Effect of in utero undernutrition on skeletal muscle gene expression

ABSTRACT: In utero undernutrition is associated with obesity and insulin resistance, although its effect on skeletal muscle remains poorly defined. We report that, in mice, adult offspring from undernourished dams have decreased energy expenditure, decreased skeletal muscle mitochondrial content, and altered energetics in isolated mitochondria and permeabilized muscle fibers. Strikingly, when these mice are put on a 40% calorie restricted diet they lose half as much weight as calorie restricted controls. Our results reveal for the first time that in utero undernutrition alters metabolic physiology having a profound effect on skeletal muscle energetics and response to calorie restriction in adulthood.

Our results reveal for the first time that in utero undernutrition alters metabolic physiology having a profound effect on skeletal muscle energetics and response to calorie restriction in adulthood. We have used a mouse model of low birth weight generated through 50% food restriction of mouse dams during the third week of gestation. We have studied in utero food restricted offspring and control offspring that were not food restricted in utero in both the ad libitum and calorie restricted states. Gene expression profiling was performed on tibialis anterior muscle from 8 mice per group, pooled in pairs.

Effects of maternal nutrient restriction during pregnancy on the adult offspring longissimus dorsi transcriptome in cattle

Project description:Maternal undernutrition during pregnancy followed by ad libitum access to nutrients during postnatal life induces postnatal metabolic disruptions in multiple species. As skeletal muscle is a major metabolic organ, RNAseq was performed on the longissimus dorsi muscles of slaughter-weight adult females that had been exposed to nutrient-restriction in utero.

Intrauterine hyponutrition reduces fetal testosterone production and postnatal sperm count in the C57BL/6N

Project description:There has been growing interest in the relationship between maternal undernutrition and reproductive disorders in male offspring. In the present study, we determined the effects of maternal calorie restriction throughout the critical period for in utero development of the male reproductive system, termed the “masculinization programming window” on the reproductive system of mice. The intratesticular testosterone concentration of the fetuses of calorie-restricted (R) dams was lower than in control fetuses at 17.5 days post coitum. In addition, there was global down-regulation of genes encoding steroidogenic enzymes and a low sperm count in the offspring of R dams (R-offspring) at 6 weeks of age. Microarray analysis of the testes of the offspring identified dysregulation of several genes that might explain the derangement in spermatogenesis in the R-offspring. Thus, the present study provides insights into the impact of maternal undernutrition on the male reproductive system in mice. The deleterious effects probably originate in lower androgen exposure during the “masculinization programming window.”

Primary muscle cells from in-utero undernourished mice

Project description:ICR mice, age 6-8 weeks.(Harlan, Indianapolis, IN, USA). Housed individually with controlled temperature, humidity, and light-dark cycle (0600h – 1800h). Pregnant mice were housed individually with ad libitum access to standard rodent chow (T.2018, Harlan Teklad, Indianapolis, IN, USA). On day 12.5 of pregnancy, dams were randomly assigned to either a control or undernutrition group. In the undernutrition group, food was restricted to 50% that of gestational day -matched controls for the remainder of pregnancy. After delivery, mothers were given ad libitum access to chow and 24 hours after birth, litters were equalized to eight. We studied mice from 2 groups: in utero undernourished offpring (U) and control offspring (C). Primary muscle cells were isolated from the quadriceps of U and C at 3 weeks old. Isolated primary muscle cells were grown on Matrigel coated flasks in low glucose (5.5 mmol/L) Dulbecco’s Modified Eagle’s Medium (DMEM) supplemented with 20% FBS, 1X antibiotic-antimycotic, 2.5μg/ml gentamycin and 2.5ng/ml basic fibroblast growth factor. When cells reached approximately 90% confluency, they were differentiated in low glucose DMEM supplemented with 2% FBS, 1X antibiotic-antimycotic, and 2.5μg/ml gentamycin. Other cells were cultured overnight in substrate limited medium (glucose and glutamine free DMEM supplemented with 0.5mM glucose, 1mM glutamine, 0.5mM carnitine and 1% (v/v) FBS; pH 7.4).

