TAP1 and TAP2 genes encode heterodimeric molecule involved in endogenous antigen processing. The present study was undertaken to find out the possible association between TAP1 and TAP2 polymorphisms and risk of pulmonary tuberculosis (PTB) in a sample of Iranian population. Polymorphisms of TAP1 (rs1057141, rs1135216) and TAP2 (rs2228396, rs241447, rs67511411, rs141555015) were determined in 17...

Qinchuan is a red or yellow draft and beef breed in China. In order to identify a predictor of carcass traits on the basis of associations between carcass traits and gene polymorphism, variation in the bovine chemerin gene was investigated using PCR-single-strand conformational polymorphism and DNA sequencing. An SNP of A868G located in exon 2 of the Bos taurus chemerin gene was detected ...

OBJECTIVE To assess the association between coronary heart disease (CHD) and vitamin D receptor (VDR) gene polymorphisms in Han Chinese adults. METHODS A total of 215 CHD patients and 67 controls were recruited. In both groups, the VDR gene single nucleotide polymorphisms (SNP) of Tru9I (rs757343), ApaI (rs7975232), TaqI (rs731236) and FokI (rs2228570) were detected, and the frequencies of VD...

We studied the association between aldehyde dehydrogenase 2 (ALDH2) polymorphism and coronary artery disease (CAD) and clarified the mechanisms underlying this association. We searched the ISI, Medline (Ovid), PubMed, CNKI, Wanfang, and Weipu Databases. Statistical analysis was performed using Revman 5.0 and Stata12.0 softwares. A total of 3305 cases and 5016 controls in 12 case-control studies...

The interleukin-6 (IL-6)/JAK/STAT3 signaling pathway plays a central role in inflammation-mediated cancers, including gastric cancer (GCa). We evaluated associations between 10 potentially functional single nucleotide polymorphisms (SNPs) of four essential genes in the pathway and GCa risk in a study of 1,125 GCa cases and 1,221 cancer-free controls. We found that a significant higher GCa risk ...

BACKGROUND Single nucleotide polymorphisms (SNPs) occurred in pre-microRNAs or targets of microRNAs (miRs) may contribute to cancer risks. Since 2007, many studies have investigated the association between common SNPs located on hsa-miR-499 (rs3746444) and cancer risks; however, the results were inconclusive. METHODOLOGY/PRINCIPAL FINDINGS We conducted a meta-analysis of 12 studies that inclu...

objective: cytochrome p450 is one of the major drug metabolizing enzyme families and its role in metabolism of cancer drugs cannot be less emphasized. the association between single nucleotide polymorphisms (snps) in cyp1a1 and pathogenesis of chronic myeloid leukemia (cml) has been investigated in several studies, but the results observed vary based on varied risk factors. the objective of thi...
