Insulin-like growth factor (IGF) 2 plays a fundamental role in prenatal growth and development. The IGF2 gene is imprinted, with the paternally inherited copy being active and the maternal copy being silenced in most tissues. During development, the expression of IGF2 is sexually dimorphic in some tissues and this is thought to be involved in the development of some sexually dimorphic features. For example, IGF2 expression is reported to be higher in the male brain co...

Background: The majority of drug developments in type 1 diabetes (T1D) are aimed at preventing decline of beta cell function (BCF), as this has been associated with better glycaemic control and fewer long-term complications. Traditionally, BCF is evaluated by the C-peptide response to the labour-intensive mixed-meal-tolerance-test (MMTT), but there’s a need for a more practical alternative. We developed a new method to measure C-peptide in ‘dried blood spots’ (D...

Background: Trabecular Bone Score (TBS) is a software-based tool for analysis of DXA images to assess bone microarchitecture in the lumbar region. Several studies have addressed its value in adult population, however, little research has been done in children in which may be useful for bone evaluation during growth.Objective: To evaluate bone density and TBS during childhood and its relationship to other variables such as bone age and height<p class=...

Background: The goal of treatment in children with hypophosphatemic rickets (HR) attempts to correct growth and leg deformities. However, growth is compromised despite treatment and patients are at risk of developing nephrocalcinosis in the future. Some factors (sex, age and height at diagnosis) have been related to height outcome, but little is known about the impact in growth of different dosage of treatment or alkaline phosphatase (ALP) levels.Objecti...

Background: Oligo-ovulatory androgen excess in women (polycystic ovary syndrome (PCOS) by NIH definition) is a major cause of subfertility and relates to hepatic steatosis, independently of obesity.Objective: To test whether early treatment of PCOS affects subsequent ovulation rate.Method: Adolescent girls with hyperinsulinemic androgen excess – a subgroup of PCOS – (mean age 16 year; BMI 23.7 kg/m2) randomly r...

Background: Fetal growth is partly regulated by epigenetic factors, such as DNA methylation. Altered methylation status in placental genes relates to gestational diabetes, preeclampsia and prematurity. However, the epigenetic mechanisms underlying fetal growth restraint in uncomplicated pregnancies remain unknown.Objective and hypotheses: We aimed at identifying new candidate genes related to fetal growth, by assessing DNA methylation profiling in placen...

Background: Neonatal over-nutrition (NON) can increase the propensity to become overweight and develop associated metabolic disturbances in later life. Moreover, some of these long-term effects are sexually dimorphic.Objective and hypotheses: We aimed to determine how NON affects body weight (BW), body composition and triglyceride (TG) and non-esterified fatty acids (NEFA) levels. We hypothesized that the effects would be both age and sex dependant.<...

Background: Circadian disorganization of feeding behavior evoked by high fat diet (HFD) intake is suggested to be involved in the resulting weight gain and development of associated metabolic alterations and hypothalamic inflammation.Hypothesis: We hypothesized that this circadian alteration might be a consequence of rapid de-synchronization of different gene clusters relevant for metabolic control.Methods: We analyzed the circadia...

Background: Diabetes is associated with increased risk of vascular disease. In children and adolescents with type 1 diabetes (T1D), clinical manifestations of vascular complications are infrequent; however, a pro-inflammatory state and endothelial disturbance could appear early. A subclinical inflammation state result in increased plasma levels of adhesion molecules, inflammatory cytokines as tumor necrosis factor alpha (TNFα), and acute phase proteins as C-reactive prote...

Introduction: Obesity is known to associate with chronic systemic inflammation. However, hypothalamic inflammation also occurs in response to high fat diet (HFD)-induced obesity and is proposed to participate in central insulin/leptin resistance and the perpetuation of weight gain and systemic affectation. The weight gain and central responses to HFD differ between males and females. As hypothalamic glial cells are implicated in the central inflammatory response we hypothesize...
