Abstract
Breast cancer is one of the leading causes of mortality among women. The most frequently encountered tumors are luminal tumors. Associations of polymorphisms in the hOGG1 (rs1052133), APEX1 (rs1130409), XPD (rs13181), SOD2 (rs4880), and CAT (rs1001179) genes were studied in 313 nonsmoking postmenopausal patients with luminal B subtype breast cancer. The control group consisted of 233 healthy nonsmoking postmenopausal women. Statistically significant associations of the XPD and APEX1 gene polymorphisms with the risk of developing luminal B Her2-negative subtype of breast cancer were observed in a log-additive inheritance model, while the CAT gene polymorphism showed an association in a dominant inheritance model (OR = 1.41; CI 95 %: 1.08-1.85; Padj.= 0.011; OR = 1.39; CI 95 %: 1.07-1.81; Padj = 0.013 и OR = 1.70; CI 95 %: 1.19-2.43; Padj = 0.004, respectively). In the group of elderly women (aged 60-74 years), an association of the CAT gene polymorphism with the risk of developing luminal B subtype of breast cancer was found in a log-additive inheritance model (OR = 1.87; 95 % CI: 1.22-2.85; Padj = 0.0024). Using MDR analysis, the most optimal statistically significant 3-locus model of gene-gene interactions in the development of luminal B Her2-negative subtype breast cancer was found. MDR analysis also showed a close interaction and mutual enhancement of effects between the APEX1 and SOD2 loci and the independence of the effects of these loci from the CAT locus in the formation of luminal B subtype breast cancer.

Jia Z, Huang Y, Liu J, Liu G, Li J, Xu H, Jiang Y, Zhang S, Wang Y, Chen G, Qiao G, Li Y. Single nucleotide polymorphisms associated with female breast cancer susceptibility in Chinese population. Gene 2023; 884:147676. [PMID: 37524136 DOI: 10.1016/j.gene.2023.147676] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 05/09/2023] [Accepted: 07/28/2023] [Indexed: 08/02/2023]
Abstract
Breast cancer is a complex disease influenced by both external and internal factors, among which genetic factors play a critical role. Single-nucleotide polymorphisms (SNPs) are major contributors to the heritability of breast cancer, and their frequencies vary across ethnic groups. In this study, we aimed to investigate the association between 34 SNPs identified in previous genome-wide association studies (GWAS) and overall breast cancer risk, as well as breast cancer subtypes, in the Chinese female population. To accomplish this, we conducted an extensive association analysis using the high-throughput Sequenom MassARRAY® platform in a case-control study comprising 1848 breast cancer patients and 709 healthy controls. Our analysis, which utilized the SNPassoc package in R based on chi-squared (χ2) test and genetic model analysis, identified significant associations between breast cancer risk and SNP rs12493607 (TGFBR2, risk allele C, OR = 1.28 [1.11-1.47], P = 0.0005), as well as a less conservatively significant association with rs4784227 (CASC16, risk allele T, OR = 1.24 [1.08-1.42], P = 0.0017) and rs2046210 (ESR1, risk allele A, OR = 1.50 [1.16-1.95], P = 0.0016). Furthermore, our stratified analyses revealed that rs12493607 was significantly associated with invasive carcinoma, estrogen receptor (ER)-positive, progesterone receptor (PR)-positive, HER2-negative, and young (aged younger than 45) breast cancer. SNP rs4784227 and rs3803662 (CASC16) were associated with invasive carcinoma and ER-positive breast cancer, while rs2046210 was linked to ductal carcinoma in situ, ER-negative, PR-negative, HER2-positive, and elder (aged more than 45) breast cancers. SNPs rs10484919 (ESR1) and rs1038304 (CCDC170) showed links to HER2-positive breast cancer, and rs616488 (PEX14) with premenopausal breast cancer. In summary, our study shed light on the relationship between SNPs and breast cancer susceptibility within a vast Chinese cohort, supporting the development of polygenetic risk scores for the Chinese population. These findings provide valuable insights into the genetic basis of breast cancer and have important implications for risk prediction, early detection, and personalized treatment of this disease.

