The microarray data were then analyzed by the Parametric Gene Set Enrichment Analysis (PGSEA) package of a bioconductor program to get enriched gene sets for the mice of 5-FU-induced OM, and we found Bglap-rs1 and Chi3l4 were significantly down-regulated (–12.69-fold and −6.35-fold when compared with the control group, respectively). This evidence concerns the gene BGLAP and ocular melanoma.
