Abstract
The incidence of thyroid cancer, one of the most common forms of endocrine cancer, is increasing rapidly worldwide in developed and developing countries. Various risk factors can increase susceptibility to thyroid cancer, but particular emphasis is put on the role of DNA repair genes, which have a significant impact on genome stability. Polymorphisms of these genes can increase the risk of developing thyroid cancer by affecting their function. In this article, we present a concise review on the most common polymorphisms of selected DNA repair genes that may influence the risk of thyroid cancer. We point out significant differences in the frequency of these polymorphisms between various populations and their potential relationship with susceptibility to the disease. A more complete understanding of these differences may lead to the development of effective prevention strategies and targeted therapies for thyroid cancer. Simultaneously, there is a need for further research on the role of polymorphisms of previously uninvestigated DNA repair genes in the context of thyroid cancer, which may contribute to filling the knowledge gaps on this subject.

Abstract
Thyroid cancer is the most common malignant tumor of the endocrine system, and its incidence is increasing worldwide each year. This study aimed to explore the association between XRCC1, GSTM1, and GSTT1 polymorphisms in the model of thyroid cancer. The experiment was conducted by searching PubMed, Embase, and Web of Science, with the last search performed in March 2022. A total of 12 studies were included in this meta-analysis, with sample sizes ranging from 211 to 1124. The proportion of XRCC1 polymorphisms (rs25489, GG) in thyroid cancer was slightly lower than that of the normal control group, but the difference was not statistically significant (Mean difference=1.13, 95% CI: 0.99-1.28, p=0.08). The proportion of XRCC1 polymorphisms (rs25489, GA) in thyroid cancer was significantly lower than that of the normal control group (Mean difference=1.32, 95% CI: 1.16-1.52, p<0.00001). The proportion of XRCC1 polymorphisms (rs25489, AA) in thyroid cancer was slightly lower than that of the normal control group, but again, the difference was not statistically significant (Mean difference=0.78, 95% CI: 0.61-1.01, p=0.06). Similarly, the proportion of XRCC1 polymorphisms (rs25487, GG) and (rs25487, GA) in thyroid cancer was lower than that of the normal control group, but the differences were not statistically significant (p=0.22 and p=0.49, respectively). In conclusion, this study found that the proportion of XRCC1 polymorphisms (rs25489, AA) in thyroid cancer was lower than that of the normal control group.

Abstract
The definition of an exclusive panel of genetic markers is of high importance to initially detect among this review population. Therefore, we gave a summary of each main genetic marker among Iranian patients with thyroid cancer for the first time which were classified based on their cellular function. Due to the results, a significant relationship was found between SNP in codons 194, 280, and 399 (XRCC1), Allele 3434Thr (XRCC7), GC or CC genotype 31, G/C (Survivin), 399G>A (XRCC1), Tru9I (vitamin D receptor), G-D haplotype (MDM2), TT genotype, -656 G/T (IL-18), TAGTT haplotype (IL-18), G allele in +49 A>G (CTLA-4), +7146 G/A (PD-1.3), +7785 C/T (PD-1.5), rs1143770 (let7a-2), rs4938723 (pri-mir-34b/c) genes, and thyroid cancers. Moreover, SNP in 677C-->T (MTHFR), GG genotype Asp1312Gly (thyroglobulin), 2259C>T (Rad52), R188H, (XRCC2), T241M (XRCC3) had higher risks of thyroid cancer and lower risks were observed in -16 Ins-Pro (p53), rs3742330 (DICER1). At last, the protective effects were explored in 127 CC genotype (IL-18), rs6877842 (DROSHA). Conduct further studies on the types of DNA repair gene polymorphisms with a larger number in the thyroid cancer using modern methods such as SNP array so that these genes could be used as a biomarker in prediction, diagnosis, and treatment of thyroid cancer. This review presents for the first time a summary of important genetic markers in Iranian patients with thyroid cancer.