Abstract
Objective: Apurinic/apyrimidinic endonuclease 1 (APEX1), a key enzyme responsible for DNA base excision repair, has been linked to development and progression of cancers. In this work, we aimed to explore the role of APEX1 in hepatocellular carcinoma (HCC) and elucidate its molecular mechanism. Methods: The expression of APEX1 in HCC tissues and matched adjacent normal tissues (n = 80 cases) was evaluated by immunohistochemistry. Web-based tools UALCAN and the Kaplan-Meier plotter were used to analyze the Cancer Genome Atlas database to compare expression of APEX1 mRNA to 5-year overall survival. APEX1 was stably silenced in two HCC cell lines, Hep 3B and Bel-7402, with shRNA technology. An in vivo tumorigenesis model was established by subcutaneously injecting sh-APEX1-transfected Bel-7402 cells into mice, and tumor growth was determined. We performed high-throughput transcriptome sequencing in sh-APEX1-treated HCC cells to identify the key KEGG signaling pathways induced by silencing of APEX1. Results: APEX1 was significantly upregulated and predicted poor clinical overall survival in HCC patients. Silencing APEX1 inhibited the proliferation of HCC cells in vivo and in vitro, and it repressed invasion and migration and increased apoptosis and the percentage of cells in G1. Differentially expressed genes upon APEX1 silencing included genes involved in TNF signaling. A positive correlation between the expression of APEX1 and MAP2K6 was noted, and overexpressing MAP2K6 overcame cancer-related phenotypes associated with APEX1 silencing. Conclusion: APEX1 enhances the malignant properties of HCC via MAP2K6. APEX1 may represent a valuable prognostic biomarker and therapeutic target in HCC.

Abstract
The DNA repair genes have a crucial function in the base excision repair (BER) mechanism among different cancerous disorders, particularly hepatocellular carcinoma (HCC). The foremost objective of this study is to explore the association of genetic variants of the APEX1 p.Asp148Glu and the XRCC1 p.Gln399Arg with the susceptibility of HCC and to identify the computational bioinformatics frameworks of these missense variants. A total of 250 participants were enrolled in this study, including 150 HCC patients and 100 cancer-free controls. The genomic DNA was characterized and genotyped by applying the PCR-CTPP method. The frequency of the APEX1 (rs1130409*Glu) allele was statistically significant with increased risk of HCC (OR = 1.66, 95% CI = 1.12-2.45), while the XRCC1 (rs25487*Gln) allele conferred a protection against the progression of HCC (OR = 0.64, 95% CI = 0.42-0.96). Furthermore, HCC patients carrying the APEX1 p.Asp148Glu and the XRCC1 p.Gln399Arg variants indicated no significant difference with the clinical, and laboratory parameters (p > .05). Our findings confirmed that the APEX1 p.Asp148Glu variant was associated with increased risk of HCC, while the XRCC1 p.Gln399Arg variant revealed protection against the development of HCC.

Abstract
Apurinic/apyrimidinic endonuclease 1/redox-factor 1 (APE1/Ref-1) gene encodes a multifunctional protein involved in the DNA base excision repair (BER) pathway, which initiates repair of apurinic/apyrimidinic (AP) sites in DNA by catalyzing hydrolytic incision of the phosphodiester backbone. APE1/Ref-1 polymorphisms are related to the occurrence of neural tube defects (NTDs), but the association between APE1/Ref-1 polymorphisms and NTDs is not reported in Chinese Han population. The aim of the present study was to evaluate the association of APE1/Ref-1 polymorphism and the risk of NTD occurrence for Han population in a high-risk area of China. APE1/Ref-1 genotypes were determined by iPLEX Gold SNP genotyping. AP sites and folate level of brain tissues were measured. The results showed that three polymorphisms (rs3136817, rs77794916, and rs1760944) of APE1/Ref-1 were statistically associated with NTD subtypes. Allele C of rs3136817, allele T of rs77794916, and allele G of rs1760944 were associated with an increased risk for encephalocele (OR = 2.52, 95% CI [1.25-5.07], P < 0.01; OR = 1.80, 95% CI [1.04-3.12], P = 0.04; and OR = 1.96, 95% CI [1.12-3.45], P = 0.02), compared with those harboring the alleles T, C, and T, respectively. The folate level in NTDs was lower than that in controls. DNA AP sites in the encephalocele were significantly higher than the control (P < 0.01). The three polymorphisms of APE1/Ref-1 were significantly related to NTD occurrence, which indicated that APE1/Ref-1 might be a potential genetic risk factor for encephalocele in a high-risk area of NTDs in China.

