Bladder cancer; CCR2-V64I; Chemokines; MCP-1 A-2518G; Polymorphism

Chemokines are potent proinflammatory cytokines that are implicated in numerous inflammatory diseases. Proinflammatory gene polymorphisms lead to variations in the production and concentration of inflammatory proteins. We investigated a possible association between polymorphisms in chemokine and chemokine receptor genes (MCP-1 A-2518G and CCR2-V64I) and bladder cancer risk. Genotypes were ... more

Bladder cancer; KEGG pathway; T1-T2; Ta-T1; Tumor grades

Bladder cancer is a highly heterogeneous neoplasm. We examined the gene expression profile in 3 bladder cancer stages (Ta, T1, T2) using expression microarray analysis of 40 bladder tumors. Differentially expressed genes were found by the t-test, with <0.005 as the significance threshold. KEGG pathway-enrichment analysis was used to study the signaling pathways of the genes. ... more

Apoptosis; Bladder cancer; Gene expression; RT-PCR

We examined the expression of anti-apoptotic genes (XIAP and Bcl-2) and apoptotic genes (cytochrome c, caspase-9, Apaf-1) in tissue samples of patients with superficial bladder cancer. Thirty-two bladder cancer tissue samples (8 papillary urothelial neoplasm of low malignant potential, 10 low-grade, and 14 high-grade) and 8 normal bladder ... more

Bladder cancer; Genetic susceptibility; hOGG1; Meta-analysis; Polymorphism

The functional polymorphism Ser326Cys (rs1052133) in the human 8-oxoguanine DNA glycosylase (hOGG1) gene has been implicated in bladder cancer risk. However, reports of this association between the Ser326Cys polymorphism and bladder cancer risk are conflicting. In order to help clarify this relationship, we made a meta-analysis of seven case-control studies, summing 2521 cases ... more

Bladder cancer; Gene polymorphism; Meta-analysis; XRCC1 Arg399Gln

We examined whether the X-ray repair cross-complementing group 1 (XRCC1) Arg399Gln polymorphism is a risk factor for bladder cancer by conducting a meta-analysis. We searched the Pubmed and Embase databases for study retrieval. This meta-analysis examined 16 case-control studies, including 892 prostate cancer cases and 1020 healthy controls. Meta-analysis results based on these studies ... more

Bladder cancer; Meta-analysis; PSCA; rs2294008 (C>T) polymorphism

Several published articles have evaluated the association between the prostate stem cell antigen (PSCA) rs2294008 (C>T) polymorphism and bladder cancer risk, but the results remain inconclusive. In order to derive a more precise estimation of the association, we performed a meta-analysis of four case-control studies that included 9617 cases and 16,323 controls. Odds ratios (ORs) and 95 ... more

Bladder cancer; Control mechanism; Genes; Module network

Bladder cancer is a common cancer worldwide and its incidence continues to increase. There are approximately 261,000 cases of bladder cancer resulting in 115,000 deaths annually. This study aimed to integrate bladder cancer genome copy number variation information and bladder cancer gene transcription level expression data to construct a causal-target module network of the range of ... more

Bladder cancer; FGFR3; Grade; Prognosis; Staging

Mutations in the fibroblast growth factor receptor-3 (FGFR3) gene are frequently found in bladder cancer, but their prognostic value remains controversial. To globally summarize the association between FGFR3 mutations and the grade and stage of bladder cancer, and to analyze the predictive role of FGFR3 mutations with respect to survival, eligible studies were ... more

B7-H1 expression; Bladder cancer; Meta-analysis

B7 homolog 1 (B7-H1), which is also known as programmed death-L1, is an important member of the B7/CD28 costimulatory factor superfamily, which are emerging as important mediators of various host immune responses. B7-H1 is differentially expressed in various cell subsets and to different extents in human and murine cells. Human B7-H1 is constitutively expressed at low levels in dendritic ... more

Biomarker; Gene polymorphism; Genetics; Non-small cell lung cancer; Survivin

Lung cancer is the most common cancer worldwide. Survivin is one of the first reported inhibitors of apoptosis proteins, which is an important family of proteins that regulate apoptosis. The survivin gene is located on human chromosome 17q25, which is composed of 142 amino acids. A common polymorphism of the survivin gene promoter -31G/C has been shown to influence cancer risk. This ... more
