Project description:BACKGROUND: Single nucleotide polymorphisms (SNPs) in microRNA-coding genes may participate in the process of carcinogenesis by altering the expression of tumor-related microRNAs. It has been suggested that two common SNPs rs2910164 in miR-146a and rs11614913 in miR-196a2 are associated with susceptibility to hepatocellular carcinoma (HCC). However, published results are inconsistent and inconclusive. In the present study, we performed a meta-analysis to systematically summarize the possible association between the two SNPs and the risk for HCC. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a search of case-control studies on the associations of SNPs rs2910164 and/or rs11614913 with susceptibility to HCC in PubMed, EMBASE, ISI Web of Science, Cochrane Central Register of Controlled Trials, ScienceDirect, Wiley Online Library and Chinese National Knowledge Infrastructure databases. Data from eligible studies were extracted for meta-analysis. HCC risk associated with the two polymorphisms was estimated by pooled odds ratios (ORs) and 95% confidence intervals (95% CIs). 5 studies on rs2910164 and 4 studies on rs11614913 were included in our meta-analysis. Our results showed that neither allele frequency nor genotype distribution of the two polymorphisms was associated with risk for HCC in all genetic models. Similarly, subgroup analysis in Chinese population showed no association between the two SNPs and the susceptibility to HCC. CONCLUSIONS/SIGNIFICANCE: This meta-analysis suggests that two common SNPs rs2910164 and rs11614913 are not associated with the risk of HCC. Well-designed studies with larger sample size and more ethnic groups are required to further validate the results.

Project description:To assess the association between Interleukin-10 (IL-10) gene IL-10-1082 (G/A), IL-10-592(C/A), IL-10-819 (T/C) polymorphisms and hepatocellular carcinoma (HCC) susceptibility.Two investigators independently searched the Medline, Embase, China National Knowledge Infrastructure, and Chinese Biomedicine Database. Summary odds ratios (ORs) and 95% confidence intervals (95% CIs) for IL-10 polymorphisms and HCC were calculated in a ?xed-effects model (the Mantel-Haenszel method) and a random-effects model (the DerSimonian and Laird method) when appropriate.This meta-analysis included seven eligible studies, which included 1012 HCC cases and 2308 controls. Overall, IL-10-1082 G/A polymorphism was not associated with the risk of HCC (AA vs AG + GG, OR = 1.11, 95% CI = 0.90-1.37). When stratifying for ethnicity, the results were similar (Asian, OR = 1.12, 95% CI = 0.87-1.44; non-Asian, OR = 1.10, 95% CI = 0.75-1.60). In the overall analysis, the IL-10 polymorphism at position -592 (C/A) was identi?ed as a genetic risk factor for HCC among Asians; patients carrying the IL-10-592*C allele had an increased risk of HCC (OR = 1.29, 95% CI = 1.12-1.49). No association was observed between the IL-10-819 T/C polymorphism and HCC susceptibility (TT vs TC + CC, OR = 1.02, 95% CI = 0.79-1.32).This meta-analysis suggests that IL-10-592 A/C polymorphism may be associated with HCC among Asians. IL-10-1082 G/A and IL-10-819 T/C polymorphisms were not detected to be related to the risk for HCC.

Project description:BackgroundRecent studies suggested that two common polymorphisms, miR-146a G>C and miR-196a2 C>T, may be associated with individual susceptibility to hepatocellular carcinoma (HCC). However, the results remain conflicting rather than conclusive. Object. The aim of this study was to assess the association between miR-146a G>C and miR-196a2 C>T polymorphisms and the risk of HCC.MethodsA meta-analysis of 17 studies (10938 cases and 11967 controls) was performed. Odds ratios and 95% confidence intervals were used to evaluate the strength of the association.ResultsFor miR-146a G>C, the variant genotypes were associated with a decreased risk of HCC (CC versus GG: OR = 0.780 and 95% CI 0.700-0.869; GC/CC versus GG: OR = 0.865 and 95% CI 0.787-0.952; CC versus GC/GG: OR = 0.835 and 95% CI 0.774-0.901). For miR-196a2 C>T, significant association was also observed (TT versus CC: OR = 0.783, 95% CI: 0.649-0.943, and P = 0.010; CT versus CC: OR = 0.831, 95% CI 0.714-0.967, and P = 0.017; CT/TT versus CC: OR = 0.817, 95% CI 0.703-0.949, and P = 0.008).ConclusionThe two common polymorphisms miR-146a G>C and miR-196a2 C>T were associated with decreased HCC susceptibility, especially in Asian population.

