This indicates that the formation of an amplicon, in which both the GAS and the ERBB2 genes are amplified, might be unique in gastric cancer, especially in its intestinal type, and that simultaneous amplification of both genes is important to the tumorigenesis of intestinal gastric cancer.

To explore the interaction models of the cytochrome P-450 (CYP) 1A1 Val variant and glutathione S-transferase (GST) M1 null polymorphisms with tobacco smoking in the occurrence of intestinal gastric cancer.

By the methods of frozen tissue array-based immunohistochemistry, Western blot analysis and RT-PCR, a paralleled study was conducted to check Wnt2 expression and beta-catenin intracellular distribution in two major subtypes of gastric cancers (intestinal gastric cancer, i-GC and diffuse gastric cancer, d-GC) and their premalignant (intestinal metaplasia, IM and chronic gastritis, CG) and noncancerous counterparts.

An increased risk for gastric cancer was found to be associated with the inheritance of the p73 homozygous variant genotype among the gastric cancer intestinal histotype (odds ratio (OR)=6.75; 95% confidence interval (95% CI)=1.88-24.24).

In the meta-analysis, TP53 72Pro was associated with increased risk of diffuse gastric cancer among Asians (OR, 1.44; 95% CI, 1.04-1.99), but decreased risk of intestinal gastric cancer among Caucasians (OR, 0.56; 95% CI, 0.36-0.89).
Although an association with p27(KIP1) and H. pylori strain was found in the intestinal gastric cancer subtype, negativity for p27(KIP1) and C-MYC markers was the most frequent cluster, followed by cluster II, and both were present, independent of the H. pylori genotype.

IHC showed that periglandular POSTN deposition, comprising linear deposition abutting the glandular epithelial cells in normal mucosa, disappeared during intestinal gastric cancer progression.
These findings indicate that potentially functional TGF-α gene variant may contribute to the risk of intestinal gastric cancer and/or gastric noncardia cancer and could be used as molecular markers for detecting intestinal gastric cancer and/or gastric noncardia cancer in Chinese Han population.
