In conclusion, circIGF1R acts a tumor suppressor in NSCLC by inhibiting the Wnt pathway through the VANGL2/miR-1270 axis, RBFOX3 promotes circIGF1R biogenesis by binding to IGF1R pre-mRNA, and is induced by paclitaxel to inhibit the migration and invasion of NSCLC cells. The gene discussed is IGF1R; the disease is neoplasm.
