Suboptimal developmental environments program offspring to lifelong metabolic problems. The aim of this study was to determine the impact of protein restriction in pregnancy on maternal liver lipid metabolism at 19 days of gestation (dG) and its effect on fetal brain development. Control (C) and restricted (R) mothers were fed with isocaloric diets containing 20 and 10% of casein. At 19 dG, mat...

BACKGROUND There is growing evidence that disturbances in maternal metabolism and, subsequently, intrauterine conditions affect foetal metabolism. Whether this has metabolic consequences in offspring later in life is not fully elucidated. We investigated whether maternal pre-pregnancy body mass index (pBMI) is associated with offspring's adiposity at age 5-6 years and whether this association i...

OBJECTIVE Factors associated with increasing maternal triglyceride concentrations in late pregnancy include gestational age, obesity, preeclampsia, and altered glucose metabolism. In a subgroup of women in the Metformin in Gestational Diabetes (MiG) trial, maternal plasma triglycerides increased more between enrollment (30 weeks) and 36 weeks in those treated with metformin compared with insuli...

BACKGROUND Excessive gestational weight gain (GWG) increases risk of large for gestational age neonates and subsequent tracking of excess weight throughout the life course for both mother and child. Although the physiological mechanisms underlying these associations are incomplete, the insulin-like growth factor (IGF) axis has garnered attention for its role in fetal growth and development. Our...

Increasing evidence suggests that undernutrition during the fetal period may lead to glucose intolerance, impair the insulin response and induce insulin resistance (IR). Considering the importance of chromium (Cr) in maintaining carbohydrate metabolism, the present study aimed to determine the effects of maternal low Cr (LC) on glucose metabolism in C57BL mice offspring, and the involved mechan...

BACKGROUND Given the long-term adverse sequelae of childhood obesity, identification of early life factors related to fetal growth and childhood obesity is warranted. Investigation on growth and obesity in early life in association with intrauterine exposure to maternal hyperglycemia, a common metabolic pregnancy complication, is of public health significance and clinical implications. OBJECT...

background: in 2-4% of couples in fertile ages, recurrent pregnancy loss (rpl) occurs which consisted one out of 300 pregnancies. the aim of this study was to comparison insulin resistance (ir) in patients with rpl to normal individuals. materials and methods: in a case-controlled, prospective study, 49 non-pregnant, non-diabetic women with early rpl as the case group and 49 non-pregnant, non-d...

Maternal stress and malnutrition modify intrauterine fetal development with impact on postnatal blood pressure, nutrient, water, and electrolyte metabolism. The present study explored the possible involvement of maternal serum- and glucocorticoid-inducible kinase (SGK)-1 in fetal programming of blood pressure. To this end, wild-type (sgk1(+/+)) male mice were mated with SGK1 knockout (sgk1(-/-)...

During development there is novel expression of NPY mRNA in the dorsomedial hypothalamic nucleus (DMH) and perifornical region (PFR), in addition to the arcuate nucleus (ARH). Furthermore, NPY mRNA levels peak in all regions on postnatal d 16 (P16) and decrease to adult levels by P30. The purpose of the present study was to determine whether NPY and agouti-related protein (AGRP) mRNA expression...

We examined whether low-dose dexamethasone administration during late pregnancy modifies hepatic and/or peripheral insulin action or glucose-stimulated insulin secretion. Dexamethasone (100 microg/kg maternal body weight/d) was administered via an osmotic minipump from d 14--19 of gestation. Maternal glucose-insulin homeostasis was assessed on d 19 of pregnancy in the postabsorptive state. Insu...
