Fibroblast growth factor receptor-3 (FGFR3) is a receptor tyrosine kinase implicated in the tumorigenesis of multiple malignancies, including bladder and other urothelial cancers, multiple myeloma, and cervical cancer.
The research conducted in this article examines a frequently identified fusion protein between FGFR3 and transforming acidic coiled-coil containing protein 3 (TACC3), frequently identified in glioblastoma, lung cancer, bladder cancer, oral cancer, head and neck squamous cell carcinoma, gallbladder cancer, and cervical cancer.
In this report, we aimed to explore the roles of gene polymorphisms affecting x-ray repair cross complementing 1 (XRCC1), the tumor protein p53 (TP53), and fibroblast growth factor receptor 3 (FGFR3) in the context of susceptibility to cervical cancer.
These results indicate that HLA-DPB1*1301 may confer susceptibility to cervical cancer, and the haplotypes DRB1*150101-DQB1*0602 and DRB1*070101-DQB1*0201 may contribute to the resistance to the development of cervical cancer among Chinese women.
Additionally, as for the HPV16 E6 prototype-positive cervical cancers, a significant positive association was found in DQB1*060101 allele (OR=5.95; P=0.002; Pc=0.036), and similar trends were observed for DQB1*030201 (OR=10.87, P<0.0001; Pc=0.0018), and DPB1*1301(OR=7.40, P=0.002; Pc=0.04).
Our study provides the first systematic investigation of the association of genetic variants in the HLA-DP region with cervical cancer susceptibility and provides further insight into the contribution of polymorphisms in the HLA-DP region to risk of cervical cancer.
D6S2766 and D6S2764, which are located near to the region containing the HLA-DPB genes, were negatively related with cervical cancer (OR for the D6S2766-195 allele carriers = 0.50), and positively related with cervical cancer (OR for the D6S2764-209 allele carriers = 2.44), respectively.
Subgroup analyses based on race system showed that HLA-DPB1⁎13:01 was significantly associated with an increased risk of cervical cancer in Asia (OR=1.834, 95%CI: 1.107-3.039, Pz=0.019).
The results illustrate the value of pathway-based analysis to mine genome-wide data, and point to the importance of the MHC region and specifically the HLA-DPB1 locus for susceptibility to cervical cancer.
Mutations in the tumor suppressor gene LKB1 are important in hereditary Peutz-Jeghers syndrome, as well as in sporadic cancers including lung and cervical cancer.
The liver kinase B1 (LKB1) gene is a tumor suppressor associated with the hereditary Peutz-Jeghers syndrome and frequently mutated in non-small cell lung cancer and in cervical cancer.
The LKB1 serine-threonine kinase is a tumor suppressor that is inactivated in a large number of sporadic human lung non-small cell carcinomas (NSCLCs) and cervical cancers.
These suggest that overexpressions of MMP-2 and MT1-MMP, loss of TIMP-2 expression, and up-regulation of beta-catenin by AAC-11 transfection may contribute to the development of cervical cancer invasion.
