Given that DAB2IP is a protein in the RAS–GTPase family26 and acts as a tumor suppressor for different kinds of tumors41, such data indicated that miR-328-5p targeted DAB2IP mRNA to attenuate its expression, together with decreased circRNA-5692 expression to reduce its sponging activity, and promoted the progression of HCC. Here, DAB2IP is linked to neoplasm.