Risk of Colorectal Carcinoma May Predispose to the Genetic Variants of the GST, CYP450, and TP53 Genes Among Nonsmokers in the Saudi Community. Int J Gen Med 2021; 14:1311-1323. [PMID: 33883929 PMCID: PMC8055278 DOI: 10.2147/ijgm.s294802] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Accepted: 03/25/2021] [Indexed: 02/05/2023] Open
Abstract
PURPOSE Colorectal carcinoma (CRC) represents a considerable public health burden in Saudi Arabia. Several candidate genes and genetic variants have been associated with morbidity and mortality among patients with CRC. We explored whether allelic variants of the GSTM1, GSTT1, CYP450 (rs4646903 and rs1048943), and TP53 (rs1042522) genes predisposed nonsmoking Saudi individuals to increased risk for CRC. PATIENTS AND METHODS DNA from buccal cells of 158 participants (80 with CRC and 78 healthy controls) were analyzed for five SNPs using conventional PCR and TaqMan genotyping assays. The SNPStats software was utilized to choose the best interactive inheritance mode for selected SNPs (https://www.snpstats.net). RESULTS The mean age of diagnosis was 62.4±13.5 years (range, 40-83 years), with those aged 71-80 years and those aged 40-50 years accounting for the most diagnoses (35.7% and 28.6% of diagnosis, respectively). The GSTM1 and TP53 rs1042522 SNPs were associated with CRC (OR= 3.7; P< 0.0001, and OR= 1.6; P= 0.033, respectively). A plausible contribution to CRC was observed for the GSTM1 and TP53 rs1042522 SNPs (x 2 Yates= 14.7; P= 0.00013, and x 2 Yates= 11.2; P= 0.0008, respectively), while the GSTT1 null variant did not affect risk. Heterozygosity in the CYP450 (rs4646903 and rs1048943 SNPs) was associated with a significant risk for CRC. The GSTM1/GSTT1 and CYP450 rs4646903/rs1048943 SNP pairs were in linkage disequilibrium, and the associations were statistically significant (P= 0.01 and P= 4.6x10‒7, respectively). CONCLUSION The GSTM1 and TP53 rs1042522 variants can increase the development of CRC in Saudi nonsmokers. Even the presence of one copy of a variant allele in the CYP1A1 gene can predispose CRC risk. Additional studies should also examine other SNP combinations with lifestyle factors that may help prevent, rather than facilitate, colorectal tumorigenesis.

Abstract
Non-nucleoside reverse transcriptase inhibitors are metabolized in the liver by cytochrome P450 (CYP) isoenzymes. Variations in the genes encoding these enzymes may influence the activity of corresponding metabolizing enzymes. This study aimed at assessing association of CYP2C9*2 430C/T, CYP2C9*31075A/C, and CYP1A1m1 3801T/C polymorphism with risk to develop ARV Antiretroviral-associated hepatotoxicity and its severity. In this case-control study, genotyping of CYP2C9*2, CYP2C9*3, and CYP1A1m1 genes was done in 34 HIV-infected individuals with hepatotoxicity and 131 without hepatotoxicity, and 153 unrelated healthy individuals using PCR-RFLP. CYP1A1m13801CC genotype was likely to be associated with severe ARV-associated hepatotoxicity (OR = 1.78, p = 0.70). CYP1A1m13801CC genotype and combined genotype TC + CC were likely to be associated with development of ARV-associated hepatotoxicity (OR = 2.57, p = 0.08; OR = 1.42, p = 0.17). CYP1A1m1 3801CC genotype among advanced and intermediate HIV disease stage was likely to be associated with advancement of disease (OR = 2.56, p = 0.77; OR = 2.37, p = 0.45). CYP2C9*31075AC genotype among alcohol users was likely to be associated with development of ARV-associated hepatotoxicity (OR = 1.67, p = 0.38). CYP1A1m1 3801TC genotype and combined genotype TC + CC among nevirapine users were likely to be associated with severe ARV-associated hepatotoxicity (OR = 3.68, p = 0.27; OR = 4.91, p = 0.13). Among those who received nevirapine, presence of CYP1A1m1 3801TC genotype was likely to be associated with increased risk of development of ARV-associated hepatotoxicity (OR = 1.50, p = 0.78). CYP1A1m1 3801TC, 3801CC, and CYP2C9*3 1075AC genotypes among combined alcohol + nevirapine users increased the risk of development of ARV-associated hepatotoxicity (OR = 1.41, p = 0.53; OR = 1.49, p = 0.83; OR = 1.78, p = 0.35). In conclusion, individuals with CYP1A1m13801CC and 3801TC genotypes independently and in the presence of alcohol and nevirapine usage is likely to be associated with increased risk of development of ARV-associated hepatotoxicity, its severity, and advancement of disease. CYP2C9*31075AC genotype with combined alcohol and nevirapine usage indicated a risk for development of ARV-associated hepatotoxicity.

