miR-320a promotes p53-dependent apoptosis of prostate cancer cells by negatively regulating TP73-AS1 invitro.

TP73 antisense RNA 1 (TP73-AS1) is an oncogenic long non-coding RNA that is activated in several types of cancers. It has been shown that the activity of TP73-AS1 is controlled by several miRNAs, but post-transcriptional mechanisms that regulate TP73-AS1 activity in prostate cancer remain highly elusive. Accordingly, in the present study, we aimed to determine the miRNAs that are involved in the regulation of TP73-AS1 in prostate cancer and to show the effects of these molecules on the malignant proliferation of prostate cancer cells.

Silencing of TP73-AS1 impairs prostate cancer cell proliferation and induces apoptosis via regulation of TP73.

Background: Prostate cancer is a malignant disease that severely affects the health and comfort of the male population. The long non-coding RNA TP73-AS1 has been shown to be involved in the malignant transformation of various human cancers. However, whether TP73-AS1 contributes to prostate cancer progression has not been reported yet.

Clinical and molecular evaluation of MEFV gene variants in the Turkish population: a study by the National Genetics Consortium.

Familial Mediterranean fever (FMF) is a monogenic autoinflammatory disorder with recurrent fever, abdominal pain, serositis, articular manifestations, erysipelas-like erythema, and renal complications as its main features. Caused by the mutations in the MEditerranean FeVer (MEFV) gene, it mainly affects people of Mediterranean descent with a higher incidence in the Turkish, Jewish, Arabic, and Armenian populations. As our understanding of FMF improves, it becomes clearer that we are facing with a more complex picture of FMF with respect to its pathogenesis, penetrance, variant type (gain-of-function vs.

Investigation the Relationship of Autism Spectrum Disorder and Genes.

Introduction: Autism spectrum disorder is a genetically and phenotypically heterogeneous group. Genetic studies carried out to date have suggested that both common and rare genetic variants play a role in the etiology of this disorder. In our study, we aimed to investigate the effect of and gene variants in the pathogenesis of autism spectrum disorder.

Genetic screening results of individuals with high risk BRCA-related breast/ovarian cancer in Trakya region of Turkey.

Purpose: Pathogenic/likely pathogenic (P/LP) germline variations in BRCA1 and BRCA2 genes are responsible for the majority of hereditary breast and ovarian cancers. This study presents the BRCA1/BRCA2 sequencing and deletion duplication analyses results of of 493 participants (485 women, 8 men) selected based on the National Comprehensive Cancer Network (NCCN) guidelines.

Methods: Next generation sequencing (NGS) and multiplex ligation-dependent probe amplification methods (MLPA) were used to define germline BRCA1/BRCA2 positivity.

Next generation sequencing analysis of BRCA1 and BRCA2 identifies novel variations in breast cancer.

Mutations in two major breast cancer susceptibility genes, BRCA1 and BRCA2, have been identified to be the most important predisposing factors for the development of breast cancer. Thus, BRCA1/2 testing is a well-established method of choice for the assessment of developing breast cancer. Accordingly, here we aimed to report novel BRCA1/2 variations and distribution of previously known mutations and their association with the clinical course of breast cancer disease.

Targeted next-generation sequencing as a diagnostic tool in gastrointestinal system cancer/polyposis patients.

Investigation of Copy Number Variation by arrayCGH in Turkish Children and Adolescents Diagnosed with Autism Spectrum Disorders.

Aim: The development of whole-genome screening methodologies for the detection of copy number variations (CNVs), such as array-based comparative genomic hybridization (aCHG), provides a much higher resolution than karyotyping leading to the identification of novel microdeletion and microduplication syndromes often associated with an autism spectrum disease (ASD) phenotype. The aim of the study was to determine CNVs of patients with ASD by using array-based comparative genomic hybridization.

Methods: Fifty-three patients diagnosed with ASD between 20.

