Meta-analysis demonstrates that the NAD(P)H: quinone oxidoreductase 1 (NQO1) gene 609 C>T polymorphism is associated with increased gastric cancer risk in Asians

Y. Zhang, Wang, Z. T., and Zhong, J., “Meta-analysis demonstrates that the NAD(P)H: quinone oxidoreductase 1 (NQO1) gene 609 C>T polymorphism is associated with increased gastric cancer risk in Asians”, vol. 11, pp. 2328-2337, 2012.

The association between the NAD(P)H: quinone oxidoreductase 1 (NQO1) gene C609T polymorphism and gastric cancer has been widely evaluated, yet with conflicting results. Data were available from seven study populations involving 2600 subjects. Overall, comparison of alleles 609T and 609C indicated a significantly increased risk (46%) for gastric cancer (95% confidence interval (95%CI) for odds ratio (OR) = 1.20-1.79) in individuals with the T allele. The tendency was increased in the homozygous comparison (609TT versus 609CC), with an OR = 2.04 (95%CI = 1.37-3.05).

Association between HLA-Cw*0602 polymorphism and psoriasis risk: a meta-analysis

D. Wu, Wu, Y., Liu, J. L., Wang, B., and Zhang, X. D., “Association between HLA-Cw*0602 polymorphism and psoriasis risk: a meta-analysis”, vol. 10, pp. 3109-3120, 2011.

Numerous studies have evaluated the association between human leukocyte antigen (HLA) Cw*0602 polymorphism and psoriasis risk. However, the results have been inconsistent. We made a meta-analysis of the association between HLA-Cw*0602 polymorphism and psoriasis risk. Eighteen studies were retrieved, reporting a total of 3419 psoriasis patients and 3297 healthy controls. The associations between HLA-Cw*0602 polymorphism and psoriasis risk were estimated by pooled odds ratio (OR) and 95% confidence interval (95%CI).

Lack of an association between -308G>A polymorphism of the TNF-α gene and liver cirrhosis risk based on a meta-analysis

D. Chen, Liu, J. L., Liu, Y., Zhu, J., and Wang, S. W., “Lack of an association between -308G>A polymorphism of the TNF-α gene and liver cirrhosis risk based on a meta-analysis”, vol. 10, pp. 2765-2774, 2011.

TNF-α is a potential proinflammatory cytokine that plays an important role in the pathogenesis of liver cirrhosis. We investigated a possible association between TNF-α -308G>A polymorphism and liver cirrhosis risk by conducting a meta-analysis. Publications addressing the association between TNF-α -308G>A and liver cirrhosis risk were selected from the Pubmed and Embase databases. Data were extracted from the studies by two independent reviewers; odds ratio (OR) with a 95% confidence interval (CI) was calculated from these data.

Association of -619C/T polymorphism in CDSN gene and psoriasis risk: a meta-analysis

Y. Wu, Wang, B., Liu, J. L., Gao, X. H., Chen, H. D., and Li, Y. H., “Association of -619C/T polymorphism in CDSN gene and psoriasis risk: a meta-analysis”, vol. 10, pp. 3632-3640, 2011.

Previous studies investigating the association between corneodesmosin (CDSN) polymorphisms and psoriasis risk have provided inconsistent results. The aim of our study was to clarify the effects of CDSN -619C/T polymorphism on psoriasis risk by conducting a meta-analysis. We conducted searches of the published literature in Pubmed and Embase databases up to October 2010. Six studies with a total of 842 psoriasis cases and 981 healthy controls were retrieved. Statistical analysis was performed with the programs Review Manager (version 5.0.24) and Stata (version 9.2).
