PURPOSE This study was aimed to investigate the effects of a maternal low-protein diet on transcriptional regulation of the myostatin (MSTN) gene in skeletal muscle of weaning piglets. METHODS Sows were fed either a standard-protein (SP, 15 and 18 % crude protein) or a low-protein (LP, 50 % protein level of SP) diet throughout pregnancy and lactation.(More)
Maternal malnutrition may disrupt ovarian functions in adult offspring. Steroidogenesis and folliculogenesis in the offspring ovary appear to be the major targets of nutritional programming. Nevertheless, the mechanism by which maternal low-protein diet affects the offspring steroidogenesis and folliculogenesis, and the possible pathway linking these two(More)
Betaine has been widely used in animal and human nutrition to promote muscle growth and performance, yet it remains unknown whether maternal betaine supplementation during gestation affects the metabolic characteristics of neonatal skeletal muscles. In the present study, feeding sows with betaine-supplemented diets throughout gestation significantly(More)
Maternal malnutrition during pregnancy may give rise to female offspring with disrupted ovary functions in adult age. Neonatal ovary development predisposes adult ovary function, yet the effect of maternal nutrition on the neonatal ovary has not been described. Therefore, here we show the impact of maternal protein restriction on the expression of(More)
PURPOSE The study aimed to determine the effects of maternal low-protein (LP) diet on subcutaneous fat deposition of weaning piglets and the potential mechanism. METHODS Sows were fed either a standard protein (SP, 15 and 18% crude protein) or a LP diet (50% protein levels of SP) throughout pregnancy and lactation. Subcutaneous fat and blood were sampled(More)
PURPOSE The adequate supply of methyl donors is critical for the normal development of brain. The purpose of the present study was to investigate the effects of maternal betaine supplementation on hippocampal gene expression in neonatal piglets and to explore the possible mechanisms. METHODS Gestational sows were fed control or betaine-supplemented (3(More)
In this study, gestational sows were fed control or betaine-supplemented diets (3 g/kg) throughout the pregnancy, and the newborn piglets were used to elucidate whether maternal dietary betaine affected offspring hepatic gluconeogenic genes through epigenetic mechanisms. Neonatal piglets born to betaine-supplemented sows had significantly higher serum and(More)
To elucidate the effects of maternal dietary betaine supplementation on hepatic expression of cholesterol metabolic genes in newborn piglets and the involved epigenetic mechanisms, we fed gestational sows with control or betaine-supplemented diets (3 g/kg) throughout pregnancy. Neonatal piglets born to betaine-supplemented sows had higher serum methionine(More)
Obesity is associated with hepatic mitochondrial dysfunction. The relationship between glucocorticoids (GCs) and obesity has also been demonstrated in several researches. Recent research showed that GCs can affect the mitochondrial function. However, the role of glucocorticoid receptor (GR) in obesity-induced mitochondrial dysfunction remains unclear.(More)
