Abstract

This research aims to study the effect of magnetic nanoparticles of Fe3O4 (MNP Fe3O4) containing gambogic acid (GA-MNP Fe3O4) on colorectal cancer (CRC). MNP Fe3O4 enhanced the antitumor effect of GA by inhibiting the malignant behavior of CRC cells. RORB was a target of GA, and GA activated RORB expression to inhibit metastasis of CRC. Knockdown of RORB impaired the effect of GA-MNP Fe3O4 on CRC metastasis. EMILIN1 was a target of RORB, and RORB promoted transcription of EMILIN1. Overexpression of EMILIN1 reversed the effect of knockdown of RORB on GA-MNP Fe3O4 and inhibited metastasis in CRC. These findings revealed that MNP Fe3O4 enhanced the antitumor effect of GA and activated RORB to promote EMILIN1 transcription and inhibit CRC metastasis.
