GH and IGF1 regulate cell proliferation, differentiation and apoptosis playing a key role in growth, and leading to consider potential oncogenic effects of GH. To evaluate possible oncogenic risks in GHD patients who underwent GH replacement therapy, the SAGhE consortium was created. The data collected have not yielded definite conclusions and continuous surveillance is yet required. MiRNAs are regulators of gene expression, and are involved in many biological processes. We ai...

Obesity is increasing, and the related complications are well known. Clinical Trials related with specific diets are currently lacking in paediatrics. There is an increasing interest in Mediterranean diet (MD). The Med4Youth European study* has enrolled 240, 13- to 16-year-old subjects with a BMI above the 90th percentile(WHO curves) in a multicenter randomized controlled trial (Italy, Spain and Portugal) to evaluate the effects of MD. We present the data relative to the 80 su...

Background: Klinefelter syndrome (KS) has long-term consequences on bone health. However, studies regarding bone status and metabolism in childhood and adolescence are very rare.Objective and hypotheses: The purpose of our study was to evaluate bone status and metabolism in a cohort of KS children and adolescents.Method: This cross-sectional study involves 40 (mean age 13.7±3.8 years) KS children and adolescents and 80 age-mat...

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 and Aims: Retesting subjects treated with GH throughout childhood at attainment of final height is of importance to identify those having pGHD and needing replacement treatment during transition years and adulthood, and to avoid overtreatment of GH sufficient subjects. This study aimed at evaluating the clinical and biochemical features of patients diagnosed of isolated idiopathic (II) GHD in childhood at retesting to verify the prevalence of perman...

Cerebral aneurysms and kidney disease in a child with microcephalic osteodysplastic primordial dwarfism type II: novel homozygous mutation in the PCNT gene.

Petraroli Maddalena , Percesepe Antonio , Piane Maria , Gnocchi Margherita , Messina Giulia , Lattanzi Claudia , D'alvano Tiziana , Dora Patianna Viviana , Ormitti Francesca , Maria Roberta Esposito Susanna , Elisabeth Street Maria

MOPD is known to be caused by homozygous loss-of-function mutations in a specific gene, PCNT. Both intra- and interfamilial clinical variability (even for the same variant) have been frequently observed, which makes it difficult to infer a genotype–phenotype correlation. Pericentrin (PCTN) is a structural protein expressed in the centrosome that plays a fundamental role in anchoring protein complexes, regulating mitotic cycle and thus cell proliferation. High levels of m...

CFTR Loss-of-Function has Effects on microRNAs (miRNAs) that Regulate Genes Involved in Growth, Glucose Metabolism and in Fertility in in vitro Models of Cystic Fibrosis

Cirillo Francesca , Catellani Cecilia , Graziano Sara , Montanini Luisa , Smerieri Arianna , Lazzeroni Pietro , Sartori Chiara , Marmiroli Nelson , Amarri Sergio , Gullì Mariolina , Elisabeth Street Maria

Cystic Fibrosis (CF), is due to CF-transmembrane-conductance-regulator (CFTR) loss-of-function. Significant heterogeneity exists between patients, suggesting potential epigenetic regulation, and comorbidities develop with time. MiRNAs are non-coding RNAs that act as epigenetic regulators. Although many studies have focused on the role for miRNAs in regulating CFTR gene expression, little attention has been given to how CFTR influences their expression and how this affects grow...

MicroRNAs Change and Target Key Regulatory Genes Involved in Longitudinal Growth in Patients with Idiopathic Isolated Growth Hormone Deficiency (IGHD) on Growth Hormone (GH) Treatment

Cirillo Francesca , Catellani Cecilia , Lazzeroni Pietro , Sartori Chiara , Ravegnini Gloria , Bonvicini Federico , Predieri Barbara , Amarri Sergio , Iughetti Lorenzo , Angelini Sabrina , Elisabeth Street Maria

The growth response in patients undergoing GH treatment is variable depending both on the patient's basal conditions and on personal innate sensitivity to therapy. MicroRNAs (miRNAs) are epigenetic regulators of gene expression, and are recognised as important regulators of biological and metabolic processes. It is unknown at present whether miRNAs could be early biomarkers of response to GH treatment in a perspective of individualised medicine, and whether they could disc...

Effect of the Melanocortin-4 Receptor Agonist, Setmelanotide, on Obesity and Hyperphagia in Individuals Affected by Bardet-Biedl Syndrome

Background: Bardet-Biedl syndrome (BBS) causes early-onset extreme obesity and hyperphagia that is hypothesized to arise from leptin receptor dysfunction. Setmelanotide, a melanocortin-4 receptor (MC4R) peptide agonist, has been shown to induce weight loss in individuals affected by other rare genetic obesity disorders resulting from leptin-melanocortin pathway dysfunction upstream of MC4R.Objective: Report preliminary data on body weight, hunger scores,...

High Mobility Group Box 1 (HMGB1) is Increased in Adolescents with Polycystic Ovarian Syndrome (PCOS) and Decreases after Treatment with Myo-Inositol in Combination with α-Lipoic Acid (MYO+ALA)

Cirillo Francesca , Catellani Cecilia , Tridenti Gabriele , Vezzani Cristina , Lazzeroni Pietro , Sartori Chiara , Fulghesu Anna Maria , Losi Simona , Coradazzi Letizia , Amarri Sergio , Street Maria Elisabeth

PCOS treatment in adolescence should aim at improving ovarian function, based on the pathophysiology of this condition. We previously described in cystic fibrosis and then in the PCOS an increase in HMGB1, secondary to reduced cystic fibrosis transmembrane conductance regulator (CFTR) expression in the ovary, associated with insulin resistance and inflammation that both characterize PCOS. Inositols and ALA derivatives are considered a good therapeutic option for their possible...
