Abstract
Background Cervical cancer is known to be the fourth most common cancer among women globally. In various factors, genetic factors have been considered as one major risk factor for cervical cancer. The research of genetic susceptibility to cervical cancer can be greatly helpful in studying the complex mechanism. This study was conducted to identify whether polymorphic variants of p73 G4C14-A4T14 and tumor protein p53 (p53) codon 72, either independently or jointly, might be associated with the risk of cervical cancer. Methods The genotypes of p73 G4C14-A4T14 and p53 codon 72 polymorphisms of peripheral blood DNA from 190 cervical cancer patients and 210 controls were investigated using polymerase chain reaction with confronting two-pair primers and polymerase chain reaction-restriction fragment length polymorphism, respectively. Results The frequency of p73 G4C14-A4T14 AT/AT (P = 0.013) or p53 codon 72 GG (P = 0.026) genotype was associated with an increased risk of cervical cancer by comparing with the p73 G4C14-A4T14 GC/GC or p53 codon 72 CC genotype, respectively. In addition, the interaction between the p73 G4C14-A4T14 and p53 codon 72 polymorphisms increased the risk of cervical cancer in a multiply manner, with the odds ratio being 3.692 (95% confidence interval =2.106-6.473) for subjects carrying both p73 G4C14-A4T14 GC/AT+AT/AT and p53 codon 72 GG genotypes. Conclusion These results suggest that there is a statistical difference between p73 and p53 gene polymorphism and the risk of cervical cancer in Chinese women, and there is a potential gene-gene interaction in the incidence of cervical cancer.

Abstract
As a member of the p53 gene family, the p73 gene can affect an individual's susceptibility to cancer through a p53-like manner. DNA sequence variation in the p73 gene has been reported to be associated with cancer risk. The present study aimed to identify whether the p73 gene G4C14-to-A4T14 single nucleotide polymorphism (SNP) is associated with risk of cervical cancer in a Chinese population. The p73 G4C14-to-A4T14 polymorphism was genotyped in 175 cervical cancer and 189 healthy control peripheral blood DNA samples using high resolution melting, polymerase chain reaction with confronting two-pair primers and direct DNA sequencing. The results demonstrated that carriers of the AT/AT genotype were associated with a significantly increased risk of cervical cancer (P=0.042; χ2=4.122; odds ratio = 2.241; 95% confidence interval = 1.013-4.956) compared with the GC/GC genotype carriers. In addition, there was a significant association between p73 genotypes and tumor size in patients with cervical cancer (P=0.014; χ2=8.607). However, no association was identified between p73 genotypes and tumor stage, histological type or lymph node metastasis in patients with cervical cancer. These results suggest that the p73 G4C14-to-A4T14 SNP may function as a marker of genetic susceptibility to cervical cancer in the Chinese population.

Sci Rep 2016; 6:26526. [PMID: 27246533 PMCID: PMC4887885 DOI: 10.1038/srep26526] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2016] [Accepted: 05/04/2016] [Indexed: 12/18/2022] Open
Abstract
To analyze the relation between SNPs in DNA repair pathway-related genes and sensitivity of tumor radio-chemotherapy, 26 SNPs in 20 DNA repair genes were genotyped on 176 patients of NSCLC undertaking radio-chemotherapy treatment. In squamous cell carcinoma (SCC), as the rs2228000, rs2228001 (XPC), rs2273953 (TP73), rs2279744 (MDM2), rs2299939 (PTEN) and rs8178085, rs12334811 (DNA-PKcs) affected the sensitivity to chemotherapy, so did the rs8178085, rs12334811 to radiotherapy. Moreover rs344781, rs2273953 and rs12334811 were related with the survival time of SCC. In general, the “good” genotype GG (rs12334811) showed greater efficacy of radio-chemotherapy and MSF (24 months) on SCC. In adenocarcinoma, as the rs2699887 (PIK3), rs12334811 (DNA-PKcs) influenced the sensitivity to chemotherapy, so did the rs2299939, rs2735343 (PTEN) to radiotherapy. And rs402710, rs80270, rs2279744 and rs2909430 impacted the survival time of the adenocarcinoma patients. Both GG (rs2279744) and AG (rs2909430) showed a shorter survival time (MFS = 6). Additionally, some SNPs such as rs2228000, rs2228001 and rs344781 were found to regulate the expression of DNA repair pathway genes through eQTLs dataset analysis. These results indicate that SNPs in DNA repair pathway genes might regulate the expression and affect the DNA damage repair, and thereby impact the efficacy of radio-chemotherapy and the survival time of NSCLC.