Abstract
In first part of this study, a systematic review was designed to explore the involvement of CYP1A1 and GSTP1 genes in breast cancerogenesis. Based on systematic review, we designed a study to screen CYP1A1 and GSTP1 genes for mutation and their possible association with breast carcinogenesis. A total of 400 individuals were collected and analyzed by PCR-SSCP. After sequence analysis of coding region of CYP1A1 we identified eleven mutations in different exons of respective gene. Among these eleven mutations, ~3 folds increased breast cancer risk was found associated with Asp82Glu mutation (OR 2.99; 95% CI 1.26-7.09), with Ser83Thr mutation (OR 2.99; 95% CI 1.26-7.09) and with Glu86Ala mutation (OR 3.18; 95% CI 1.27-7.93) in cancer patients compared to controls. Furthermore, ~4 folds increase in breast cancer risk was found associated with Asp347Glu, Phe398Tyr and 5178delT mutations (OR 3.92; 95% CI 1.35-11.3) in patients compared to controls. The sequence analysis of GSTP1 resulted in identification of total five mutations. Among these five mutations, ~3 folds increase in breast cancer risk was observed associated with 1860G>A mutation, with 1861-1876delCAGCCCTCTGGAGTGG mutation (OR 2.70; 95% CI 1.10-6.62) and with 1861C>A mutation (OR 2.97; 95% CI 1.01-8.45) in cancer patients compared to controls. Furthermore, ~5 folds increase in breast cancer risk was associated with 1883G>T mutation (OR 4.75; 95% CI 1.46-15.3) and ~6 folds increase in breast cancer risk was found associated with Iso105Val mutation (OR 6.43; 95% CI 1.41-29.3) in cancer patients compared to controls. Our finding, based on systematic review and experimental data suggest that the polymorphic CYP1A1 and GSTP1 genes may contribute to risk of developing breast cancer.

Abstract
Association of P53 polymorphisms with the increased risk of various cancers has been investigated in numerous studies. However, the results were conflicting and no polymorphism has been determined as a definite risk factor. It is likely that the study of P53 combined genotypes and haplotypes may be more useful than individual polymorphisms. Thus, in this study, we analyzed the associations of intron 3 Ins16bp and exon 4 Arg72Pro polymorphisms, as well as their combined genotypes and haplotypes with the risk of differentiated thyroid carcinoma in Iranian-Azeri patients. This case-control study was performed on 84 Iranian Azeri patients with differentiated thyroid carcinoma and 150 healthy subjects. Intron 3 genotype was determined using PCR products analysis on polyacrylamide gels and AS-PCR was used for genotyping Arg72Pro polymorphism. The javastat online statistics package software and SHEsis program were applied for data analysis. There was no significant difference in genotype frequencies of both two polymorphisms between cases and controls. However, the (-16 ins/-16 ins) (Arg/Pro) genotype combination had a noticeable but not significant association with decreased risk of thyroid cancer development (OR = 0.497 95%CI: 0.209-1.168 P = 0.080) and also the frequency of (-16 ins-Pro) haplotype was significantly higher in controls rather than patients (OR = 0.543 95%CI: 0.326-0.903 P = 0.018). In our study, there was association between (-16 ins-Pro) haplotype with decreased risk of differentiated thyroid carcinoma development in Iranian-Azeri patients.

