Apoptosis and Oxidative Stress Markers During the Oral Glucose Tolerance Test (OGTT)

Gil Andrea Paola Rojas , Katsa Maria Efthymia , Tzortzis Nomikos , Ioannidis Anastasios , Kostopoulou Eirini , Spiliotis Bessie E

Background: In adults, insulin resistance is associated with vascular damage and progressive loss of the endothelial protective functions. Additionally, it further complicates the micro- and macro- vascular environment through increasing oxidative stress and inflammation.Aim: The purpose of this study was to evaluate how apoptosis and antioxidant markers are correlated with biochemical markers in children, during the glucose tolerance te...

Association of Fasting Triglycerides to High-Density Lipoprotein Ratio with Risk for Metabolic Disorders in Children

Efthymia Katsa Maria , Ioannidis Anastasios , Zyga Sofia , Sachlas Athanasios , Tsironi Maria , Paola Rojas Gil Andrea

Background: Atherosclerosis begins in childhood and progresses silently. Triglycerides/HDL ratio(TG/HDL) is a risk factor for cardiovascular diseases.Objective and hypotheses: To investigate TG/HDL as possible predictive factor for metabolic disorders in children.Method: Descriptive correlation, with 110 children (6–12 years old) in Sparta, Greece. Anthropometric and biochemical analyzes were performed.R...

The Involvement of the Epidermal Growth Factor Receptor in the Successful GH Signalling and the Role of p21 in the Negative Regulation of the GH/GHR and EGF/EGFR Pathways, in GH Transduction Defect

Kostopoulou Eirini , Gil Andrea Paola Rojas , Karvela Alexia , Spiliotis Bessie Eugenia

Background: GH transduction defect (GHTD) is characterised by severe short stature and impaired STAT3 phosphorylation, which is overcome by simultaneous induction of GHTD fibroblasts with 200 ng/ml GH and short interference mRNA CIS (GH200/siRNA) or with 1 000 ng/ml GH (GH1000) and is clinically expressed with ‘catch-up’ growth after rhGH treatment.Objective and hypotheses: The involvement of epidermal growth factor receptor (EGFR) in the succe...

The Role of β-TrCP, an E3 Ubiquitin Ligase, in the Signalling of the GH and Epidermal Growth Factor Pathways in Growth Hormone Transduction Defect

Kostopoulou Eirini , Gil Andrea Paola Rojas , Karvela Alexia , Spiliotis Bessie Eugenia

Background: epidermal growth factor (EGF) stimulates cell growth and differentiation through its receptor EGFR. Cross-talking between the GH and EGF signaling pathways is important for normal cellular development. GH transduction defect (GHTD), a clinical disorder characterized by impaired STAT3 phosphorylation due to excessive GHR degradation, is caused by over-expression of the E3 ubiquitin ligase, CIS.Induction of GHTD fibroblasts with 200 ng/ml hGH (GH200) and silencing mR...

Oxidized lipid-associated protein damage in children and adolescents with type 1 diabetes mellitus: new diagnostic/prognostic clinical markers.

Kostopoulou Eirini , Kalaitzopoulou Electra , Papadea Polyxeni , Skipitari Marianna , Gil Andrea Paola Rojas , Spiliotis Bessie , Georgiou Christos ,

Background: Type 1 diabetes mellitus (DM1), a chronic metabolic disorder of autoimmune origin, has been associated with oxidative stress (OS), which plays a central role in the onset, progression and long-term complications of DM1. The markers of OS lipid peroxidation products, lipid hydroperoxides (LOOH), and also malondialdehyde (MDA) and thiobarbituric reactive substances (TBARS) that oxidatively modify proteins (Pr) (i.e., PrMDA and PrTBARS, respectively),...

Association of the apoptotic markers Apo1/Fas and cCK-18 and the adhesion molecule ICAM-1 with Type 1 diabetes mellitus in children and adolescents.

Kostopoulou Eirini , Efthymia Katsa Maria , Ioannidis Anastasios , Foti Maria , Dimopoulos Ioannis , Spiliotis Bessie , Paola Rojas Gil Andrea

Introduction: Type 1 diabetes mellitus (T1DM) is characterized by insulin-producing pancreatic β-cells loss. Apo1/Fas, a glycosylated surface protein, is implicated in maintaining homeostasis of the immune system. Cytokeratin-18 (cCK-18) is a predictive marker of liver disorders in T2DM. Intercellular adhesion molecule-1 (ICAM-1) is considered a candidate gene for susceptibility to diabetes mellitus. Aim: To investigate the possible role of Apo1/Fas, cCK-...

Bone Homeostasis in Children with Subclinical Hypothyroidism: Effects of Two-years Treatment with Levothyoxine

Barbieri Flavia , Esposito Andrea , D'Acunzo Ida , Lorello Paola , Di Mase Raffaella , Improda Nicola , Capalbo Donatella

Background: Thyroid hormone plays a key role in bone mineral homeostasis and significant alterations in its circulating levels have been associated with an impairment in skeletal growth during childhood. To date, the effects of subclinical hypothyroidism (SH) on bones have not been studied and the management of this condition is still debated.Aim: To evaluate bone mineral density (BMD) in children with mild, persistent S...

Serum Anti-Mullerian Hormone (AMH) concentrations and Reduced Appendix Testis Estrogen Receptor Expression in Cryptorchidism

Panagidis Antonios , Kourea Helen , Sinopidis Xenophon , Kostopoulou Eirini , Rojas-Gil Andrea Paola , Skiadopoulos Spyridon , Georgiou George , Spiliotis Bessie E.

Objective: AMH causes fetal paramesonephric duct regression and is involved in testicular development and function. Sertoli cell AMH remains high during childhood until puberty. The appendix testis (AT), a remnant of the paramesonephric duct, contains both androgen and estrogen receptors. AT androgen receptors have been reported to play a role in embryonic testicular descent. The AT is commonly resected during orchiopexy and abdominal surgery as possible torsion in the future ...
