The ability of mother to provide nutrients and oxygen for her baby is a critical factor for fetal health and its survival. Failure in supplying the adequate amount of nutrients to meet fetal demand can lead to fetal malnutrition. The fetus responds and adapts to undernutrition but by doing so it permanently alters the structure and function of the body.(More)
We previously reported that maternal protein restriction in rodents influenced the rate of growth in early life and ultimately affected longevity. Low birth weight caused by maternal protein restriction followed by catch-up growth (recuperated animals) was associated with shortened lifespan whereas protein restriction and slow growth during lactation(More)
BACKGROUND It is well established that low birth weight and accelerated postnatal growth increase the risk of liver dysfunction in later life. However, molecular mechanisms underlying such developmental programming are not well characterized, and potential intervention strategies are poorly defined. OBJECTIVES We tested the hypotheses that poor maternal(More)
We determined the effects of maternal diet-induced obesity on offspring adipose tissue insulin signalling and miRNA expression in the aetiology of insulin resistance in later life. Although body composition and glucose tolerance of 8-week-old male offspring of obese dams were not dysregulated, serum insulin was significantly (p<0.05) elevated. Key insulin(More)
BACKGROUND It is now widely accepted that the early-life nutritional environment is important in determining susceptibility to metabolic diseases. In particular, intra-uterine growth restriction followed by accelerated postnatal growth is associated with an increased risk of obesity, type-2 diabetes and other features of the metabolic syndrome. The(More)
This study investigates the effects of diet-induced changes in maternal body condition on glucose tolerance in sheep. Welsh Mountain ewes were established, by dietary manipulation, at a body condition score of 2 (lower body condition [LBCS], n = 17) or >3 (higher body condition [HBCS], n = 19) prior to and during pregnancy. Birth weight and postnatal growth(More)
Individuals with a low birthweight have an increased risk of developing type 2 diabetes mellitus in adulthood. This is associated with peripheral insulin resistance. Here, we aimed to determine whether changes in insulin signalling proteins in white adipose tissue (WAT) can be detected prior to the onset of impaired glucose tolerance, determine whether(More)
Low birth weight is associated with increased cardiovascular disease (CVD) in humans. Detrimental effects of low birth weight are amplified by rapid catch-up growth. Conversely, slow growth during lactation reduces CVD risk. Gestational protein restriction causes low birth weight, vascular dysfunction, and accelerated aging in rats. Atherosclerotic aortic(More)
AIMS/HYPOTHESIS Individuals with low birthweight are at increased risk of type 2 diabetes mellitus. However, the underlying molecular mechanisms are unknown. Previously we have shown that low birthweight is associated with changes in muscle insulin signalling proteins. Here we determined whether low birthweight is associated with changes in insulin(More)
BACKGROUND & AIMS Obesity induced, non-alcoholic fatty liver disease (NAFLD), is now the major cause in affluent countries, of the spectrum of steatosis-to-cirrhosis. Obesity and NAFLD rates in reproductive age women, and adolescents, are rising worldwide. Our hypothesis was that maternal obesity and lactation transmit to the offspring a pre-disposition to(More)