Abstract
Korea has the highest incidence of thyroid cancer of any nation. We conducted a population-based, case-control study of the association between the risk of papillary thyroid cancer (PTC) in the Korean population and polymorphisms of methylenetetrahydrofolate reductase (MTHFR) C677T, glutathione S-transferase class mu (GSTM1), and glutathione S-transferase class theta (GSTT1). The study subjects consisted of 2,194 newly diagnosed PTC cases and 1,669 population-based healthy controls. Odds ratios adjusted by age, sex, body mass index, smoking, drinking, serum thyroid-stimulating hormone level, family history of thyroid cancer, and previous history of thyroid disease, with 95% confidence intervals, were estimated using logistic regression analysis. The frequencies of MTHFR 677TT genotypes, and null genotypes of GSTM1 and GSTT1 were 19.2, 56.8, and 51.4% among PTC cases and 17.4, 54.1, and 50.6% among the controls, respectively. No significant associations between PTC and TT genotypes of MTHFR C677T, null genotypes of GSTM1 and GSTT1, or double-null (GSTM1-GSTT1) genotypes were found. These findings suggest that polymorphisms of the MTHFR C677T, GSTM1 and GSTT1 genotypes do not contribute to the development of PTC susceptibility in the Korean population.

Abstract
TP53 Arg72Pro polymorphism has been proposed to have some effects on host's susceptibility to cancer. Several studies were published to assess the association between TP53 Arg72Pro polymorphism and thyroid carcinoma, but they reported controversial results. We performed a systemic review and meta-analysis to assess the association between TP53 Arg72Pro polymorphism and thyroid carcinoma. Odds ratio (OR) with 95% confidence interval (95% CI) was used to assess the association. Fourteen individual studies with 3,483 subjects were finally included into the meta-analysis. Overall, there was an obvious association between TP53 Arg72Pro polymorphism and thyroid carcinoma under the recessive model (ProPro vs. ArgArg/ArgPro, OR = 2.02, 95% CI 1.13 to 3.62, P = 0.02). Subgroup analysis by race showed that TP53 Arg72Pro polymorphism was associated with thyroid carcinoma in Caucasians (ProPro vs. ArgArg/ArgPro, OR = 2.31, 95% CI 1.08 to 4.93, P = 0.03). Subgroup analysis by histological type showed that TP53 Arg72Pro polymorphism was not associated with a risk of different types of thyroid carcinoma. In summary, the meta-analysis suggests that TP53 Arg72Pro polymorphism is associated with thyroid carcinoma risk in Caucasians. Besides, more studies with large sample size are needed to further assess the associations above.

PubMed, EMBASE, Cochrane Library, and HuGNet database were searched up to November 2011 using the appropriate terms. Twelve studies regarding GSTM1 null polymorphism (1569 cases and 2907 controls), 11 studies concerning GSTT1 null polymorphism (1515 cases and 2863 controls), and 8 studies on GSTP1 Ile105Val (965 cases and 1604 controls) were included in the meta-analysis. The random effects odds ratio was 1.07 (95% CI: 0.88-1.31; I(2) = 54.1%, P for heterogeneity = 0.013) for the GSTM1 null vs. present genotype and 1.08 (95% CI: 0.75-1.57; I(2) = 81.4%, P for heterogeneity < 0.001) for the GSTT1 null vs. present genotype, and 1.02 (95% CI: 0.70-1.49; I(2) = 74.6%, P for heterogeneity < 0.001) for the GSTP1 Val/Val+Val/Ile vs. Ile/Ile genotype. Similarly, no significant associations were demonstrated for subgroup analyses performed by ethnicity and histological type. In conclusion, these three polymorphisms are unlikely to be major determinants of susceptibility to thyroid cancer. Reasons for potential heterogeneity of effects, which could include true biologic heterogeneity, publication bias, or chance, deserve further investigation. The relationship between these three genes and thyroid carcinoma must be evaluated further with gene-gene and gene-environment interactions.
