Exosomal miR-183-5p Shuttled by M2 Polarized Tumor-Associated Macrophage Promotes the Development of Colon Cancer Targeting THEM4 Mediated PI3K/AKT and NF-κB Pathways.

Background: Abnormal accumulation of macrophages in the colon cancer (CC) contribute to its progression. miR-183-5p has been confirmed as an oncogene in CC and this article explores the effect and mechanism of exosomal miR-183-5p enriched by M2-polarized tumor-associated macrophages (TAM) on CC cells.

Methods: The human macrophage THP1 was induced to M2 polarization through IL-4 and IL-13 treatment.
