RHO and cervical cancer: In fact, the morphology of RAB33A-overexpressing cervical cancer cells was altered, and RAB33A increased the formation of both linear and lamellar pseudopods according to phalloidin staining results (Supplementary Fig. S2a); these results indicated that Rho family members, which are involved in cytoskeletal modulation, may participate in the promotion of migration and invasion by RAB33A in cervical cancer cells.
