We conducted a case-control study to assess the LIG4 and XRCC4 genes polymorphisms and development of glioma. A case-control study including 162 glioma cases and 324 controls was conducted in a Chinese population. Genotypes of rs10131 and rs1805388 in LIG4 and rs2075685 and rs1805377 in XRCC4 were conducted by polymerase chain reaction restriction fragment(More)
This meta-analysis was undertaken to identify the relationships between genetic polymorphisms in the LDLR gene and the risk of cerebral infarction. The Web of Science (1945–2013), the Cochrane Library Database (Issue 12, 2013), PubMed (1966–2013), EMBASE (1980–2013), CINAHL (1982–2013) and the Chinese Biomedical Database (CBM) (1982–2013) were searched for(More)
Studies on the relationship of HAP1 polymorphisms (−141 T > G; 1349 T > G) and lung cancer risk to date indicated controversial results. This study was devised to clarify whether the polymorphisms predispose to lung cancer. We searched Embase and PubMed up to March 2014 to identify relevant studies. Data from the eligible studies were independently(More)
, has been retracted by the authors request. The authors have recently obtained new results conflicting with those presented in the pubb lished article. Careful analysis showed that some published results were obtained using inappropriate methods and wrong statistical analysis. The authors apologize and ask readers to ignore the results published in this(More)
Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung. Leptin is a pleiotropic hormone with antiapoptotic and proliferative roles involved in several systems. However, there is no known antiapoptotic mechanism of leptin in non-small cell lung cancer (NSCLC). So, we investigated the antiapoptotic mechanism of leptin in(More)
