ZEB1 and neoplasm: CircAMOTL1 upregulates SIK2 by acting as a sponge of miR-526b, promotes AKT signal transduction, and induces EMT [100], circRNA-PVT1 can target EMT of cervical cancer cells induced by miR-1286 through exosomes [101], circ-HIPK3 acts as a sponge of miR-338-3p, regulates EMT mediated by HIF-1α [102], circ-ABCB10 up-regulates ZEB1 by acting as a miR-128-3p sponge [103], hsa_circ_0000730 can restrain cell proliferation, migration, and invasion in cervical cancer via miR-942-5p/PTEN axis, and it probably acts as a tumor suppressor and may be a candidate target for the treatment of CC [104].
