The polymorphisms in codon 72 of the tumor suppressor protein p53 (P53) gene and codon 655 of the human epidermal growth factor receptor 2 (HER2) gene have been suggested to play roles in most cancers. The purpose of this study was to investigate the association between common variants of HER-2 and P53 genes with breast cancer risk. Blood samples collected(More)
OBJECTIVE To investigate MEFV mutations among patients with familial Mediterranean fever (FMF), their relatives, and healthy controls in the Black Sea region of Turkey; to compare 3 different MEFV mutation analysis methods; to evaluate the role of MEFV mutations in the diagnosis of FMF; and to investigate the role of M694V in the development of amyloidosis.(More)
BACKGROUND Matrix metalloproteinases (MMPs) are related to tissue destruction and remodeling events in periodontal diseases. A single nucleotide polymorphism in the promoter region of human MMP-9 gene is associated with the risk of some inflammatory diseases. Therefore, the aim of this study was to investigate the association between MMP-9 promoter(More)
Prostate cancer is the most common cancer among men in many countries. Although the etiology of prostate cancer largely is unknown, both genetic and environmental factors may be involved. Advanced age, androgen metabolism, and heredity-race have been reported to be possible risk factors. On the other hand, several studies indicate that genetic polymorphisms(More)
BACKGROUND & OBJECTIVE Genetic polymorphisms in the vitamin D receptor (VDR) gene are related to bone mineral density, bone turnover, and diseases with bone loss. Alveolar bone loss is a key feature in periodontitis. The aim of this study was to determine whether severe generalized chronic periodontitis (CP) in a Turkish population was associated with(More)
BACKGROUND Interleukin-10 (IL-10), an anti-inflammatory cytokine, plays a role in periodontal disease by inhibiting synthesis of proinflammatory cytokines and stimulating protective antibody production. Genetic polymorphisms in the IL-10 gene might be useful as a marker to diagnose susceptibility to periodontitis. Therefore, the aim of this study was to(More)
High levels of SOX4 gene expression have been reported in a variety of human cancers. The protein may function in the apoptosis pathway, leading to cell death as well as to tumorigenesis. The aim of this study was to investigate the levels of SOX4 expression in bladder cancer. Urinary bladder tumor samples were obtained from 57 bladder cancer and 13 normal(More)
We investigated the association of prostate cancer (PCa) and benign prostatic hyperplasia (BPH) with genetic polymorphisms in prostate-specific antigen (PSA) (-158 G/A) and 17-hydroxylase (CYP17) (-34 T/C) genes in a Turkish population. In this study, we investigated the distribution of these polymorphisms in 148 PCa patients, 136 BPH patients, and 102(More)
OBJECTIVE The aim of the present study was to investigate the prevalence of MEFV gene mutations in patients with ankylosing spondylitis (AS) and to assess the clinical significance of the MEFV gene mutations in AS. METHODS Eighty AS patients and 85 healthy controls were examined for 12 common MEFV mutations via strip-assay technique. Bath ankylosing(More)
The 46,XX testicular disorder of sex development (46,XX testicular DSD) is a rare phenotype associated with disorder of the sex chromosomes. We describe the clinical, molecular, and cytogenetic findings of a 16- and a 30-year-old male patient with sex-determining region Y (SRY)-positive 46,XX testicular DSD. Chromosomal analysis revealed 46,XX karyotype.(More)
