قدمه: سرطان کلورکتال (crc یا colorectal cancer) یکی از سرطان های شایع در جهان است. فعالیت بیش از حد ژن cyclind1 در پیشبرد این سرطان دیده شده است. پلی مورفیسم g870a در اگزون 4 این ژن، منجر به تولید یک رونوشت متناوب می شود که نیمه عمر طولانی تری دارد و ممکن است با رشد سلولی غیر قابل کنترل به توسعه ی سرطان کمک کند. مطالعه ی حاضر، به منظور بررسی فراوانی نسبی پلی مورفیسم g870a در ژن ccnd1 در افراد م...
سرطان پوست یکی از شایع ترین انواع سرطان ها در سراسر جهان می باشد که بیش از 50% از تمام سرطان ها را شامل می شود. سه نوع اصلی سرطان پوست وجود دارد. فراوان ترین فرم آن، کارسینومای سلول پایه می باشد (bcc)، کارسینومای سلول پوششی (scc) و ملانوما (cmm) انواع دیگر آن می باشند. پرتو فرابنفش خورشید که منجر به آسیب dna می شود، مهم ترین فاکتور خطر برای تمام انواع سرطان پوست است. ژن tp53 یکی از ژن های کلیدی...
Whether cyclin D1 (CCND1) gene variants increase susceptibility to head and neck cancer (HNC) is undetermined. Therefore, we performed the present meta-analysis to systematically assess any possible association between CCND1 variants (G870A and G1722C) and HNC risk. Seventeen studies for CCND1 G870A and three studies for CCND1 G1722C were included. Overall, CCND1 polymorphisms (G870A and G1722C...
Evidence implicates cyclin D1 (CCND1) G870A polymorphisms as risk factors for various cancers. An increasing number of investigations have been conducted on the association of CCND1 G870A polymorphisms with susceptibility to oral carcinoma, and have yielded inconclusive results. The aim of the present study was to derive a more precise estimation of the correlation. Meta-analyses examining the ...
BACKGROUND Cyclin D1 (CCND1) plays a key role in cell cycle regulation. It is a well-established human oncogene which is frequently amplified or overexpressed in cancers. The association between CCND1 G870A polymorphism and cancer risk has been widely assessed. However, a definitive conclusion between CCND1 G870A polymorphism and risk of nasopharyngeal carcinoma (NPC) remains elusive. METHODS...
BACKGROUND The Cyclin D1(CCND1) G870A polymorphism may be associated with breast cancer, but the evidence from individual studies is inconclusive. The aim of this study was to investigate the correlation between the CCND1 G870A polymorphism and breast cancer risk in a meta-analysis. MATERIALS AND METHODS We searched Pubmed and analysed 11 articles on 5,528 cases and 5,353 controls before Febr...
Published data on the association between cyclin D1 (CCND1) G870A polymorphism and gastric cancer (GC) risk are inconclusive. Thus, we conducted a meta-analysis to evaluate the relationship between CCND1 G870A polymorphism and GC risk. We searched PubMed, EMBASE, Web of science and the Cochrane Library up to June 12, 2015 for relevant studies. Odds ratios (ORs) and 95% confidence intervals (CIs...
CCND1 plays a key role in cell cycle progression and may cause methotrexate (MTX) resistance, as well as its cytotoxicity. CCND1 870A variant allele is associated with altered transcripts of this gene. We hypothesized that this polymorphism may contribute to the elimination rate and hepatotoxicity of MTX in childhood acute lymphoblastic leukemia (ALL). We genotyped the CCND1 G870A polymorphism ...
UNLABELLED In recent years, mounting evidence has indicated that the CCND1 G870A gene polymorphism, which impacts the mitotic cell cycle, may influence leukemia or non-Hodgkin lymphoma risk. Unfortunately, the previous results were inconsistent. Therefore, a meta-analysis was performed to obtain a more precise estimation of any association. We conducted a search in PubMed, Embase and CNKI cover...
OBJECTIVE To study G870A polymorphism in CCND1 gene and the risk of cervical cancer susceptibility in Caucasian population by meta-analysis. METHODS Search the correlative study of G870A polymorphism in CCND1 gene and cervical cancer susceptibility in PubMed and EMBASE database, and extract the reference data according to the including criteria. We used RevMan 5.2 software to merge the OR val...
