People with low birthweight have an increased risk of developing type 2 diabetes mellitus in adulthood. The mechanistic basis of this phenomenon is not known. Here we investigate the effect of early growth restriction on the expression of insulin-signalling proteins in skeletal muscle in a human cohort and a rat model. We recruited 20 young men with low(More)
Maternal obesity is increasingly prevalent and may affect the long-term health of the child. We investigated the effects of maternal diet-induced obesity in mice on offspring metabolic and cardiovascular function. Female C57BL/6J mice were fed either a standard chow (3% fat, 7% sugar) or a palatable obesogenic diet (16% fat, 33% sugar) for 6 weeks before(More)
Developmental programming of non-communicable diseases is now an established paradigm. With respect to hypertension and chronic kidney disease, adverse events experienced in utero can affect development of the fetal kidney and reduce final nephron number. Low birthweight and prematurity are the most consistent clinical surrogates for a low nephron number(More)
The measurement of insulin Non-insulin-dependent diabetes mellitus (NIDDM) is estimated to affect 100 million people worldwide. It has been observed to increase in prevalence when a population increases its plane of nutrition and decreases its energy expenditure. A striking example of this occurred when Ethiopian Jews were moved to Israel [l]. The Pacific(More)
Poor fetal growth is linked with long-term detrimental effects on health in adulthood. Here we investigate whether the lifespan of male mice is affected by their growth rate when they were suckling and find that limiting growth during that period not only increases longevity but also protects against the life-shortening effect of an obesity-inducing diet(More)
Epidemiological studies have revealed a relationship between early growth restriction and the subsequent development of type 2 diabetes. A rat model of maternal protein restriction has been used to investigate the mechanistic basis of this relationship. This model causes insulin resistance and diabetes in adult male offspring. The aim of the present study(More)
The present study examines the effects of late vs. early gestation undernutrition on adult glucose-insulin homeostasis in sheep and investigates whether the lower birth weight of twins alters glucose-insulin handling in adult life. Pregnant sheep were fed to requirement (100% intake) from day 0 of gestation to term [ approximately 147 days of gestation(More)
Cellular senescence has long been used as a cellular model for understanding mechanisms underlying the ageing process. Compelling evidence obtained in recent years demonstrate that DNA damage is a common mediator for both replicative senescence, which is triggered by telomere shortening, and premature cellular senescence induced by various stressors such as(More)
Maternal protein undernutrition can influence the growth and longevity of male offspring in the rat. We tested the hypothesis that these differences in longevity were associated with changes in the rate of telomere shortening. We found age-related shortening of telomeres in the liver and kidney but not in the brain of male rats. Growth retardation in(More)
