Exosome-Transmitted miR-224-5p Promotes Colorectal Cancer Cell Proliferation Targeting ULK2 in p53-Dependent Manner.

Objective: To investigate the role and molecular mechanism of exosomal miR-224-5p in colorectal cancer (CRC).

Methods: The miR-224-5p expression in CRC patient tissues and cell-derived exosomes was measured by laser capture microdissection and qRT-PCR, respectively. Dual-luciferase reporter gene assay was used to determine the target gene of miR-224-5p.