Project description:Aim of the studyWe reported the association between interleukin 6 polymorphisms (rs1800796, rs1800795, rs2069837, rs17147230, and rs1800797) and hepatocellular carcinoma (HCC) susceptibility in a meta-analysis.Material and methodsThe studies were retrieved by searching the search terms in Scopus, PubMed, Web of Science, and Cochrane Library databases until June 2020. The analyses were done by RevMan 5.3 software using odds ratios (ORs) and 95% confidence intervals (CIs) and the analysis of publication bias and sensitivity analyses were performed by CMA 2.0 software.ResultsSearching through the databases, 316 records were retrieved and finally 13 studies were analyzed in the present meta-analysis. For the rs1800797 polymorphism, there was an elevated risk of AA genotype (OR = 2.68, p = 0.03) in HCC patients compared to healthy controls. Also, there was an elevated risk of AA (OR = 3.06, p = 0.04) and GA (OR = 2.61, p = 0.005) genotypes in HCC patients compared to liver cirrhosis patients. For rs2069837 polymorphism, there was an elevated risk of GG genotype (OR = 2.25, p = 0.01) in HCC patients compared to healthy controls. For rs17147230, T allele (OR = 1.31, p = 0.03) and TT genotype (OR = 1.83, p = 0.02) had elevated risks in HCC patients compared to healthy controls.ConclusionsThe present meta-analysis confirmed that there was an elevated risk of the AA and GA genotypes of rs1800797 polymorphism and the GG genotype of rs2069837, and the T allele and TT genotype of rs17147230 in HCC.

Project description:BackgroundHepatocellular carcinoma (HCC) is an intractable public health threat worldwide, representing the second leading cause of cancer-related mortality, with limited early detection and therapeutic options. Recent findings have revealed that the susceptibility of HCC is closely related to microRNA (miRNA). We performed this systematic review with a network meta-analysis to investigated four single nucleotide polymorphisms (SNPs) that most regularly reported in miRNAs, exploring their involvement in HCC susceptibility and interaction with hepatitis B virus (HBV).MethodsDatabases were reviewed for related studies published up to May 2019 to identify all studies that compared genotypes of miR-146a rs2910164, miR-149 rs2292832, miR-196a2 rs11614913, and miR-499 rs3746444 with no language and date restrictions. A pairwise meta-analysis was performed to estimate pooled odds ratios and 95% confidence intervals incorporating heterogeneity to assess the relationship between four miRNA polymorphisms and HCC. To further clarify the effect of polymorphisms on HCC, a Bayesian network meta-analysis was conducted to combine the effective sizes of direct and indirect comparisons. Calculations were performed by R version 3.6.1 and STATA 14.0. All steps were performed according to PRISMA guidelines.ResultsA total of 20 studies were enrolled in this network meta-analysis, providing 5,337 hepatocellular carcinoma cases and 6,585 controls. All included studies had an acceptable quality. Pairwise meta-analysis demonstrated that miR-196a2 rs11614913 was significantly associated with the susceptibility of HCC, while the other three SNPs were not found to have a significant association. In the analysis of HCC patients under different HBV infection status, only miR-196a2 revealed correlation of threefold risk. The network results showed no significant difference in the distribution of genotype frequencies except for miR-196a2, which appeared to have the highest superiority index when comparing and ranking four SNPs.ConclusionMiR-196a2 rs11614913 was significantly associated with the susceptibility of HCC, especially for HBV- related HCC, and that individuals with TC/CC were more susceptible. No significant association was found in the other three miRNA genes. MiR-196a2 could serve as the best predictor of susceptibility in HCC.

Project description:BackgroundThis study aimed to determine whether CD44 polymorphisms were correlated with hepatocellular carcinoma (HCC) and to reveal a new potential target for early prediction, prevention, and diagnosis of HCC.MethodThis study involved 96 cases with chronic hepatitis B (CHB), 96 cases with hepatitis B virus-related liver cirrhosis (LC), 204 cases with HCC related to the hepatitis B virus, and 210 healthy controls. The genotype of rs8193 was determined using the restriction fragment length polymorphism method, while the genotypes of rs10836347 and rs13347 were determined by direct sequencing.ResultsThe results showed that patients with the CD44 rs13347 TT and T allele polymorphisms exhibited higher risks of LC than those carrying the CC genotype and C allele. The CD44 rs13347 CT and TT genotypes and T allele were significantly associated with an increased risk of HCC after adjusting for gender, age, smoking, and alcohol consumption (for CT: odds ratio [OR] = 1.626, 95% confidence interval [CI] = 1.057-2.500, P = .027; for TT: OR = 1.965, 95% CI = 1.043-3.702, P = .037; and for T: OR = 1.461, 95% CI = 1.091-1.956, P = .011). In the rs13347 site of the female population, the CT and TT genotypes were related to the high occurrence of HCC. In the population aged ≥50 years, carriers of the CD44 rs13347 CT and TT alleles were more susceptible to HCC compared with CC carriers. Those who consumed alcohol who carried the rs10836347 CT genotype exhibited a risk factor for HCC.ConclusionFor the CD44 rs13347 site, mutations in the T allele might be a risk factor for HCC.

