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) 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...

Background: Over the years special screening procedures for preterm and twin babies (re-screening at 2–4 weeks of life) have been adopted by many screening laboratories worldwide. However, no extensive studies have been performed to verify how many co-twins with negative test at first screening (3–5 days) become positive at re-screening, and the utility of a long-term follow-up also in co-twin with negative test at screening and re-screening.Ob...

Clinical Findings, Endocrine Profile and Genetic Features of 5α-Reductase-2 Deficiency

Russo Gianni , Baldinotti Fulvia , Ghirri Paolo , Meroni Silvia , Colombo Ilaria , Moscuzza Francesca , Baroncelli Giampiero I , Sessa Maria R , Dati Eleonora , Bertelloni Silvano

Background: The 5α-reductase-2 (5R2) deficiency is a rare 46, XY disorder of sex differentiation caused by mutations in the 5R2 gene. Diagnostic and clinical management is not well definite.Aims and objectives: To describe relevant features of 5R2 deficiency in a large sample.Methods: Retrospective records of persons with 5R2 deficiency were reviewed and clinical, endocrinological, genetic data analysed....

Short stature in Protein Arginine Methyltransferase 7 (PRMT7) mutations: first evidences of growth response to rGH treatment

Protein arginine methyltransferase 7 (PRMT7), a member of a family of enzymes that catalyse the transfer of methyl groups from S-adenosyl-L-methionine to nitrogen atoms on arginine residues, is involved in multiple biological processes, such as signal transduction, mRNA splicing, transcriptional control, DNA repair, and protein translocation. Currently, 12 patients with homozygous/compound heterozygous mutations in PRMT7 gene have been described defining the ...

Serum high mobility group box 1 (HMGB1) levels are independently associated with glucose clamp-derived measures of insulin resistance in PCOS

Catellani Cecilia , Migazzi Matteo , Sartori Chiara , Dauriz Marco , Righi Beatrice , Cirillo Francesca , Villani Michela , Tosi Flavia , Moghetti Paolo , Street Maria Elisabeth

Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age, and is characterised by chronic inflammation and in most cases by insulin resistance besides ovulatory dysfunction and hyperandrogenism. HMGB1 is a small protein with cytokine activity that can activate nuclear factor kappa light chain enhancer of activated B cells (Nf-kB), and signals through the Receptor for advanced glycation end products (RAGEs) and through the T...

Dual-X-ray-Absorptiometry (DXA) bone parameters in children with Achondroplasia

Angelelli Alessia , Fava Daniela , Elsa Maria Allegri Anna , Casalini Emilio , Napoli Flavia , Ridella Francesca , Tedesco Caterina , Maghnie Mohamad , Di Iorgi Natascia

Achondroplasia is the most common skeletal dysplasia caused by a gain of function of the fibroblast growth factor receptor 3(FGFR3) that impairs endochondral ossification, exiting in short stature and altered bone microarchitecture. Although fractures and reduced bone mineralization are not comorbidities frequently reported, specific normative DXA data are lacking. Aim of the study was to assess bone density parameters in an Achondroplasia cohort. Fifty-seven patients (Female-...

Ontogeny of FGF21 in the Human: Implications for Metabolic Health

Villarroya Francesc

Background: FGF21 is a hormonal factor with powerful anti-diabetic and anti-obesity properties in adults\. Studies in rodent models indicated that hepatic FGF21 expression and blood FGF21 levels are strongly induced after birth in response to fat provided by milk ingestion. Moreover, preliminary data indicate that FGF21 is present in maternal milk.Objective and hypotheses: Our objective is to determine, using human samples and pre-clinical experimental m...

The Endocrine Role of Brown Adipose Tissue

Villarroya Francesc

Background: The endocrine role of white adipose tissue (WAT), as a site of release of the so-called adipokines, has been recognized for long. Brown adipose tissue (BAT) is the main site of adaptive thermogenesis in mammals, especially relevant in neonates and early infancy. The amount and activity of BAT are associated with a healthy metabolic profile and protection against obesity, type II diabetes and hyperlipidemia. This biological role of BAT is traditionally attributed to...
