FTI-2153, inhibits bipolar spindle formation during mitosis independently of transformation and Ras and p53 mutation status in two human lung cancer cell lines.
FTI-2153 increases the percentage of prometaphase cells with ring-like DNA morphology in transformed and non-transformed cells.
FTI-2153 (15 μM) inhibits T-24 and Calu-1 cell growth by 38 and 36%, respectively. NIH3T3, HFF and HT-1080 are less sensitive and are inhibited by only 8, 8 and 13%, respectively. A-549 and OVCAR3 cell growth is inhibited by 25 and 22%, respectively. Thus, even though T-24 and Calu-1 cells are equisensitive to FTI-2153 cell growth inhibition, FTI-2153 inhibits bipolar spindle formation only in Calu-1 cells. HFF and NIH3T3 cells are both resistant to FTI2153 growth inhibition, yet only NIH3T3 cells are resistant to FTI-2153 inhibition of bipolar spindle formation.
Cell Viability Assay
| Cell Line: | NIH3T3, HFF, HT1080, T-24, OVCAR3, A-549 and Calu-1 CELLS. |
| Concentration: | 48 h. |
| Incubation Time: | 15 μM. |
| Result: |
When A-549 cells were treated with FTI-2153 (15 μM for 48 h), the proportion of cells at prometaphase increased relative to the other phases of mitosis.
FTI-2153 accumulated cells at prometaphase with a rosette-like morphology where chromosomes form a ring surrounding a monoaster of microtubules. In all cells, except for T-24 and NIH3T3, FTI-2153 treatment increased the proportion of mitotic cells in prometaphase and decreased the percentage of cells in telophase/cytokinesis. In HT1080 cells, the percentage of cells in prometaphase and telophase/ cytokinesis were 5 and 85% in control cells and 55 and 35% in Treated cells, respectively. Similarly results were also found in HFF cells. Calu-1 and A-549 cells, as described previously, had similarly large changes, whereas OVCAR3 had smaller changes. In contrast, FTI-2153 did not significantly affect the distribution of the different phases of mitosis in T-24 and NIH3T3 cells. |
