Associations between polymorphisms in the IL-4 and IL-4 receptor genes and urinary carcinomas: a meta-analysis.

ABSTRACT: To evaluate the association between polymorphisms of interleukin-4 (IL-4) and IL-4 receptor (IL-4R) genes and risk of renal cell cancer (RCC), bladder cancer (BC), and prostate cancer (PC) based on meta-analysis. PubMed, Web of Science and SpecilalSCI(TM) were searched for studies published up to May 2014 that reported the association between IL-4 or IL-4R and RCC, BC or PC risk. Odds ratio (OR)/Hazard ratio (HR) and 95% confidence interval (CI) were analyzed to evaluate the association. Meta-analysis showed that the IL-4R polymorphism rs1805010 was associated with increased RCC risk (CC/CT vs. TT: OR=1.266, 95% CI 1.09-1.472, P=0.002). The IL-4 haplotypes, IL4-589T and IL4-33T, were associated with higher survival rate of the patients comparted with the haplotype IL-4-589C-33C (P<0.05). The IL-4 polymorphism rs2243250 was associated with an increased risk of developing multiple BCs (OR=2.52, P=0.033). The IL-4 polymorphisms rs2243228, rs2243250, and rs22272480 were significantly associated with PC risk (rs2243228 CC vs.

Three polymorphisms (rs2070874, rs1805015, and rs1801275) were not associated with RCC, BC, and PC. The IL-4R polymorphism rs1805015 might be associated with RCC risk. IL-4 rs2243250 carriers had increased risk of developing multiple BCs. IL-4 polymorphisms rs2243228, rs2243250, rs2227284, and rs2070874 were associated with PC risk or mortality.

Project description:BackgroundMany epidemiological studies have suggested an association between estrogen receptor-beta (ER-β) polymorphisms with endometriosis risk. However, the results of these studies have been inconsistent. In the present study, we performed a meta-analysis to clarify the associations between the ER-β rs4986938 and rs1256049 polymorphisms and endometriosis risk.MethodsEligible publications were retrieved from the PubMed, ISI Web of Science, and several Chinese language databases. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using a random or fixed effect model.ResultsA total of eight studies (1100 cases/1485 controls) for the rs4986938 polymorphism and four studies (353 cases/450 controls) for the rs1256049 polymorphism were included in this meta-analysis. Regarding the rs4986938 polymorphism, no obvious associations were found for all genetic models when all studies were pooled into the meta-analysis. In the subgroup analyses by ethnicity, study sample size, endometriosis-associated infertility, and stage of endometriosis, a significantly increased risk was observed among mixed populations (dominant model, OR=2.03, 95% CI=1.56-2.64) and among cases with endometriosis-associated infertility (dominant model, OR=1.83, 95% CI=1.26-2.67). Regarding the rs1256049 polymorphism, no obvious associations were found for all genetic models in the overall population. Subgroup analyses by ethnicity and study sample size revealed that only one study of a mixed population with small sample size showed an increased risk of endometriosis. No publication bias was found in the present study.ConclusionsThe results of this meta-analysis suggest that the ER-β rs4986938 and rs1256049 polymorphisms may not be associated with endometriosis risk, while the observed increased risk of endometriosis-associated infertility may be due to bias by the inclusion of small-scale studies.Virtual slidesThe virtual slide(s) for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/13000_2014_184.

Project description:Objective: It is suggested that estrogen receptors (ERs) might be associated with the disproportionate vulnerability of women to depressive episodes. Several variants in ER-alpha (ERα) and ER-beta (ERβ) have been linked to depression, but the results were not consistent. Hence, we conducted a meta-analysis to evaluate the association between ERα/ERβ and depression in a cohort of women. Methods: A comprehensive literature search was performed in public databases. The genetic association between polymorphisms in Erα/ERβ and depression risk in a cohort of women was evaluated by odds ratios (ORs) and 95% confidence intervals (CIs). Cochran's Q test and the I2 index were used to evaluate heterogeneity. Results: In total, 10 studies and 4 SNPs (rs2234693, rs9340799, rs4986938, rs1256049) were included in our meta-analysis. rs2234693 genotype was significantly associated with the risk of depression in women by dominant model (CC + CT vs TT, OR = 1.30, 95% CI: 1.09-1.55, p = 0.0031), recessive model (CC vs CT + TT, OR = 1.64, 95% CI: 1.00-2.67, p = 0.0478), additive model (CC vs TT, OR = 1.93, 95% CI: 1.12-3.35, p = 0.0189) and allelic model (C vs T, OR = 1.24, 95% CI: 1.10-1.39, p = 0.0003). For rs9340799, the frequencies of risk genotypes according to the dominant (GG + GA vs AA, OR = 1.47, 95% CI = 1.10-1.98, p = 0.0096, I2 = 0%, p = 0.43) and allelic (G vs A, OR = 1.33, 95% CI: 1.04-1.69, p = 0.0236, I2 = 0%, p = 0.39) models were significantly lower in women with depression than in controls within the Asian subgroup. For rs1256049, risk genotypes were significantly more frequent in depressed subjects than in controls under the dominant model (AA+ GA vs GG, OR = 1.62, 95% CI: 1.19-2.21, p = 0.0024) and the allelic model (A vs G, OR = 1.35, 95% CI: 1.07-1.72, p = 0.012) after sensitivity analysis by omitting one study which induce the heterogeneity. Conclusions: The current meta-analysis is the first and most comprehensive investigation of the association between ERs and depression in women, and the findings support the concept that ERs participate in the etiology of sex heterogeneity in depression.

Project description:Cancer incidence is dramatically increasing worldwide, therefore improved prediction and therapeutic methods are needed. Single nucleotide polymorphisms in cytokine genes may contribute to carcinogenesis. Interleukin (IL)‑4 gene polymorphisms have been intensively studied with regard to their associations with cancer. However, the results of these previous studies remain inconclusive. The present study, therefore, aimed to conduct a meta‑analysis of previously published studies in order to clarify the association of IL‑4 with cancer risk. Eligible published articles were searched in Medline, PubMed, Embase and China National Knowledge Infrastructure databases up to March 2016. Odds ratios and 95% confidence intervals were used to identify potential associations between IL‑4 genetic polymorphisms and the risk of cancer. A meta‑analysis was then performed on 10,873 patients and 14,328 controls for IL‑4 rs2243250 polymorphism, 3,970 patients and 5,686 controls for IL‑4 rs2070874 polymorphism, and 1,896 patients and 2,526 controls for IL‑4 rs79071878 polymorphism. A significant association with cancer risk was observed for rs2243250 and rs79071878 polymorphisms. In the subgroup analysis by cancer type, rs2243250 polymorphism was demonstrated to be associated with an increased risk of gastric cancer and breast cancer, rs2070874 polymorphism was correlated with leukemia and oral carcinoma, and rs79071878 polymorphism was relevant to bladder carcinoma risk. In the subgroup analysis by ethnicity, IL‑4 rs2243250 polymorphism was demonstrated to be associated with cancer risk in both Caucasian and Asian populations, rs2070874 was associated with cancer risk in Asian populations, while rs79071878 polymorphism was associated with cancer risk in Caucasian populations. In conclusion, the present results suggested that the IL‑4 rs2243250 and rs79071878 polymorphisms were associated with cancer susceptibility. Further subgroup analyses revealed that the effects of IL‑4 gene polymorphisms on cancer risk may vary by cancer type and by ethnicity.
