Abstract
We analyzed gene expression patterns in human gastric cancers by using cDNA microarrays representing ≈30,300 genes. Expression of PLA2G2A, a gene previously implicated as a modifier of the ApcMin/+ (multiple intestinal neoplasia 1) mutant phenotype in the mouse, was significantly correlated with patient survival. We confirmed this observation in an independent set of patient samples by using quantitative RT-PCR. Beyond its potential diagnostic and prognostic significance, this result suggests the intriguing possibility that the activity of PLA2G2A may suppress progression or metastasis of human gastric cancer.
