Introduction: Neutrophil/lymphocyte (N/L) ratio is considered as a sign of systemic inflammation in recent years. In our study, we aimed to investigate N/L ratio in hyperthyroid patients and healthy control group.Material & methods: A total of 121 hyperthyroid patients (71 patients with Graves’ disease and 50 patients with other causes of hyperthyroidism) and 40 healthy volunteers were enrolled. Complete blood count was obtained from both group ...

A gene causing autosomal dominant kyphoscoliosis in an N-ethyl-N-nitrosourea (ENU) mutagenised mouse model is located on a 5 Mb interval on mouse chromosome 4 band A3

Kyphosis and scoliosis are common spinal disorders that lead to significant morbidity in childhood, adolescence and adulthood. Familial and twin studies have implicated a genetic involvement, although the causative genes remain to be identified. To facilitate these studies, we investigated 12-week-old progeny of mice treated with the chemical mutagen N-ethyl-N-nitrosourea (ENU) using phenotypic assessments that included dysmorphology, radiography and dual-energy ...

Promotion of thyroid cancer cell migration and invasion by the proto-oncogene PBF is mediated by FGD1 and N-WASP

Manivannan Selvambigai , Alshahrani Mohammed , Thornton Caitlin EM , Raja Saroop , Kocbiyik Merve , Zha Ling , Brookes Katie , Nieto Hannah R , Read Martin L , McCabe Christopher J , Smith Vicki E

Thyroid tumor progression is dependent on cell motility, a highly complex process that involves the co-ordination of cell adhesion, actin dynamics and signal transduction. The proto-oncogene pituitary tumor-transforming gene (PTTG)-binding factor (PBF/PTTG1IP) is a transmembrane glycoprotein that is overexpressed in thyroid cancer and associated with a poorer prognosis. PBF significantly promotes thyroid cancer cell migration and invasion through phosphorylation at PBF-Y174 by...

The (CAG)n repeat polymorphism of the androgen receptor gene is associated with bone mineral density in menopausal women

Markatseli Anastasia , Lazaros Leandros , Kostoulas Harilaos , Markoula Sofia , Tigas Stelios , Georgiou Ioannis , Tsatsoulis Agathocles

Introduction: Osteoporosis is a systemic skeletal disease with a strong genetic component. The androgen receptor (AR) is encoded by the AR gene and mediates the action of androgens, which play an important role in bone metabolism. Polymorphisms in the AR gene may be implicated in the pathogenesis of osteoporosis.Objectives: The present study aimed to explore the influence of the (CAG)n repeat polymorphism of AR</em...

Comparison of urinary N-Acytyl β-D glucoseaminidase activity in diabetic patients and controls

Hesabi ZB , Salimi S

Urinary N-Acytyl β-D glucoseaminidase EC: 3.2.1.31 is a lysosomal enzyme which is classified in hexosaminidases group. This enzyme is found in different tissues such as, kidney, liver and spleen, but the kidney has maximum level of enzyme.The first step was the standardization of colourimetry and flourimetry of enzyme assay. In colourimerty method para-nitrophenyl N-acetyl β-D-glucosamine is used as substrate and in flourimetry method the subst...

Association of the (TTTA)n repeat polymorphism of CYP19 gene with bone mineral density in Greek peri- and postmenopausal women

Markatseli Anastasia , Lazaros Leandros , Kostoulas Harilaos , Sakaloglou Prodromos , Markoula Sofia , Tigas Stelios , Georgiou Ioannis , Tsatsoulis Agathocles

Introduction: Aromatase is encoded by the CYP19 gene and catalyzes the conversion of androgens to estrogens, which in turn regulate skeletal homeostasis. Polymorphisms in the CYP19 gene have been studied for their association with bone mineral density (BMD) in the general population with mixed results.Objectives: To explore the influence of the CYP19 (TTTA)n repeat polymorphism on BMD and serum levels of osteoprotegerin (OPG), receptor activator...

Effect of amino acid residues on N-terminal extension of GLP-1/IgG-Fc fusion protein

Lee C , Boyineni J , Chung H-S , Jang S-H

Glucagon-like peptide-1 (GLP-1) is an incretin hormone playing an important role in glucose-dependent insulin secretion and β-cell growth. However, GLP-1 is rapidly degraded by dipeptidyl peptidase IV (DPP-IV) in vivo. Many attempts have been made to develop long-acting GLP-1 analogs with chemical modification, amino acid substitution, and fusion protein technology. We previously showed that the N-terminal Ala- or Gly-extended GLP-1 and human immunoglobulin ...

N-acetylmuramoyl-L-alanine amidase is a biomarker for remission of type 2 diabetes after bariatric surgery

Iqbal Zohaib , Fachim Helene , Gibson John , Baricevic-Jones Ivona , Campbell Amy , Geary Bethany , Donn Rachelle , Syed Akheel , Wetton Anthony , Soran Handrean , Heald Adrian

Aims: We used sequential window acquisition of all theoretical fragment ion spectra Mass Spectrometry (SWATH-MS) to identify proteins acting as markers of remission of type 2 diabetes (T2DM) in patients who lost weight after bariatric surgery.Background: Bariatric surgery results in remission of T2DM in up to 80% of patients. The mechanisms underpinning are largely unknown. N-acetylmuramoyl-L-alanine amidase (PGLRYP2) is an immune response enzyme that br...

The (TAAAA)n polymorphism in the SHBG gene is related to prenatal androgenization of female fetus: possible implications of the developmental origin of metabolic disorders

Pamporaki Christina , Xita Nectaria , Lazaros Leandros , Makridimas George , Georgiou Ioannis , kolios George , Plachouras Nikolaos , Tsatsoulis Agathocles

Introduction: The aim of this study was to examine whether the distribution of SHBG (TAAAA)n repeat variants contributes to the exposure of the female fetus to androgen excess, by influencing the, in utero, androgen availability.Methods: The study population consisted of 100 pregnant women that carried female fetuses and underwent the procedure of amniocentesis due to age (older than 35). Blood samples and amniotic fluid samples were dr...

The effects of di(n-butyl) phthalate (DBP) exposure on testis cell development/function in human fetal testis xenografts

Mitchell Rod , Childs Andrew , Anderson Richard , van den Driesche Sander , McKinnell Chris , MacPherson Sheila , Wallace W , Kelnar Chris , Saunders Philippa , Sharpe Richard

Background: Endocrine disruption in the human fetal testis by environmental agents has been proposed as a possible cause of testicular dysgenesis syndrome (TDS) comprising male reproductive disorders such as testicular germ cell tumours (TGCT), cryptorchidism, hypospadias and low sperm counts. Exposure of fetal rats to the widely used plasticizer di(n-butyl) phthalate (DBP) results in a TDS-like syndrome due to a reduction in testosterone production. Whether such effects also ...
