Background: Children born small for gestational age (SGA) are at increased risk of coronary heart disease and type 2 diabetes in adulthood, due to reprogramming of endocrine and metabolic functions. Dysregulation of specific miRNAs in response to genetic and environmental factors contribute to aberrant gene expression patterns underlying metabolic dysfunction.Objective and hypotheses: We aimed to identify miRNAs associated with increased risk of obesity ...

Background: 25-OH vitamin D levels in newborns depend directly on their mother’s status. In a previous study, 25-OH vitamin D levels were determined in cord blood in a cohort of women after winter months, showing deficient values in 94% of population (mean 25-OH vitamin D value 10.4±6.1 ng/ml). Correlation between low 25-OH vitamin D levels and low sun exposure, dark skin phototype and Indo-Pakistani ethnicity were observed.Objective and hypoth...

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...

Iodide (I−) transport defect (ITD) is an autosomal recessive disorder caused by the inability of the thyroid follicular cell to actively accumulate iodide. Active I− accumulation is mediated by the Na+/I− symporter (NIS), an integral plasma membrane glycoprotein located on the basolateral surface of thyrocytes. The diagnostic criteria for ITD include a variable degree of hypothyroidism and goiter, low to absent thyr...

Objective: Recent experimental data suggest that circulating serotonin interacts with bone metabolism, although this is less clear in humans. This study investigated whether serum serotonin interferes with bone metabolism in young women with anorexia nervosa (AN), a clinical model of energy deprivation.Methods: Serum serotonin, markers of bone turnover (osteocalcin (OC), procollagen type 1 N-terminal propeptide (PINP), type 1-C telopeptide breakdown prod...

Purpose: Low areal bone mineral density (aBMD) is a well-known consequence of anorexia nervosa (AN). However, the impact of reduced energy expenditure on bone metabolism is unknown. This study assessed the effects of energy deficiency on bone remodelling and its potential interactions with glucose homeostasis and adipose tissue-derived hormones in AN, a clinical model for reduced energy expenditure.Methods: 50 women with AN and 50 age-matched controls (m...

Background and Aims: HNF4A-MODY clinical expression is broad, ranging from hypoglycemic hyperinsulinism in the neonatal period and early childhood to hyperglycemia and diabetes, as insulin secretion progressively decreases in adult patients. The main objective was to clinically and molecularly characterize patients with glycemic alterations, negative autoimmunity and confirmed molecular diagnosis of HNF4A-MODY.Materials and Metho...
