Furthermore, the functional experiments revealed that the overexpression of miR-30a-5p inhibited the PC cell proliferation, invasion and EMT process, while reintroduction of RAB11A partially weakened suppressive effects of miR-30a-5p overexpression, which suggested that miR-30a-5p inhibited PC tumor development through targeting RAB11A. Here, RAB11A is linked to neoplasm.
