[The effect of 20(R)-ginsenoside Rg3 on the differential expression of cell signaling genes and other related genes in human lung adenocarcinoma cell line A549].
OBJECTIVE: To study the effect of 20(R)-ginsenoside Rg3 [20(R)-Rg3] on the differential expression of cell signaling genes and other related genes in human lung adenocarcinoma cell line A549. METHODS: The cell line A549 was cultured with 20(R)-Rg3 (10(-6) mol/L) for 72 h, RNA was extracted, and the differential expression of cell signaling genes and other related genes were detected with DNA microarray. RESULTS: A total of 3 490 genes were detected, and the expression of 24 genes were changed after the addition of 20(R)-Rg3. Two cell signaling genes & transducin genes were up-regulated. Two cystoskeleton & locomotion genes were up-regulated. Three proto-oncogene & anti-oncogene genes were down-regulated. Two of the translation & synthetical genes were down-regulated, and 1 of them was up-regulated. One DNA recombination gene and one metabolism gene were down-regulated. CONCLUSION: 20(R)-Rg3 showed significant effect on the differential expression of cell signaling genes and other related genes in human lung cell line A549.
