| Research Abstract |
Epigenetic silencing of genes by aberrant DNA methylation is recognized as a crucial component of the mechanism underlying tumorigenesis. We examined the methylation statuses of six tumor-related genes in 106 primary gastric carcinomas by methylation-specific PCR and compared them with the past lifestyles of the patients. Significant association was found between a decreased intake of green tea and methylation of CDX2 and BMP-2. More physical activity was correlated with a lower methylation frequency of CACNA2D3. Thus, some epidemiological factors, such as green tea intake, could be important as to determination of the methylation statuses of selected genes and may influence the development of cancer, including that of the stomach.
