Differences in K-ras and p53 gene mutations among pancreatic adenocarcinomas associated with regional environmental pollution

Abstract

Our study reveals that there are differences in the frequencies and types of K-ras and p53 mutations found in pancreatic adenocarcinomas of patients in high-pollution and low-pollution regions in Egypt and suggests that environmental factors may explain these differences. We speculate that gene-environment interactions in pancreatic carcinogenesis also occur in other populations.
