Background: The MUC1 gene encodes glycoproteins attached to cell membrane that play a protective role in gastric cancer and protect epithelial surfaces against external factors such as Helicobacter pylori. H. pylori infection can induce a cascade of innate and acquired immune responses in gastric mucosa. Relationship between rs4072037G>A polymorphism of MUC1 gene and increased susceptibility to H. pylori infection aimed to investigate in patients with gastric cancer in Mazandaran, northern Iran.
Methods: A case-control study was conducted on 99 patients with gastric cancer (H. pylori positive and negative) and 98 controls (H. pylori positive and negative) without gastric cancer (confirmed by pathological biopsy samples obtained during endoscopy). H. pylori infection was diagnosed by histological examination using Giemsa staining. Genomic DNA extracted from peripheral blood was analyzed by PCR-RFLP technique.
Results: Analysis of all genetic models showed no significant relationship between rs4072037G>A polymorphism and risk of gastric cancer (GC). The relationship between H. pylori infection and rs4072037G>A polymorphism showed an increased susceptibility to gastric cancer in both positive and negative H. pylori groups (including case and control groups). The genetic model of GA/GG and H. pylori- positive versus GA/GG and H. pylori-negative showed a significantly increased susceptibility to gastric cancer (OR=0.251, CI: 0.128-0.493, P=0.000).
Conclusion: These findings indicate that rs4072037G>A polymorphism may interact with H. pylori infection to increase the risk of GC. |
