Background: Recent studies in multiple models of type 1 diabetes mellitus (T1DM) have demonstrated the role of mitochondrial abnormalities in the pathogenesis of this disease and its complications. Humanin is a potent cyto-protective and ‘metaboloprotective’ molecule in vitro and in vivo, including the protection of β cells from apoptosis, improvements in insulin secretion and action, and both prevention and treatment of diabetes in the NOD mou...

Background: Genomic imprinting causes genes to be expressed or repressed depending on their parental origin. The 1-Mb DLK1-DIO3 imprinted domain is located on human chromosome 14. Gene expression along this cluster is regulated by an intergenic differentially methylated imprinting control region (‘IG-DMR’). In mice, altered gene dosage within this cluster is associated with alterations in embryonic and placental growth.Objective and hy...

Background: Maternal obesity can have long-term consequences for the offspring’s health, including increased risk of type-2 diabetes and cardiovascular disease. The C19MC imprinted locus on chromosome 19q13.4 comprises a cluster of 46 microRNAs, which are usually expressed only in the placenta and from the paternal allele exclusively. Besides its role favouring trophoblast migration, the C19MC locus is deregulated in several human cancers. It is unknown ...

Introduction:Up to 20% of children with neurofibromatosis type 1 (NF1) develops low-grade optic pathway gliomas(OPGs) that can result in neuroendocrinopathy.The aim of the study was to identify prognostic factors for developing neuroendocrinopathies in patients with NF1 and OPGs before any treatment.Methods: Records of 117 children with NF1 and OPGs followed at 4 Italian centers between 1997-20...

Introduction: Several studies show the negative impact of low level of studies of parents on the dietary patterns and the degree of adiposity of their children. The objective of this study is to evaluate the relationship between the level of studies and compliance with the recommendations of healthy eating pyramid.Material and method: An anthropometric study was conducted in 895 Spanish children and adolescents (53% women), between 3 and 18 years old (10...

Background: Pediatric bone marrow transplantation (BMT) can lead to endocrine dysfunctions due to common pre-operative regimens involving chemo and radiotherapy.Objective and hypotheses: To evaluate the prevalence an time-of-onset of endocrine dysfunctions after BMT in children and adolescents.Method: A retrospective cohort-study design was performed. The inclusion criteria were: <18 years of age at the time of their allogenic ...

Background and Aim: IRS1 (Insulin Receptor Substrate 1) is involved in the insulin signalling pathway and abnormalities thereof have been related to metabolic disorders and obesity. In obese subjects, insulin resistance has been associated with changes in IRS1 expression in peripheral in blood. Sex-based differences in cardiovascular disease are well established. Previous results from our group disclosed the association between IRS1 placental methylation with ...

Introduction: The CCDC3 gene encodes for a protein expressed in endothelial cells and adipose tissue. Insulin increases its expression and, in turn, CCDC3 positively regulates adipogenesis and lipid accumulation. CCDC3 expression is increased in visceral adipose tissue from subjects with obesity. Gestational obesity can modify the metabolic programming in the offspring through epigenetic mechanisms. However, it is unknown whether the...

Background: Turner Syndrome (TS) is a chromosomopathy affecting 1 out of 2000-2500 live births. Although short stature, heart disease and ovarian dysgenesis are the best-known features, patients have variable cognitive impairments. Aim of this study is to analyze the cognitive profile of a cohort of patients enrolled between February 2018-March 2023.Methods: 49 TS patients [Group A: 45, X0 (n=13); Group B: mosai...

Background: Central precocious puberty (CPP) results from activation of the hypothalamic-pituitary-gonadal axis before the age of 8 years in girls and 9 years in boys. The molecular basis of the maturation of this axis is still poorly understood. The MRKN3 gene located in the Prader-Willi syndrome critical region (chromosome 15q11–q13), inhibit factors stimulating pulsative. GnRH secretion. In 2013 inactivating mutations in the MRKN3 gene were discovered...
