Increased Risk

Single nucleotide polymorphisms (SNPs) in microRNA may affect its expression and regulation of target genes, which may consequently alter individual susceptibility to cancer. In this study we aimed to investigate associations betweenmiR-122polymorphisms and hepatocellular carcinoma (HCC) in a southern Chinese population. Three selected SNPs inmiR-122(rs9966765, rs1135519, and rs17669) were genotyped in 1050 HCC patients and 1079 cancer-free controls using Sequenom MassARRAY platform and the associations of the three SNPs and HCC risk were evaluated. We found that individuals with the rs1135519 CC genotypes had a significant increased risk of HCC than those with TT genotypes (adjusted OR=2.71, 95% CI=1.15-6.36, andP=0.022), while the rs9966765 CC genotypes showed a borderline significant association with increased risk of HCC when compared with the GG genotypes (adjusted OR=2.38, 95% CI=0.99-5.75, andP=0.052). There was also a significant increased risk of HCC when combining risk genotypes of these loci, i.e., rs1135519 CC and rs9966765 CC. Compared with the low-risk group (0 risk genotype), the high risk group (1-2 risk genotypes) had significantly increased risk of HCC (OR=1.61, 95% CI=1.05-2.44, andP=0.028). Further genotype-expression analysis revealed that cases carrying the CC genotype of rs1135519 had lower levels ofmiR-122expression than those with the TT genotype. Our results suggest that SNP of rs1135519 modulatesmiR-122expression and contributes to the genetic susceptibility of HCC, either independently or together with rs9966765 inmiR-122.Further well-designed studies with lager sample sizes are needed to confirm our findings.

The Relationship

The interleukin- (IL-) 33/ST2 axis plays a pivotal role in tumorigenesis through influencing cancer stemness and other mechanisms. CD44 is one of the critical markers of hepatocellular carcinoma (HCC) among the cancer stem cells (CSCs). There is still a lack of CD44 gene single-nucleotide polymorphisms (SNPs) combined with IL-33/ST2 pathway single-nucleotide polymorphisms in HCC susceptibility analysis literature, although CD44 and IL-33/ST2 have been reported separately in human cancers. This study is aimed at investigating the relationship between CD44, IL-33, and ST2 SNPs and HCC susceptibility and clinicopathological features. We analyzed 565 HCC patients and 561 healthy controls in the Chinese population. The genes for CD44rs187115A>G, IL-33 rs1929992A>G, and ST2 rs3821204G>C were typed using the SNaPshot method. We found that the distribution frequencies of CD44 and ST2 alleles and genotypes in both the HCC case group and the control group were statistically significant ( p < 0.05 ). The results showed that individuals carrying at least one G allele of the CD44 rs187115 gene were at a higher risk than the AA genotype carriers ( p = 0.007 , odds   ratio   OR = 1.429 , 95% confidence interval (CI): 1.102–1.854). Similarly, individuals with at least one C allele of ST2 rs3821204 had a higher risk of HCC than those with GG genes ( p ≤ 0.001 , OR = 1.647 , 95% CI: 1.296-2.093). Combining the haplotype analysis of the 3 loci suggested that CD44 rs187115, IL-33 rs1929992, and ST2 rs3821204 are associated with the risk of HCC and could potentially serve as useful genetic markers for HCC in some populations of China.

BackgroundThe long noncoding RNA HOX transcript antisense RNA (HOTAIR) is highly expressed in breast cancer (BC) tissues and is associated with the recurrence and metastasis of BC. Until now, the results of studies on associations between several functional single nucleotide polymorphisms(SNPs) (rs920778, rs1899663, and rs4759314) in HOTAIR with BC susceptibility carried out in different regions of China are still inconsistent. There is no study on correlation between HOTAIR SNPs and prognosis of Chinese population. Therefore, we investigated the relationship between HOTAIR SNPs and susceptibility to and prognosis of BC.MethodWe conducted a population-based case-control study involving 828 BC cases and 905 healthy controls. Peripheral blood DNA was used for genotyping. The association between HOTAIR genotypes and BC risk were estimated by odds ratios (ORs) computed using the binary logistic regression model. The relationships between HOTAIR SNPs and clinicopathological features were tested by Pearson’s chi-square test or Fisher’s exact test. Survival was analyzed using the Kaplan-Meier method.ResultsThe functional rs920778 genetic variant increased BC risk in the codominant model. Individuals with the rs920778 GG genotype had an OR of 2.426 (95% confidence interval [CI] = 1.491–3.947, P &lt; 0.001) for developing BC compared to individuals with the AA genotype. Individuals with the AG genotype had an OR of 1.296 (95% CI = 1.040–1.614, P = 0.021) for developing BC compared to individuals with the AA genotype. Individuals with the rs4759314 GA genotype had a lower BC risk than individuals with the rs4759314 AA/GG genotype (OR = 0.566, 95% CI = 0.398–0.803, P = 0.001). The rs1899663 genotype had no correlation with BC susceptibility. Haplotypes composed of rs920778–rs1899663 and rs920778–rs1899663–rs4759314 could increase BC risk (all P &lt; 0.001). There were no statistically significant associations between HOTAIR SNPs and clinicopathological characteristics. The rs920778 GG/AG genotypes were associated with worse disease-free survival (DFS) (p = 0.012), and the rs4759314 GA genotype was associated with worse DFS and overall survival (OS) (p = 0.011).ConclusionHOTAIR SNPs(rs920778 and rs4759314) are significantly related to BC susceptibility and prognosis in the northeastern Chinese population, indicating the significance in the occurrence and development of BC.