Role of p73 Dinucleotide Polymorphism in Prostate Cancer and p73 Protein Isoform Balance. Prostate Cancer 2014; 2014:129582. [PMID: 25097786 PMCID: PMC4109114 DOI: 10.1155/2014/129582] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2014] [Revised: 05/21/2014] [Accepted: 05/22/2014] [Indexed: 12/13/2022] Open
Abstract
Background. Molecular markers for prostate cancer (PCa) risks are currently lacking. Here we address the potential association of a dinucleotide polymorphism (DNP) in exon 2 of the p73 gene with PCa risk/progression and discern any disruption of p73 protein isoforms levels in cells harboring a p73 DNP allele. Methods. We investigated the association between p73 DNP genotype and PCa risk/aggressiveness and survival by fitting logistic regression models in 1,292 incident cases and 682 controls. Results. Although we detected no association between p73 DNP and PCa risk, a significant inverse relationship between p73 DNP and PCa aggressiveness (AT/AT + GC/AT versus GC/GC, OR = 0.55, 95%Cl = 0.31–0.99) was detected. Also, p73 DNP is marginally associated with overall death (dominant model, HR = 0.76, 95%Cl = 0.57–1.00, P = 0.053) as well as PCa specific death (HR = 0.69, 95%Cl = 0.45–1.06, P = 0.09). Western blot analyses for p73 protein isoforms indicate that cells heterozygous for the p73 DNP have lower levels of ∆Np73 relative to TAp73 (P < 0.001). Conclusions. Our findings are consistent with an association between p73 DNP and low risk for PCa aggressiveness by increasing the expressed TAp73/∆Np73 protein isoform ratio.

Abstract
p73, a structural and functional homolog of p53, plays an important role in modulating cell cycle control and apoptosis. We examined whether the p73 G4C14-to-A4T14 polymorphism was related to the risk of nasopharyngeal carcinoma (NPC) among Chinese populations. The G4C14-to-A4T14 polymorphism was genotyped in 593 NPC cases and 480 controls, and in 102 NPC trios. Logistic regression analysis and transmission/disequilibrium tests (TDT) were performed to evaluate whether there was an association between the polymorphism and NPC, respectively. Functional analyses were conducted to verify the biological relevance of the polymorphism. We observed that compared with the GC/GC genotype, the genotypes containing AT allele (GC/AT + AT/AT genotypes) were associated with significantly increased susceptibility to NPC [odds ratio (OR) = 1.51; 95% confidence interval (CI) = 1.16-1.95; P = 0.002]. Furthermore, compared with the GC/GC genotype, the GC/AT + AT/AT genotypes were significantly associated with the advanced lymph node metastasis (OR = 1.47; 95% CI = 1.02-2.11; P = 0.041). A significantly greater than expected transmission of the AT allele from heterozygous parents to offspring was also observed (P = 0.049) using the TDT. By using the TdT-mediated dUPT-biotin nick end labeling assay, we observed lower apoptosis in NPC tissues from the AT allele carriers compared with that from non-carriers. Furthermore, the relative TAp73 RNA levels of the AT allele were lower than those of the GC allele in heterozygous cells. Our findings suggest that the p73 G4C14-to-A4T14 polymorphism may play a role in mediating the susceptibility to NPC in Chinese populations.
