Combined analysis showed that subjects carrying the miR-34b/c rs4938723 CT/CC and TP53 CG/CC genotypes had a 0.62-fold decreased risk to develop gastric cancer compared with subjects carrying the miR-34b/c rs4938723 TT and TP53 CG/CC genotypes (OR=0.62; 95% CI, 0.40-0.96).
Based on the functional interaction between p53 and p73 in carcinogenesis, we investigated the combined effect of p73 G4C14-to-A4T14 and p53 gene polymorphisms and their interaction with selected environmental factors, on the risk for gastric cancer in a hospital-based case-control study conducted in Italy.
In our area, in which a high rate of familial aggregation was demonstrated, the lack of germ line mutation of TP53 together with the infrequency of mutation of E-cadherin gene seem to limit the role of genetic predisposition in the development of gastric cancer.
We conclude that the prevalence of mutations of p53 in our series is similar to what has recently been observed in other cases of gastric cancer, but lower than in colon carcinomas.
In conclusion, this study revealed that p53 codon 72 polymorphism and dietary and tobacco habit interactions influence stomach cancer development in Mizoram, India.
In this study, we used sequencing analysis to investigate the STK11, CDH1, and TP53 loci for a germline mutation in two siblings with PJS with primary GC.
The fact that p53 mutations were significantly correlated with poor survival of patients after potentially curative resection of gastric cancer may have clinical implications for multimodal therapies.
ENE was present in 36% of patients.EBV-positive carcinoma was evident in 5.8%, and p53 aberrant (chromosomal instable) tumors in 22.2%, a gastric cancer with deficient mismatch-repair status in 9%, and MSS/p53neg/EBVneg tumors were seen in 63% of patients.
TP53 mutation p.R337H in gastric cancer tissues of a 12-year-old male child: evidence for chimerism involving a common mutant founder haplotype: case report.
The molecular subtypes combining the CIMP and TP53 hot spot mutation status provide distinct clinicopathological features and prognostic impacts in GC.
Early-onset gastric cancer seems to be a component of Li-Fraumeni syndrome, suggesting the need for early and regular endoscopic screening in individuals with germline TP53 mutations, particularly among those with a family history of gastric cancer.
The purpose of the present hospital-based case-control study was to investigate the association between the miR-34b/c rs4938723 and TP53Arg72Pro polymorphisms and the risk of gastric cancer.
While the results suggest that the p53 codon 72 polymorphism may contribute to gastric cancer susceptibility, further larger studies are needed to substantiate our findings and to explore a possible interaction between p53 codon 72 polymorphism and alcohol in the etiology of gastric cancer.
The Pro/Pro genotype of the p53 codon 72 polymorphism carries a higher risk for gastric cancer in general and is also associated with a much higher risk for EGC than AGC.
Our data suggest that GC with TP53 mutations seems to develop as differentiated histologic type and show aggressive biological behavior such as venous invasion.
In this study, we extended these observations to explore the combination effect of adenoviral vector carrying wild type p53 (Ad-p53) gene therapy with a HDACI, sodium butyrate (SB), on xenografted human gastric cancer cells (KATO-III) and hepatocellular carcinoma cells (HuH7) in nude mice.
