Three breast cancer cell (BCC)populations (ALDH cells, ALDH cells, and commercial BSCSs) are sensitive to Psoralidin treatment (10, 15, 20, and 25 μM; 24 hours) with IC50s ranging from 18 to 21 μM; however, the MCF-12A cells were resistant to Psoralidin.
Psoralidin (30 μM; 24 hours) results in a significant induction of apoptosis for ALDH cells, ALDH cells, and commercial BCSCs.
Psoralidin treatment also downregulates NOTCH1 expression in both ALDH and ALDH cells.
Cell Viability Assay
Cell Line: |
ALDH cells, ALDH cells, commercial breast cancer stem cells (BSCSs), and normal breast epithelial cells (MCF-12A) |
Concentration: |
10, 15, 50, and 25 μM |
Incubation Time: |
24 hours |
Result: |
IC50s of 18 to 21 μM for ALDH cells, ALDH cells, commercial BCSCs. |
Apoptosis Analysis
Cell Line: |
ALDH cells, ALDH cells, and commercial BCSCs |
Concentration: |
20 and 30 μM |
Incubation Time: |
24 hours |
Result: |
No significant induction of apoptosis was observed for any of the three cell types following treatment at 20 μM. However, 53.60%, 44.1%, and 45.9% of cells were apoptotic at 30 μMin ALDH cells, ALDH cells, and commercial BCSCs, respectively. |
