JAK1 and neoplasm: Similar to the studies of human tumors, we saw increased copy numbers of known oncogenic driver genes, including myc, egfr, crebbp, jak1, H-ras, and K-ras, as well as enrichment of pathways implicated in tumor progression, including the WNT signaling pathway, regulation of actin cytoskeleton, focal adhesion, cell shape, and mobility proteins.
