Colorectal cancer (CRC) is a commonly diagnosed type of cancer globally. The molecular mechanism by which peiminine suppressed the progression of CRC is not fully addressed. The viability was assessed through cell counting kit 8 assay. Colony formation assay was used to analyze the colony formation ability. The metastasis was evaluated by transwell migration and invasion assays. Quantitative real-time PCR was performed to measure the expression of LINC00659 and miR-760 in CRC cells. The binding sites between miR-760 and LINC00659 were predicted by Starbase software and verified by dual-luciferase reporter assay, RNA immunoprecipitation assay and RNA-pull down assay. The in-vivo function of peiminine in CRC progression was confirmed by murine xenograft model. Peiminine inhibited the viability, colony formation and metastasis of CRC cells. Peiminine notably down-regulated the expression of LINC00659, while the expression of miR-760 was up-regulated by peiminine treatment. MiR-760 was a direct target of LINC00659 in CRC cells. The depletion of miR-760 attenuated the inhibitory effects of LINC00659 intervention on the viability, colony formation and metastasis of CRC cells. Peiminine restrained the progression of CRC through LINC00659 and miR-760. LINC00659 inhibited the growth of CRC tumors through LINC00659/miR-760 axis in vivo. Peiminine suppressed the development of CRC through inhibiting the viability, colony formation and metastasis of CRC cells via LINC00659/miR-760 axis. LINC00659/miR-760 axis might be an underlying target for CRC therapy.
