Transcription Factor 21 (TCF21) rs12190287 Polymorphism is Associated with Osteosarcoma Risk and Outcomes in East Chinese Population.

ABSTRACT: BACKGROUND The transcription factor 21 (TCF21) gene is believed to be a tumor suppressor gene. TCF21 gene polymorphisms were found to play a role in the tumorigenesis of some solid malignancies. We raised a hypothesis that genetic polymorphisms of TCF21 were correlated with risk and prognosis of osteosarcoma. MATERIAL AND METHODS We recruited 225 young osteosarcoma individuals and 250 cancer-free controls. Five tagging SNPs (TCF21 rs2327429 T>C, rs2327433 A>G, rs2327433 A>G, rs12190287 C>G, and rs4896011 T>A) were genotyped. Preserved DNA samples from blood underwent PCR analysis for genotyping. RESULTS rs12190287 C>G is a good predictor of osteosarcoma risk and outcomes. The CG and GG genotypes of rs12190287 predict elevated risk of osteosarcoma. Besides, rs12190287 CG and GG genotypes are associated with Enneking stage and potential in forming metastasis of osteosarcoma. CONCLUSIONS Genetic polymorphisms of TCF21 are potentially predictive for osteosarcoma risk and outcomes.

Project description:Various loci and genes that confer susceptibility to coronary artery disease (CAD) have been identified mainly in Caucasian populations by genome-wide association studies (GWASs). As hypertension is a major risk factor for CAD, certain polymorphisms may contribute to the genetic susceptibility to CAD through affecting the predisposition to hypertension. The aim of the present study was to examine a possible association of hypertension with 29 single-nucleotide polymorphisms (SNPs) previously identified by meta-analyses of GWASs as susceptibility loci for CAD. Study subjects comprised of 5,460 individuals (3,348 subjects with hypertension and 2,112 controls). The genotypes of SNPs were determined by the multiplex bead-based Luminex assay. The ?2 test revealed that genotype distributions and allele frequencies for rs12190287 of the transcription factor 21 gene (TCF21) and rs1122608 of the SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily a, member 4 gene (SMARCA4) were significantly (P<0.05) associated with hypertension. Allele frequencies for rs9369640 of the phosphatase and actin regulator 1 gene (PHACTR1) and genotype distributions for rs599839 of the proline/serine-rich coiled-coil 1 gene (PSRC1) were also significantly associated with hypertension. Multivariable logistic regression analysis with adjustment for age, gender, body mass index and smoking status revealed that rs12190287 of TCF21 (P=0.0014; recessive model; odds ratio, 1.21) was significantly associated with hypertension, and the C allele represented a risk factor for this condition. Similar analyses revealed that rs1122608 of SMARCA4 (P=0.0305; dominant model; odds ratio, 0.86), rs9369640 of PHACTR1 (P=0.0119; dominant model; odds ratio, 0.82) and rs599839 of PSRC1 (P=0.0248; dominant model; odds ratio, 0.84) were also related to hypertension, with the minor T, C and G alleles, respectively, being protective against this condition. Thus, the present results indicate that rs12190287 (G?C) of TCF21 is a susceptibility locus for hypertension.

Project description:BACKGROUND:The single nucleotide polymorphisms of interleukin-21 (IL-21) gene were confirmed to be related to various diseases, but no studies have examined the possible role of IL-21 single nucleotide polymorphisms (SNPs) (rs907715, rs2221903, and rs12508721) in gastric precancerous lesions. AIM:To explore the associations between SNPs of IL-21 gene (rs907715, rs2221903, and rs12508721) and gastric precancerous lesions in a Chinese population. METHODS:Three SNPs of IL-21 were genotyped using polymerase chain reaction-ligase detection reaction in 588 cases and 290 healthy controls from May 2013 to December 2016 in northwestern China. Gastric precancerous lesions were confirmed by endoscopic examination and categorized as non-atrophic gastritis, atrophic gastritis, and intestinal metaplasia. Descriptive statistic and logistic regression were used for data analyses. RESULTS:IL-21 rs907715 genotype CC and C frequencies were higher in in patients with gastric precancerous lesions than in the controls (OR = 1.59, 95%CI: 1.06-2.38, P = 0.013; OR = 1.28, 95%CI: 1.01-2.22, P = 0.044, respectively) after adjusting for confounding factors. For SNP rs907715 in intestinal metaplasia patients, significant differences between cases and controls were observed in the frequencies of genotype CC and C (OR = 1.92, 95%CI: 1.24-2.98, P = 0.004; OR = 1.53, 95%CI: 1.04-2.24, P = 0.028, respectively); for non-atrophic gastritis and atrophic gastritis patients, the CC and C genotypes showed no significant association with risk in all models. No association between either rs2221903 or rs12508721 and gastric precancerous lesions was found in the present study. In the haplotype analysis, the TC haplotype (rs907715 and rs12508721) and TT haplotype (rs2221903 and rs907715) were more frequent in the case group than control group (P < 0.05). CONCLUSION:Our findings indicate that SNP rs907715 of IL-21 gene is associated with gastric precancerous lesions. The TC haplotype (rs907715 and rs12508721) and TT haplotype (rs2221903 and rs907715) increased the risk of gastric precancerous lesions. If confirmed, these findings will shed light on the etiology of precancerous lesions.
