Effect of methanol extract of triphala (MET) on pro- and antiapoptotic protein, Bax, and Bcl-2 expression. HCCSCs were treated with MET (104 μg/mL) and 5-fluorouracil (75 μg/mL). Cytoplasmic proteins were extracted by using ...
3.6. Methanol Extract of Triphala Suppresses the Stemness of HCCSCs and Suppressed c-Myc and Cyclin D1 Proteins
The stemness (self-renewal) of HCCSCs treated with 25, 50, 100, or 200 μg/mL of MET for 24 hours was evaluated using the colony-forming assay [35]. Our results demonstrated that suppression of colony formation by MET was dose-dependent (Figure 6). MET completely inhibited the formation of colonies at 200 μg/mL. To understand the effect of triphala extract on stemness, we measured expression of c-Myc and cyclin D1, the key target genes of Wnt pathway using western blotting. We observed a significant decrease in the expression of c-Myc and cyclin D in the nucleus (p < 0.05) (Figure 7). This may explain how triphala extract suppresses colon cancer stem cell proliferation and colony formation ability.
