Abstract
Objective Neuroblastoma is a life-threatening pediatric solid tumor whose etiology remains unclear. N7-methylguanosine (m7G) is one of the most important epigenetic modifications of RNA, which plays a crucial role in tumorigenesis. The m7G-mediated genes METTL1 and WDR4 also have been reported to be dysregulated in various cancers. However, the implications of METTL1 and WDR4 in neuroblastoma have not been clarified. Methods Given the oncogenic potential of m7G modification, we performed a case-control study to assess the association of METTL1 and WDR4 genes polymorphisms with neuroblastoma risk in a Chinese population consisting of 402 cases and 473 controls. Odds ratios (ORs) and 95 % confidence intervals (CIs) were applied to evaluate the associations between studied polymorphisms and neuroblastoma risk. The adjusted odds ratio (AOR) was adjusted for age and gender. Results Overall, four polymorphisms were significantly associated with neuroblastoma risk, including METTL1 rs2291617 (recessive model: adjusted OR = 1.59, 95 % CI = 1.08-2.34, P = 0.019), WDR4 rs2156316 (dominant model: adjusted OR = 0.74, 95 % CI = 0.57-0.97, P = 0.028), WDR4 rs6586250 (dominant model: adjusted OR = 0.59, 95 % CI = 0.42-0.84, P = 0.004) and WDR4 rs15736 (dominant model: adjusted OR = 0.60, 95 % CI = 0.42-0.85, P = 0.004). Stratified analysis showed stronger correlations between significant polymorphisms and neuroblastoma risk among subgroups divided by age, gender, tumor origin, and clinical stage. Furthermore, expression quantitative trait loci (eQTL) analysis revealed that significant polymorphisms were associated with the expression of the adjacent genes. Conclusions Our study indicated that four polymorphisms in m7G-mediated genes contribute to neuroblastoma susceptibility in the eastern Chinese population. However, our findings should be verified further by large-scale and well-designed studies.

WDR4 gene polymorphisms and Wilms tumor susceptibility in Chinese children: A five-center case-control study. J Cancer 2023; 14:1293-1300. [PMID: 37283791 PMCID: PMC10240673 DOI: 10.7150/jca.83747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Accepted: 04/27/2023] [Indexed: 06/08/2023] Open
Abstract
Wilms tumor is the most common embryonal renal malignancy in children. WDR4 is an indispensable noncatalytic subunit of the RNA N7-methylguanosine (m7G) methyltransferase complex and plays an essential role in tumorigenesis. However, the relationship between polymorphisms in the WDR4 gene and susceptibility to Wilms tumor remains to be fully investigated. We performed a large case-control study involving 414 patients and 1199 cancer-free controls to investigate whether single nucleotide polymorphisms (SNPs) in the WDR4 gene are associated with Wilms tumor susceptibility. WDR4 gene polymorphisms (rs2156315 C > T, rs2156316 C > G, rs6586250 C > T, rs15736 G > A, and rs2248490 C > G) were genotyped using the TaqMan assay. In addition, unconditioned logistic regression analysis was performed, odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the association between WDR4 gene SNPs and Wilms tumor susceptibility as well as the strength of the associations. We found that only the rs6586250 C>T polymorphism was significantly associated with an increased risk of Wilms tumor (adjusted OR=2.99, 95% CI = 1.28-6.97, P = 0.011 for the rs6586250 TT genotype; adjusted OR=3.08, 95% CI = 1.33-7.17, P = 0.009 for the rs6586250 CC/CT genotype). Furthermore, the stratification analysis revealed that patients with the rs6586250 TT genotype and carriers with 1-5 risk genotypes exhibited statistically significant associations with increased Wilms tumor risk in specific subgroups. However, the rs2156315 CT/TT genotype was identified as having a protective effect against Wilms tumor in the age >18 months subgroup compared with the rs2156315 CC genotype. In brief, our study demonstrated that the rs6586250 C > T polymorphism of the WDR4 gene was significantly associated with Wilms tumor. This finding may contribute to the understanding of the genetic mechanism of Wilms tumor.

Association of RNA m 7G Modification Gene Polymorphisms with Pediatric Glioma Risk. BIOMED RESEARCH INTERNATIONAL 2023; 2023:3678327. [PMID: 36733406 PMCID: PMC9889142 DOI: 10.1155/2023/3678327] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 01/14/2023] [Accepted: 01/20/2023] [Indexed: 01/26/2023]
Abstract
Glioma stemming from glial cells of the central nervous system (CNS) is one of the leading causes of cancer death in childhood. The genetic predisposition of glioma is not fully understood. METTL1-WDR4 methyltransferase complex is implicated in tumorigenesis by catalyzing N7-methylguanosine (m7G) modification of RNA. This study is aimed at determining the association of glioma risk with three polymorphisms (rs2291617, rs10877013, and rs10877012) in METTL1 and five polymorphisms (rs2156315 rs2156316, rs6586250, rs15736, and rs2248490) in WDR4 gene in children of Chinese Han. We enrolled 314 cases and 380 controls from three independent hospitals. Genotypes of these polymorphisms were determined using the TaqMan assay. We found the WDR4 gene rs15736 was significantly associated with reduced glioma risk (GA/AA vs. GG: adjusted odds ratio = 0.63, 95%confidence interval = 0.42 - 0.94, P = 0.023) out of the eight studied polymorphisms. Stratified analyses showed that the association of rs15736 with the risk of glioma remained significant in children aged 60 months or older, girls, the subgroups with astrocytic tumors, or grade I + II glioma. We also found the combined effects of five WDR4 gene polymorphisms on glioma risk. Finally, expression quantitative trait locus (eQTL) analyses elucidated that the rs15736 polymorphism was related to the expression level of WDR4 and neighboring gene cystathionine-beta-synthase (CBS). Our finding provided evidence of a causal association between WDR4 gene polymorphisms and glioma susceptibility in Chinese Han children.
