Background Obesity has long been a severe threat to public health as an epidemic, and studies on its pathogenesis and treatment have been ongoing. Our study aims to compare the serum levels of bone morphogenetic protein 1 (BMP1), neuregulin 4 (NRG4), and apolipoprotein A5 (ApoA5) in obese and non-obese individuals and investigate their association with obesity. Methodology Our study included a total of 111 participants, of whom 46 were obese (body mass index (BMI) ≥30 kg/m), aged 18-65 years, and had no comorbidities, and 65 were non-obese (BMI = 18.

Background: Although patients with coronary artery disease (CAD) have a high mortality rate, the pathogenesis of CAD is still poorly understood. During the past decade, microRNAs (miRNAs) have emerged as new, potential diagnostic biomarkers in several diseases, including CAD. This study aimed to investigate the expression profiles of miRNAs in individuals with CAD and non-CAD.

Impact of Autoimmune Demyelinating Brain Disease Sera on Pericyte Survival.

Noro Psikiyatr Ars

June 2021

Neuroscience Department, Aziz Sancar Institute for Experimental Medicine, İstanbul University, İstanbul, Turkey.

Article Synopsis
  • Multiple sclerosis (MS) is an autoimmune condition that affects the central nervous system, leading to issues like demyelination and problems with brain pericytes, which may play a role in the disease's development.
  • The research involved using mice to induce a model of MS and examined how serum from these mice and human patients impacted the survival of human brain vascular pericyte (HBVP) cells, using various testing methods.
  • Findings indicated that sera from mice with MS and from MS patients led to increased early apoptosis and reduced survival of HBVP cells, suggesting that factors in serum may influence the dysfunction of pericytes in progressive forms of MS.

[Association of APOA5-1131T>C polymorphism with obesity in coronary artery disease].

Turk Kardiyol Dern Ars

July 2020

Department of Genetics, Aziz Sancar Institute for Experimental Medicine, Istanbul University, İstanbul.

Objective: Genetic risk factors that cause coronary artery disease (CAD) demonstrate variations in different populations. In this study, a single nucleotide polymorphism in the APOA5 gene was targeted to determine genetic contributors to atherosclerotic CAD. The effects of this polymorphism on the development of CAD and known risk factors of the disease were examined.

Progranulin (GRN) gene mutations are a major cause of frontotemporal dementia (FTD). Most mutations identified to date are null mutations, which are predicted to cause the pathology via haploinsufficiency. Decreased peripheral progranulin protein (PGRN) levels are associated with the presence of GRN null mutations and are accepted as reliable biomarkers.