Project description:IntroductionThe results of the earlier published studies on the association between KIF1B (rs17401966) polymorphism and hepatocellular carcinoma (HCC) risk are inconclusive. Hence, we performed this meta-analysis to evaluate the relationship between KIF1B (rs17401966) polymorphism and HCC risk.MethodsDatabases including PubMed, Web of Science and the Cochrane Library and bibliographies of relevant papers were screened to identify relevant studies published up to March 25, 2018. Pooled ORs and 95% CIs were calculated to evaluate the association. The subgroup analysis was conducted based on ethnicity, age, region and environment. A total of 19 studies from 11 eligible articles published from 2010 to 2016, with 8,741 cases and 10,812 controls, were included.ResultsThe pooled results indicated that the association between KIF1B (rs17401966) polymorphism and the decreased HCC risk was significant. Subgroup analysis stratified by ethnicity showed the same association in Chinese, but not in non-Chinese population. When stratified by age, both old and young patients showed a decrease in HCC risk. When stratified by region, we detected the same association in Chinese in southern China. Similarly when stratified by environment, we observed the same association in Chinese in inland areas; however, no statistically significant association was observed in those in coastal areas.ConclusionThis meta-analysis suggested that KIF1B (rs17401966) polymorphism could decrease HCC risk in Chinese and in overall population, but not in non-Chinese. This association remained significant in Chinese in southern China and inland areas, but not in those in northern and central China and coastal areas. Further large-scale multicenter studies are warranted to confirm these findings.

Project description:BackgroundAssociations between transforming growth factor (TGF)-β1 polymorphisms and hepatocellular carcinoma (HCC) risk remained controversial. Therefore, we performed this meta-analysis to investigate these associations.MethodsWe searched Pubmed, EMBASE, Chinese National Knowledge Infrastructure (CNKI), and Wanfang databases for studies before March 2013. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to calculate the strength of association.ResultsA total of 14 studies were included in this meta-analysis. TGF-β1 +869C/T polymorphism was significantly associated with HCC risk (OR=1.74, 95% CI: 1.22-2.47, p=0.002). In addition, a significant association between -509C/T polymorphism and HCC risk was observed (OR=1.40, 95% CI: 1.15-1.70, p=0.0007). Furthermore, significant associations between these polymorphisms and HCC risk were found in Asians and population-based studies.ConclusionsOur meta-analysis suggested that the TGF-β1 +869C/T and -509C/T polymorphisms may be risk factors for developing HCC.

Project description:TARGET:Our study was to investigate the effects of interleukin-6 (IL-6) polymorphisms (rs2069837 and rs17147230) on the risk for hepatocellular carcinoma (HCC). METHODS:A total of 226 HCC cases and 220 healthy controls were admitted into the study and genomic DNA was extracted from the peripheral blood. The genotyping was conducted by the method of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Odds ratio (OR) and 95% confidence interval (CI) were used to evaluate the relationship of IL-6 rs2069837 and rs17147230 polymorphisms with HCC susceptibility. RESULTS:The frequency of GG genotype of rs2069837 was higher in HCC patients, compared with controls (P < 0.05). Moreover, the results indicated that GG genotype was related with increased risk for HCC (OR = 2.303, 95% CI = 1.056-5.025). Similarly, the risk for G allele carriers was higher than that of A allele (OR = 1.392, 95% CI = 1.046-1.852). For rs17147230, TT genotype showed strong effect on HCC susceptibility (OR = 2.089, 95% CI = 1.135-3.845) and T allele appeared to be a risk factor for HCC (OR = 1.326, 95% CI = 1.010-1.740). Further analysis showed that G-T haplotype was associated with increased risk for HCC (OR = 3.125, 95% CI = 1.845-5.294, P = 0.000). CONCLUSION:IL-6 rs2069837 as well as rs17147230 were associated with HCC susceptibility. In addition, G-T haplotype also served as a genetic-susceptibility factor for HCC.

Project description:BackgroundThe association between methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms and hepatocellular carcinoma (HCC) risk was inconsistent and underpowered. To clarify the effects of MTHFR gene polymorphisms on the risk of HCC, a meta-analysis of all available studies relating C677T and/or A1298C polymorphisms of MTHFR gene to the risk of HCC was conducted.MethodsThe authors searched PubMed, EMBASE, Cochrane Library, Web of Science, and Chinese Biomedical Literature database (CBM) for the period up to July 2012. Data were extracted by two independent authors and pooled odds ratio (OR) with 95% confidence interval (CI) was calculated. Metaregression and subgroup analyses were performed to identify the source of heterogeneity.ResultsFinally, 12 studies with 2,351 cases and 4,091 controls were included for C677T polymorphism and 6 studies with 1,333 cases and 1,878 controls were included for A1298C polymorphism. With respect to A1298C polymorphism, significantly decreased HCC risk was found in the overall population (CC vs. AA: OR?=?0.660, 95%CI 0.460-0.946, P?=?0.024; recessive model: OR?=?0.667, 95%CI?=?0.470-0.948, P?=?0.024). In subgroup analyses, significantly decreased HCC risk was found in Asian population (CC vs. AA: OR?=?0.647, 95%CI?=?0.435-0.963; P?=?0.032) and population-based studies (CC vs. AA: OR?=?0.519, 95%CI?=?0.327-0.823; P?=?0.005). With respect to C677T polymorphism, no significant association with HCC risk was demonstrated in overall and stratified analyses.ConclusionsWe concluded that MTHFR A1298C polymorphism may play a protective role in the carcinogenesis of HCC. Further large and well-designed studies are needed to confirm this association.
