Using cDNA microarray with double dots of 4096 human genes, P18 INK4C, a member of CKI, was found down-regulated in a gastric adenocarcinoma metastatic cell line (RF-48), compared with the corresponding primary cancer cell line (RF-1), which implied that P18INK4C might be involved in cell invasion and metastatic progression of human gastric adenocarcinoma. Antisense RNA expression plasmid was applied to inhibit P18 INK4C expression to study the effect of decreased P18 INK4C expression on cell migration, invasion and proliferation ability and cell cycle of RF-1. Results showed that inhibition of P18 INK4C expression could obviously enhance cell invasion ability of RF-1, but had little effect on its cell cycle and cell migration and proliferation ability. These results implied that P18INK4C might play a pivotal role in regulating cell invasion, rather than regulating cell cycle and proliferation in the progression of human gastric adenocarcinoma as expected before.
