Association Between the Asp312Asn, Lys751Gln, and Arg156Arg Polymorphisms inXPDand the Risk of Prostate Cancer

Abstract

Prostate cancer is the most common solid cancer and genetic factors play important roles in its pathogenesis. XPD is one of the 8 core genes involved in the nucleotide excision repair pathway. The relationship between Asp312Asn, Lys751Gln, and Arg156Arg polymorphisms in XPD and prostate cancer risk is a controversial topic. Therefore, we conducted a meta-analysis to explore the relationship between these 3 polymorphisms and the risk of developing prostate cancer. We searched the electronic literature in PubMed and Google Scholar for all relevant studies (last updated January 1, 2017). The pooled odds ratios and 95% confidence intervals for the associations between the Asp312Asn, Lys751Gln, or Arg156Arg polymorphisms in XPD and prostate cancer risk were calculated. To evaluate the effects of specific study characteristics on the association of these 3 polymorphisms and prostate cancer risk, we performed subgroup analysis if 2 or more studies were available. After an extensive literature review, 7 publications regarding Asp312Asn genotype distribution with 8 case–controls, 9 publications regarding Lys751Gln genotype distribution with 10 case–controls, and 3 publications regarding Arg156Arg genotype distribution with 4 case–controls were selected. The results showed that Asp312Asn (odds ratio = 1.34, 95% confidence interval: 0.96-1.87, P = .000), Lys751Gln (odds ratio = 0.98, 95% confidence interval: 0.89-1.08, P = .986), and Arg156Arg (odds ratio = 1.05, 95% confidence interval: 0.91-1.22, P = .57) polymorphisms do not increase the risk of prostate cancer in the dominant model. Further, in the subgroup analysis by ethnicity, no relationships were observed between Lys751Gln and Arg156Arg polymorphisms and prostate cancer risk. However, stratified analysis by ethnicity revealed that Asp312Asn affects African (odds ratio = 1.57, 95% confidence interval: 1.06-2.33, P = .382) and Asian populations (odds ratio = 2.09, 95% confidence interval: 1.39-3.14, P = .396) in homozygote comparison. In conclusion, this meta-analysis suggests that there is no general association between the Asp312Asn, Lys751Gln, and Arg156Arg polymorphisms in XPD and prostate cancer susceptibility.

A Drosophila platform identifies a novel, personalized therapy for a patient with adenoid cystic carcinoma

“…ERCC2 encodes XPD, a protein associated with regulation of TFIIH-mediated transcription and DNA damage. XPD has effects on progression of a broad palette of tumor types when mutated or altered—increased or decreased—in expression, and variants in ERCC2 have been associated with altered drug response, especially platinum-based therapies ( Du et al., 2014 ; Fu et al., 2017 ; Tan et al., 2017 ; Pajuelo-Lozano et al., 2018 ; Liu et al., 2019 ). This may have contributed to the patient's failure to respond to earlier carboplatin-based therapy.…”

Impact of Polymorphism in Base Excision Repair and Nucleotide Excision Repair Genes and Risk of Cervical Cancer: A Case-Control Study

“…The polymorphism in NER pathway genes are also demonstrated by other researchers for their involvement in development of breast (Samson et al, 2010), lung (Jin et al, 2014) and gastric cancer (Zhou et al, 2021). However, the evidences are inconsistent where some SNPs showed increased risk of certain cancers whereas other revealed no association same SNPs with other type of cancer such as gastric association of same SNPs (Hua et al, 2016), prostate (Fu et al, 2017) and breast (Yumei et al, 2020). Similarly, Indian studies also signified the role of SNPs of BER genes in development of lung (Uppal et al, 2014), head and neck (Choudhury et al, 2014), gastric (Ghosh et al, 2016) and breast cancer (Nagpal et al, 2020).…”

“…Cervical cancer burden is reported to be huge in low income countries.Different SNPs of BER and NER genes have been frequently studied for their role in determining cancer risk, but still there remained uncertainty in their precise association with other cancerswhere inconsistent the data pointed both increased or decreased risks (Hua et al, 2016;Fu et al, 2017;Yumei et al, 2020). In view of these conflicting results we examined the genotypic frequencies of BER and NER genes in a case-control study from rural women of south-western Maharashtra.…”
