In cases of lung cancer, KIF4A was reported to promote cell proliferation and migration and inhibit apoptosis in LUAD cell lines, whereas KIF18B was suggested to promote LUAD cell proliferation, migration, and invasion via the Rac1/Akt/mammalian target of rapamycin (mTOR) signaling pathway [61,62]. Here, RAC1 is linked to lung carcinoma.
