These data suggest that P-OB negatively influences infant MSC mitochondria. ClinicalTrials.gov Identifier: NCT03838146.NEW & NOTEWORTHY Paternal obesity decreases infant mesenchymal stem cell (MSC) basal and maximal respiration. Lower OXPHOS and electron transport system capacity could be explained by lower complex I and IV respiratory capacity but not changes in OXPHOS expression in infant MSC from fathers with obesity. Paternal obesity and altered MSC mitochondrial functional capacity are associated with a greater infant weight-to-length ratio at birth.
期刊介绍:
The American Journal of Physiology-Endocrinology and Metabolism publishes original, mechanistic studies on the physiology of endocrine and metabolic systems. Physiological, cellular, and molecular studies in whole animals or humans will be considered. Specific themes include, but are not limited to, mechanisms of hormone and growth factor action; hormonal and nutritional regulation of metabolism, inflammation, microbiome and energy balance; integrative organ cross talk; paracrine and autocrine control of endocrine cells; function and activation of hormone receptors; endocrine or metabolic control of channels, transporters, and membrane function; temporal analysis of hormone secretion and metabolism; and mathematical/kinetic modeling of metabolism. Novel molecular, immunological, or biophysical studies of hormone action are also welcome.
