In vitro, cell apoptosis of human gastric cancer cellline SGC-7901 was observed using fluorescence staining. In vivo, a mice model was constructed to observe tumorgrowth with different doses. Cell apoptosis was examined using flow cytometry and K-RAS protein expressionusing Western blotting. The mRNA expression of P53, BCL-2, BAX, CASPASE-3, K-RAS was examined byreal-time PCR. PAMD significantly suppressed tumor growth in the xenograft model of gastric cancer in a dosedependentmanner (p<0.01). Functionally, PAMD promoted cell apoptosis of the SGC-7901 cells and significantlyincreased the rate of cell apoptosis of gastric tumor cells (p<0.05). Mechanically, PAMD inhibited the expressionof oncogenic K-RAS both at the mRNA and protein levels. In addition, PAMD affected the mRNA expression ofthe cell apoptosis-related genes (P53, BCL-2, BAX, CASPASE-3). PAMD could suppress gastric tumor growthin vivo, possibly through inhibiting oncogenic K-RAS, and induce cell apoptosis possibly by targeting the cellapoptosis-related genes of P53, BCL-2, BAX, CASPASE-3.
