Further genes identified as targets of miR-138 in NSCLC tissues and cell lines are: 3-phosphoinositide-dependent protein kinase-1 (PDK1) [41], forkhead box P4 (FOXP4) [42], G-protein-coupled receptor kinase-interacting protein 1 (GIT1) and semaphoring 4C (SEMA4C) [43], yes-associated protein 1 (YAP1) [44], and LIM domain kinase (LIMK1) [45]. The gene discussed is FOXP4; the disease is non-small cell lung carcinoma.
