MSA enhances the effect of paclitaxel in inhibiting cell proliferation and inducing apoptosis in MDA-MB-157 and BT-549 cells.

<p>Cells were treated with MSA, paclitaxel, or the combination for 48 hr, and then subjected to analysis for proliferation (<b>A, B</b>) or apoptosis (<b>C, D</b>). The BrdU and apoptosis readings were normalized by the SRB reading in cells set up in parallel. Error bars, SEM. *, statistically significant (<i>P</i><0.05) from the control group. **, statistically significant (<i>P</i><0.05) from both single-agent-treated sample and the control sample. Pac, paclitaxel.
