Introduction: A low oxygen and/or nutrient supply to the fetus, resulting in intrauterine growth restriction (IUGR), can affect gonadal development of the offspring and have a potential impact on fertility. Epidemiological studies on subjects born small for gestational age (SGA), as a surrogate measure of IUGR, have reported contradictory results. Data derived from animal models of placental insufficiency are limited.Objective and hypotheses: To investig...

Background: Endoplasmic reticulum (ER) is the site where proteins are folded in the cell. Metabolic stress alters ER homeostasis and activates the unfolded protein response (UPR), which contributes to the development of insulin resistance and metabolic syndrome.Objective and hypotheses: To longitudinally evaluate liver UPR and its functional consequences in an animal model of IUGR followed from birth to adulthood.Method: On day 19 ...

Background: Fetuin A is a hepatokine known as a natural inhibitor of the insulin receptor tyrosine kinase and is associated with insulin resistance and nonalcoholic fatty liver disease (NAFLD). Studies on adults provided conflicting results regarding the link between fetuin A and the severity of liver damage in NAFLD. Data on children are limited.Objective: To investigate the relationship between fetuin A, metabolic parameters, and NAFLD in obese childre...

Background: Endoplasmic reticulum (ER) is the site where proteins are folded. Perturbation of ER homeostasis activates a set of ER-to-nucleus signaling reactions known as the unfolded protein response (UPR). Metabolic stress causes UPR activation which contributes to the development of insulin resistance and metabolic syndrome. As UPR can be activated by nutrient and oxygen starvation, we postulated that intrauterine growth restriction may trigger UPR signaling and thereby con...

Background: The influence of intrauterine life on long term health is supported by a wealth of epidemiological and experimental studies. A low oxygen and/or nutrient supply to the fetus, resulting in intrauterine growth restriction (IUGR), may affect gonadal development of the offspring, with a potential impact on fertility. Data derived from animal models of placental insufficiency are very limited.Objective and hypotheses: To investigate the effects of...