Cross-feeding between intestinal pathobionts promotes their overgrowth during undernutrition

Project description:Child undernutrition is a global health issue associated with a high burden of infectious disease. Undernourished children display an overabundance of intestinal pathogens and pathobionts, and these bacteria induce enteric dysfunction in undernourished mice; however, the cause of their overgrowth remains poorly defined. Here, we show that disease-inducing human isolates of Enterobacteriaceae and Bacteroidales spp. are capable of multi-species symbiotic cross-feeding, resulting in synergistic growth of a mixed community in vitro. Growth synergy occurs uniquely under malnourished conditions limited in protein and iron: in this context, Bacteroidales spp. liberate diet- and mucin-derived sugars and Enterobacteriaceae spp. enhance the bioavailability of iron. Analysis of human microbiota datasets reveals that Bacteroidaceae and Enterobacteriaceae are strongly correlated in undernourished children, but not in adequately nourished children, consistent with a diet-dependent growth synergy in the human gut. Together these data suggest that dietary cross-feeding fuels the overgrowth of pathobionts in undernutrition.

Transcription profiling of mouse heart, brain, and skeletal muscle to determine the rffect of age, calorie restriction and resveratrol on gene expression

Project description:Resveratrol in high doses has been shown to extend lifespan in some studies in invertebrates and to prevent early mortality in mice fed a high-fat diet. We fed mice from middle age (14-months) to old age (30-months) either a control diet, a low dose of resveratrol (4.9 mg kg-1 day-1), or a calorie restricted (CR) diet and examined genome-wide transcriptional profiles. We report a striking transcriptional overlap of CR and resveratrol in heart, skeletal muscle and brain. Both dietary interventions inhibit gene expression profiles associated with cardiac and skeletal muscle aging. Gene expression profiling suggests that both CR and resveratrol may retard some aspects of aging through alterations in chromatin structure and transcription. Resveratrol, at doses that can be readily achieved in humans, fulfills the definition of a dietary compound that mimics some aspects of CR. Experiment Overall Design: Heart, neocortex tissue, and gastrocnemius muscle was collected from young and old mice at 5 and 30 months of age, respectively; mice were subjected to either a calorie restricted diet or a control diet supplemented with resveratrol

Characterization of the skeletal muscle proteome in under-nourished old rats

Project description:Therefore, undernutrition is common in the elderly where its prevalence varies from 4 to 10% at home, from 15 to 30% in care homes and reaches 30 to 70% in hospitals de-pending on the diagnostic criteria used [10]. Most of all, aging impairs the ability to adapt to undernutrition leading to severe loss of body weight and muscle [11-14]. In particular, old rats exhibit defective adaptation to long-term 50% dietary restriction initiated at an advanced age, resulting in dramatic body weight loss and deregulation of protein metabolism in terms of nitrogen balance and protein content, especially at skeletal muscle level [12]. Therefore, in elderly patients, undernutrition exacerbates the state of frailty and dependence, greatly increasing the risk of morbidity and mortality [15]. This is even more critical that the world aging population is growing up. Accord-ing to United Nations statistics on the demographic trend in aging population, the proportion of persons aged 65 or over in the world is projected to reach nearly 16% in 2050, compared to 9% in 2019 [16]. Specific studies are needed to better understand the undernutrition-induced skeletal muscle alterations in order to identify new therapeu-tic targets and prevent sarcopenia in the old population

Muscle fiber transdifferentiation in an experimental model of respiratory chain myopathy

Project description:Skeletal muscle fiber composition and muscle energetics are not static and change in muscle disease. This study was performed to determine if a mitochondrial myopathy is associated with adjustments in skelatal fiber type composition. These effects of drug induced mitochondrial dysfunction on skeletal muscle fiber type composition were analyzed in an animal model.
