Plant-derived compounds and/or extracts have proven to be beneficial for the treatment of a broad spectrum of cancers with minimal side effects. In this study, we investigated whether a crude acetone extract of Momordica balsamina (MBE) can interfere with the metastatic ability of HT-29 colorectal cancer (CRC) cells. The phytochemical composition of MBE was determined by ultra-performance liquid chromatography and cytotoxic effects by the MTT and acridine orange/ethidium bromide staining assays. The effect of MBE on the formation of reactive oxygen species was assessed using the DCFH2 -DA assay. Wound healing assay, transwell cell invasion assay, cell adhesion assay, and the extracellular matrix-cell adhesion array were used to assess the antimetastatic effects of MBE. The effect of MBE on the expression of TNF-α, NF-κB, TIMP-3, MMP-2, and MMP-9 was assessed by western blot analysis. Our results showed that MBE consists of a mixture of compounds without a known anticancer activity in CRC and exhibits cytotoxicity against HT-29 cells. MBE also suppressed reactive oxygen species formation, cell invasion, cell migration, and cell adhesion. The reduction of cell invasion was associated with the downregulation of TNF-α, NF-κB, MMP2, and MMP9 and upregulation of TIMP-3 proteins. We concluded that MBE inhibits the metastatic ability of HT-29 CRC cells in vitro.
