Sparfosic acid (PALA) treatment causes apoptosis in the resistant Br1 cells.
Sparfosic acid (PALA, 300 µM) shows progressive accumulation of cells in S phase and activation of an apoptotic pathway leading to cell death.
Cell Cycle Analysis
| Cell Line: | Br-l and L-2 cell lines established from metastasis in nude mouse injected with the human tumor cell line MDA-MB-435. |
| Concentration: | 300 µM. |
| Incubation Time: | 12, 24 and 48 h. |
| Result: | Cells were predominantly in S phase in both the cell lines, although slightly higher proportion of cells in S phase were noted in L-2 than Brl-3prl cells. |
Western Blot Analysis
| Cell Line: | Br-l and L-2 cell lines. |
| Concentration: | 300 µM. |
| Incubation Time: | 4, 10 and 24 h. |
| Result: |
There was moderate difference in the level of phosphorylated Rb proteins seen in the two cell types.
Marked increase in the amount of cyclin A protein was detected in the L-2 cells undergoing apoptosis with the highest level detected at 10 h post-drug treatment. In contrast, there was no increase in the level of cyclin A seen in the Brl-3prl cells. Cyclin E protein was found elevated in the L-2 cells and Brl-3prl cells compared to their respective controls. |
