Abstract
Over the last few decades, the number of people diagnosed with cancer has increased dramatically every year, making it a major cause of mortality today. Colon cancer is the third most common cancer worldwide, and the second in mortality rate. Current cancer treatment fails to treat colon cancer completely due to the remains of Cancer Stem Cells (CSCs). Morin flavonoid present in figs (Ficus carica) and other plant sources, was found to have an anti-proliferative effect on the colon cancer model and cell line, but it is not studied for its effect on the colon CSCs. In this study, we have tested the potency of morin to inhibit CSCs. We found that morin has significantly reduced colon cancer cell proliferation, colony formation, migration, and colonospheroid formation in a dose-dependent manner. Pumilio-1 (PUM1) has been shown to play an important role in colon CSCs maintenance. We found that morin has a good binding affinity with PUM1 protein with one hydrophobic and two hydrogen bond interactions. Further, the immunofluorescence results have also shown a reduction in PUM1 expression in colon cancer cell lines after morin treatment. CD133 is overexpressed in colon CSCs and morin treatment has reduced the CD133 expression in HCT116 and CT26 colon cancer cell lines. Our research outcome has explored the anti-cancer stem cell potency of morin via targeting the PUM1 protein and further reducing the colon spheroids formation and reducing the CD133 expression in colon cancer cells.
