چکیده
BACKGROUND Hyperactivation of nuclear factor-κB (NF-κB) is associated with various types of tumors. This study investigated the susceptibility of the rs4648068 A/G genotype in the intron region of NFKB1 to gastric cancer and the association of this polymorphism with clinicopathologic variables in gastric cancer patients. METHODS A hospital-based case-control study of 248 gastric cancer patients and 192 control individuals was conducted in Fudan University Shanghai Cancer Center (Shanghai, China). Single nucleotide polymorphism (SNP) rs4648068 genotype in NFKB1 from blood samples of a total of 440 people was analyzed by polymerase chain reaction-based genotyping. RESULTS The frequencies of the AA, AG, and GG genotypes of the rs4648068 polymorphism were 31.5%, 47.2%, and 21.3% in the gastric cancer patients and 29.7%, 59.9%, and 10.4% in the control individuals, respectively. We found that the GG genotype was associated with a significantly increased risk of gastric cancer (P = 0.042). Furthermore, among the gastric cancer cases, the rs4648068 GG genotype was associated with high clinical stage (AOR = 2.27, 95% CI: 1.11- 4.66), lymph node involvement (AOR = 2.90, 95% CI = 1.40- 6.03) and serosa invasion (AOR = 2.78, 95% CI = 1.34- 5.75). However, rs4648068 genotypes were not associated with tumor differentiation in gastric cancer patients. CONCLUSIONS Homozygous rs4648068 GG was associated with an increased risk of gastric cancer, especially for the lymph node status and serosa invasion in Han Chinese population.

The NFKB1 polymorphism (rs4648068) is associated with the cell proliferation and motility in gastric cancer
BACKGROUND We have demonstrated previously that NFKB1 single nucleotide polymorphism (SNP) rs4648068 GG homozygote was associated with the increased risk of gastric cancer in Chinese Han population. In this study, we constructed the recombinant plasmid pGL3-AA, pGL3-GG, pGL3-AA-NFKB and pGL3-GG-NFKB to investigate the function of rs4648068 by cell biology experiments. METHODS Quantitative rea...

متن کاملNuclear Factor-Kappa B1 is Associated With Gastric Cancer in a Chinese Population
Activated nuclear factor-κB (NF-κB) is associated with the pathogenesis of numerous cancers, such as gastric cancer (GC). Genetic polymorphisms in the genomic region containing nuclear factor-κB1 (NFKB1) have a plausible role in modulating the risk of GC. To identify markers contributing to the genetic susceptibility to GC, we analyzed 15 single nucleotide polymorphisms (SNPs, rs28362491, rs377...
متن کاملNo association between single nucleotide polymorphisms in pre-mirnas and the risk of gastric cancer in Chinese population
Objective(s): Accumulating evidence has demonstrated that miRNAs contribute to various genetic and epigenetic modifications in the pathogenesis of gastric cancer (GC). Recent studies focused on the four single nucleotide polymorphisms (SNPs) of pre-miRNAs including rs11614913, rs3746444, rs2910164, and rs2292832. It was suggested that these four SNPs were significantly associated with the risk ...
