Background: Lupeol, a triterpene isolated from various herbal plants, possesses an anti-inflammatory function and has been proposed as a candidate for anticancer agents. The purpose of this research was to investigate the effect of lupeol on the viability, apoptosis, cell-cycle distribution, and migration of colorectal cancer cell lines and its molecular mechanism.

Methods: Lupeol was assessed for its anticancer effect using two human colorectal cancer cell lines: SW480 and HCT116. These cells were treated with lupeol, and their viability, apoptosis, migration, and cycle distribution were detected by CCK8, flow cytometry, and the transwell method. Quantitative PCR, Western blot, and immunofluorescence were applied to detect the expressions of,,,,, and.

Results: Lupeol suppressed cell viability and migration and induced cellular apoptosis of both cell lines, with increased p53 and decreased Bcl2 protein levels (<0.05). Cell cycles of both lupeol-treated cell lines were arrested in the S phase (<0.05). Quantitative PCR and Western blot analyses showed significantly reduced expressions of,, and downstream genes of the Wnt-β-catenin pathway, including the cell-cycle-regulated genes ofandof both cell lines upon lupeol treatment (<0.05). mRNA and protein levels ofdecreased in HCT116 cells, plus the expression ofmRNA and protein decreased in SW480 cells (<0.05). Immunofluorescence analysis confirmed decreased expression of Wnt-β-catenin signaling.

Conclusion: Our findings indicate that lupeol effectively inhibits proliferation and migration and induces apoptosis and cell-cycle arrest of two colorectal cell lines by inactivation of the Wnt-β-catenin signaling pathway and downregulation of,,, and, thereby making it a promising anticancer candidate.
