AXL tyrosine kinase promotes tumor progression through serine/threonine protein kinase (AKT)/GSK-3β/β-catenin signaling, β-catenin nuclear-translocation-induced snail family transcriptional repressor 1 (SNAIL) transcription, and activation of MMP-2 and MMP-9 [120]. The gene discussed is MMP2; the disease is neoplasm.
