Introduction: Insulin (INS) gene is reported to be the most important gene involved in Type 1 Diabetes (T1D); its expression is inversely correlated with methylation at CpG sites. Hypermethylated primers are associated with decreased expression.Aim: The present study aims to investigate possible differences in DNA methylation pattern between T1D youngsters and healthy controls.Patients and Methods: Twenty T1D parti...

Introduction: HLA-G gene is involved in the control of immune response. It plays a primary role on immune tolerance and may participate in controlling autoimmune responses serving as a potential independent susceptibility marker. HLA-G has been isolated in some secretory granules and on the cell surface of primary islet cells induced to secrete insulin. Subsequently, it could be hypothesized that HLA-G methylation at pancreatic islet could sustain T cell activation and onset o...

Lessons from Wolfram Syndrome: Initiation of DDAVP Therapy Causes Renal Salt Wasting due to Elevated ANP Levels, Rescued by Fludrocortisone Treatment

Background-Hypothesis: Sudden initiation of treatment for diabetes insipidus (DI) with DDAVP causes abrupt volume expansion resulting in particularly high secretion of Atrial Natriuteric Peptide (ANP) (1). ANP blocks all stimulators of zona glomerulosa steroidogenesis, resulting in secondary mineralocorticoid deficiency and acute hyponatremia, causing renal salt wasting (RSW) (2). Cases: Two sisters, a 19-year-old girl (A) and a 7-year-old girl (B) with Wolfra...

Background: Protein subfamilies within the Nuclear receptor (NR) family share common domain architecture. These closely related receptors and their cognate ligand compounds play a key role in homeostasis, reproduction, growth, and development. Despite their biological significance, their evolution and diversification remains to be elucidated. SNPs and mutations are characterized by the permanent alteration of the nucleotide sequence in the genome of an organism. These alterati...

Kyritsi Eleni Magdalini , Nicolaides Nicolas C , Lamprokostopoulou Agaristi , Xaidara Athina , Georgiadou Elizabeth , Dimitropoulou Vassiliki , Stefa Alketa , Sertedaki Amalia , Chrousos George P , Charmandari Evangelia

Background: Transient Generalized Glucocorticoid Hypersensitivity (TGGH) is a rare disorder characterized by increased tissue sensitivity to glucocorticoids and compensatory hypoactivation of the hypothalamic–pituitary–adrenal (HPA) axis. The condition itself and the underlying molecular mechanisms have not been fully elucidated.Objective and hypotheses: To present the clinical manifestations, endocrinologic evaluation and molecular studies in ...

Search for Genetic Defects in the Transcription Factor Genes FOXL2, FOXE1, BMP15, NOBOX, and GDF9 in Children, Adolescents and Young Adults With Premature Ovarian Insufficiency POI

Background: Molecular defects are rarely detected in Premature ovarian insufficiency (POI) patients.Objective and Hypotheses: We hypothesized that the frequency of causative molecular defects could be higher in cases with early onset of POI. Moreover, the analysis of multiple genes in the same POI group could disclose co-existence of more than one molecular aberration.Method: In 25 subjects, aged 17.1±7 years at POI onset, bid...
