Abstract
Genetic variations of NF‐κB and its inhibitor IκB genes and their biological mechanism in oral cancer were not well recognized. The purpose of this study was to evaluate the associations of polymorphisms in NFKB1 and NFKBIA with oral cancer susceptibility, and further explore their potential mechanism in vitro. First, the polymorphisms of NFKB1 and NFKBIA were genotyped through iPLEX Sequenom MassARRAY platform in a case–control study with 425 oral cancer patients and 485 healthy controls. Then, the function was explored by a luciferase reporter assay and an electrophoretic mobility shift assay (EMSA) in human tongue squamous cell carcinoma cell lines. The results indicated that NFKB1 rs28362491 Del/Del and rs72696119 G/G genotypes were associated with the risk of oral cancer, with a strong linkage disequilibrium (D′ = 0.991, r2 = 0.971). Moreover, DG haplotype of NFKB1 also showed a significant increased risk (OR = 1.25, 95% CI: 1.02–1.53, P = 0.030). Dual‐luciferase reporter assays further revealed that the plasmids with DG or IG or DC haplotype transfected with Tca‐8113 cells or CAL‐27 cells had a lower luciferase expression than that with IC haplotype. EMSA demonstrated that 4‐bp ATTG deletion in the promoter of NFKB1 abolished the binding site of transcription factor. Our preliminary findings suggest that the haplotype of rs28362491 and rs72696119 in NFKB1 could act as a novel genetic marker to predict oral cancer risk in the southeast of China, but much more extensive researches still need to be conducted.

Functional promoter polymorphisms of NFKB1 influence susceptibility to the diffuse type of gastric cancer. Oncol Rep 2013; 30:3013-9. [PMID: 24101096 DOI: 10.3892/or.2013.2768] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2013] [Accepted: 09/04/2013] [Indexed: 01/28/2023] Open
Abstract
In the present study, we report an association between gastric cancer and polymorphisms in NFKB1 (rs28362941 and rs78696119). We employed the PCR-SSCP method to detect gene polymorphisms in 479 gastric cancer cases and 880 controls. The rs28362941 del/del homozygote was significantly associated with gastric cancer development; in particular it was closely associated with diffuse type gastric cancer. The rs78696119 GG homozygote was also associated with the diffuse type of gastric cancer. In young subjects, both polymorphisms were significantly associated with the development of gastric cancer. In addition, both polymorphisms were related to tumor progression such as tumor invasion and lymph node metastasis. The inflammatory cell infiltration into non-cancerous gastric mucosa was greater in the subjects with the rs28362491 del/del or rs78696119 GG genotype when compared to those with the other genotypes. In conclusion, functional polymorphisms of NFKB1 are associated with an increased risk of gastric cancer; in particular they are closely associated with the development of diffuse type of gastric cancer via severe gastric inflammation. These polymorphisms also appear to be associated with gastric cancer progression.