Objective: We studied CXCL12-related rs18011157 polymorphism in non-Hodgkin lymphoma (NHL) patients. We also determined the effect of this polymorphism on clinical features and outcome of NHL.

Methods: We included 90 NHL patients (54 males, 36 females) and 88 healthy controls (54 males, 34 females).

Nonoccupational Exposure of Agricultural Area Residents to Pesticides: Pesticide Accumulation and Evaluation of Genotoxicity.

Although many studies related the toxic effects of pesticides on agricultural workers, little research has been done about agricultural area residents. The purpose of this work was to monitor the presence of pesticides, as well as their genotoxic and cytotoxic potential, in humans with blood samples collected from control and intensive agricultural areas in the Thrace region. Pesticide accumulations were determined by LC-MS/MS.

BRAF V600 Mutation Profile of Metastatic Melanoma in the Thrace Region of Turkey.

Objective: BRAF is the most common mutation in melanoma. The most common subtype is BRAF V600E, followed by V600K. Initially, the authors aimed to investigate whether clinicopathological features of melanoma are associated with BRAF mutations.

Genetic Analyses of the Gene in Turkish Neurofibromatosis Type I Patients and Definition of three Novel Variants.

Neurofibromatosis Type I (NF1) is a multi systemic autosomal dominant neurocutaneous disorder predisposing patients to have benign and/or malignant lesions predominantly of the skin, nervous system and bone. Loss of function mutations or deletions of the gene is responsible for NF1 disease. Involvement of various pathogenic variants, the size of the gene and presence of pseudogenes makes it difficult to analyze.

Cytotoxic Antibody Detection by Means of Flow-Cytometric Cross-Match.

Background: Complement-dependent lymphocytotoxicity (CDC-XM) and flow-cytometric (FCXM) cross-match are analyzed individually for each donor and recipient pair, because these techniques have fundamental differences for the evaluation of histocompatibility. Lately, cytotoxic flow-cytometric cross-match (cFCXM) has been developed as an alternative to both CDC-XM and FCXM techniques. We evaluated the limits of cFCXM with the use of different positive serum dilutions.

The aim of our study is to investigate the involvement of IL23R, JAK2, and STAT3 polymorphisms in inflammatory bowel diseases in a Turkish population.

A case with Emanuel syndrome: extra derivative 22 chromosome inherited from the mother.

Emanuel syndrome (ES) is a rare chromosomal disorder that is characterized by multiple congenital anomalies and developmental disabilities. Affected children are usually identified in the newborn period as the offspring of balanced (11;22) translocation carriers. Carriers of this balanced translocation usually have no clinical symptoms and are often identified after the birth of offspring with an unbalanced form of the translocation, the supernumerary der(22) t(11;22) syndrome.

KRAS Mutation in Small Cell Lung Carcinoma and Extrapulmonary Small Cell Cancer.

Background: Lung cancer is one of the most lethal cancers. It is mainly classified into 2 groups: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Extrapulmonary small cell carcinomas (EPSCC) are very rare.

Impact of active smoking on survival of patients with metastatic lung adenocarcinoma harboring an epidermal growth factor receptor (EGFR) mutation.

Lung cancer in smokers and non-smokers demonstrates distinct genetic profiles, and cigarette smoking affects epidermal growth factor receptor (EGFR) function and causes secondary EGFR tyrosine kinase resistance. We evaluated the effect of active smoking in patients with metastatic lung adenocarcinoma. A total of 132 metastatic lung adenocarcinoma patients, diagnosed between 2008 and 2013, with known EGFR mutation status, were evaluated retrospectively.

The investigation of killer cell immunoglobulin-like receptor genotyping in patients with systemic lupus erytematosus and systemic sclerosis.

Systemic sclerosis (SSc) is another autoimmune disease that causes fibrosis. We will aim to analyse the role of killer cell immunoglobulin-like receptor (KIR) genotypes and their existence with the respective HLA ligands in patients with SLE and SSc.
