Short stature due to a novel missense variant (695C>A) in the GHR gene: a case report.

Righi Beatrice , Trimarchi Gabriele , De Fanti Alessandro , Garavelli Livia , Sartori Chiara , Elisabeth Maria

Introduction: Laron Syndrome (LS) or primary growth hormone (GH) insensitivity is an autosomal recessive disorder due to variants in the GH-receptor (GHR) gene or to post-receptor defects. LS prevalence is estimated 1-9/1000000. We report a case of LS with a missense variant in the GHR gene not previously described.Case: female, Turkish, was referred to our clinic for short stature. Born at term, birth ...

Mir-146a and -155 are Involved in FOXO1 Regulation and Non Alcoholic Fatty Liver Disease in Childhood Obesity

Montanini Luisa , Lazzeroni Pietro , Sartori Chiara , Nobili Valerio , Crafa Pellegrino , Bernasconi Sergio , Street Maria E

Background: Non alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in childhood, in obese subjects and associated with insulin resistance.FOXO1 is a key regulator in insulin signalling and in intracellular adipogenesis, and is implicated in liver steatosis. We have previously identified that a group of miRNAs are involved in its epigenetic regulation.Objective and hypotheses: We aimed to assess in liver tissue and in serum whe...

Central Hypothyroidism as a manifestation of X linked IGSF1 Deficiency Syndrome: a case report

Righi Beatrice , Rosato Simonetta , Trimarchi Gabriele , Cattini Umberto , De Fanti Alessandro , Garavelli Livia , Elisabeth Street Maria , Sartori Chiara

Introduction: The IGSF1 gene deficiency syndrome (IDS) is an X-linked disorder involving hormonal disfunctions. We report a case of Central Hypothyroidism (CH) due to a Xq26.1q26.2 microdeletion including the IGSF1 gene.Case: this boy was referred to our clinic for thyroid dysfunction. He was born at term by caesarean section due to maternal uterine myoma. Pregnancy was normal, parents were non consangu...

The miRNA network and the interplay between growth and cancer regulating pathways in prepubertal patients with idiopathic isolated growth hormone deficiency (IGHD) on growth hormone (GH) treatment

Catellani Cecilia , Ravegnini Gloria , Sartori Chiara , Righi Beatrice , Poluzzi Silvia , Predieri Barbara , Iughetti Lorenzo , Angelini Sabrina , Elisabeth Street Maria ,

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...

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...

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...

High Mobility Group Box 1 (HMGB1) and Insulin-Like Growth Factor Binding Protein-2 (IGFBP-2) are Increased, Insulin Decreased and IL-6 Unchanged in Follicular Fluid (FF) from Polycystic Ovarian Syndrome (PCOS)

Cirillo Francesca , Catellani Cecilia , Lazzeroni Pietro , Sartori Chiara , Morini Daria , Nicoli Alessia , Amarri Sergio , La Sala Giovanni Battista , Street Maria Elisabeth

HMGB1 is a small-protein which reflects both inflammation and insulin-sensitivity. Inflammation and insulin-resistance are features of PCOS. IL-6 is important for ovarian function and can contribute to insulin-resistance. IGFBP-2 behaves like an acute-phase protein and is increased in chronic inflammation. It is also involved in the glucose-metabolism regulation and IGFBP-2 overexpression plays a protective role against insulin-resistance. Insulin functions as a co-gonadotropi...

Circulating miR146a and 486-5p are Altered in Obese Children with and Without Non-Alcoholic Fatty Liver Disease (NAFLD) and Correlate with Abdominal Fat and BMI

Montanini Luisa , Patianna Viviana D , Sartori Chiara , Predieri Barbara , Bruzzi Patrizia , Lazzeroni Pietro , Merli Silvia , Bergamaschi Paolo , Bernasconi Sergio , Iughetti Lorenzo , Street Maria Elisabeth

Background: MicroRNAs (miRNA) are small non coding RNA molecules, key regulators of metabolic pathways. Obesity is characterised by many metabolic changes. NAFLD is seen as a complication of obesity. FOXO-1, key regulator in insulin signalling, has been shown to be implicated in NAFLD. We previously identified miRNAs regulators of the FOXO-1 gene.Objective and hypotheses: To assess in serum whether the regulation of miR-146a and miR-486-5p, FOXO1 gene re...
