Abstract

Tumor dissemination and invasive behavior are associated with a majority of cancer-related mortality cases. Loss of E-cadherin, which is caused by several tumor-promoting factors, is associated with metastasis and poor prognosis in many neoplasms. In this study, we aimed to identify small molecule compounds that restore the expression of E-cadherin, because these molecules are most likely to suppress tumor malignancy by restoring E-cadherin function and/or by inhibiting signals that suppress E-cadherin expression. Here, we developed a fluorescence screen system based on E-cadherin expression. A pilot drug library screen revealed that methotrexate (MTX) strongly induces E-cadherin expression in a colorectal cancer cell line, SW620. From the screen for 9600 compounds, we identified 9 hit compounds, which restored the expression of E-cadherin in SW620 and/or a melanoma cell line, SK-MEL-28. We confirmed that MTX and the other identified compounds transcriptionally promote E-cadherin expression. Among these, 2 compounds suppressed migration/invasion capacity in colorectal cancer cells and 3 in melanoma cells. A compound reduced SW620 migration and invasion with subtle effects on cell viability in SW620, SK-MEL-28, and a non-tumor cell line, HaCaT, with decrease in AKT and ERK1/2 protein levels. One of the other compounds reduced SK-MEL-28 cell migration and invasion and affected the viability only of SW620 and SK-MEL-28 cells but not HaCaT cells. These results suggest that these compounds would be attractive lead molecules as anti-metastasis agents.
