FGFR2 and neoplasm: For lapatinib resistance, it has been reported that tumor suppressor miR-494 could not only reverses lapatinib resistance but also inhibit formation of cancer-initiating cells (CICs) via down-regulating expression of receptor tyrosine kinase fibroblast growth factor receptor 2 (FGFR2) in HER2-positive, FGFR2 overexpressing and lapatinib resistant YCC1-F gastric cancer cells [159].
