To determine the molecular mechanism underlying HOXA13-mediated CRC metastasis, human Cell Motility and Cancer PathwayFinder RT2 Profiler PCR Arrays were used to analyze the gene expression changes in HOXA13-overexpressing CRC cell lines (Supplementary Tables S2 and S3), since cell motility is the fundamental cellular behavior contributing to metastasis29. This evidence concerns the gene HOXA13 and colorectal carcinoma.