Abstract
Background 8-Oxo-7, 8-dihydro-2'-deoxyguanosine (8-oxodG) is a potent DNA damage marker that leads to cellular oxidative stress. It is a DNA-repair enzyme that participates in "8-oxodG" DNA adducts removal. Previous studies show weak associations of rs1052133 (hOGG1) in breast cancer patients of Northern India. We performed this study to explore the variant rs1052133 (hOGG1) with breast in the population of Jammu and Kashmir (J and K). Method A polymerase chain reaction-restriction fragment length polymorphism -based single-nucleotide polymorphism (SNP) genotypic study was carried out in peripheral blood samples of 165 breast cancer patients and 200 healthy controls, using specific primers. Sanger sequencing verified the results. Results hOGG1-Ser326Cys polymorphism occurred frequently in cases as compared with controls. Data were evaluated by SPSS V.13 software, following Hardy-Weinberg equilibrium (P = 0.002 at OR 2.57; 95% CI [1.68-3.93]), which showed that the SNP rs1052133 had a significant association with increased risk of breast cancer. Conclusion Overall, the results of this analysis show that the hOGG1-Ser326Cys polymorphism may be associated with an increased risk for breast cancer in the J and K population.

Abstract
Sarcomas are highly aggressive cancers that have a high propensity for metastasis, fail to respond to conventional therapies, and carry a poor 5-year survival rate. This is particularly true for patients with neurofibromatosis type 1 (NF1), in which 8%–13% of affected individuals will develop a malignant peripheral nerve sheath tumor (MPNST). Despite continued research, no effective therapies have emerged from recent clinical trials based on preclinical work. One explanation for these failures could be the lack of attention to intra-tumoral heterogeneity. Prior studies have relied on a single sample from these tumors, which may not be representative of all subclones present within the tumor. In the current study, samples were taken from three distinct areas within a single tumor from a patient with an NF1-MPNST. Whole exome sequencing, RNA sequencing, and copy number analysis were performed on each sample. A blood sample was obtained as a germline DNA control. Distinct mutational signatures were identified in different areas of the tumor as well as significant differences in gene expression among the spatially distinct areas, leading to an understanding of the clonal evolution within this patient. These data suggest that multi-regional sampling may be important for driver gene identification and biomarker development in the future.

Abstract
Neuroblastoma is a life-threatening extracranial solid tumor, preferentially occurring in children. However, its etiology remains unclear. APEX1 is a critical gene in the base excision repair (BER) system responsible for maintaining genome stability. Given the potential effects of APEX1 polymorphisms on the ability of the DNA damage repair, many studies have investigated the association between these variants and susceptibility to several types of cancer but not neuroblastoma. Here, we conducted a three-center case-control study to evaluate the association between APEX1 polymorphisms (rs1130409 T>G, rs1760944 T>G, and rs3136817 T>C) and neuroblastoma risk in Chinese children, consisting of 469 cases and 998 controls. Odds ratio (OR) and 95% confidence intervals (CIs) were calculated to evaluate the associations. No significant association with neuroblastoma risk was found for the studied APEX1 polymorphisms in the single locus or combination analysis. Interestingly, stratified analysis showed that rs1130409 GG genotype significantly reduced the risk of tumor in males. Furthermore, we found that carriers with 1-3 protective genotypes had a lower neuroblastoma risk in the children older than18 months and male, when compared to those without protective genotypes. In summary, our data indicate that APEX1 gene polymorphisms may have a weak effect on neuroblastoma susceptibility. These findings should be further validated by well-designed studies with larger sample size.
