FGFR1 and neoplasm: Cell migration is an important process in tumor metastasis and progression.37 Several studies have reported that honokiol can inhibit the migration of various kinds of malignancies under different mechanisms.37, 38, 39 To investigate whether honokiol had a similar function in lung SCC, we performed a cell migration assay and found that honokiol could significantly inhibit the migration of H520 and SK‐MES‐1 cells, as could PD173074, which might suggest that inhibition of FGFR1 can restrict the migration of lung SCC.
