The mRNA level of CDKN2 (p16), retinoblastoma (Rb) and p53 in cancerous and non-cancerous tissue samples were compared using a semi-quantitative reverse-transcription-polymerase chain reaction method. The mean CDKN2 mRNA level of 10 gastric cancer specimens was significantly higher than that of their non-cancerous tissue samples (p=0.039). In contrast, the mRNA levels of Rb and p53 in gastric cancer tissues were both significantly lower than those in their noncancerous tissue samples. Furthermore, both mRNA ratios of Rb/CDKN2 and p53/CDKN2 were significantly decreased in gastric cancer tissues. Therefore, suppression of both Rb and p53 and overexpression of CDKN2 may be associated with the tumorigenesis of gastric cancer.
