Figure 3. In contrast with high doses, low dose PTX did not affect cell proliferation, viability, and apoptosis of EGI-1 cells.
A–C. Effects of low dose PTX (1.5, 15nM) on cell proliferation (BRDU incorporation, A), viability (MTS assay, B), and apoptosis (CC3 immunofluorescence, C) were evaluated in EGI-1 and compared with effects of higher doses (150, 1500nM) and with untreated cells. In contrast with the highest doses, these cell activities were not affected by low dose PTX (n=6 in all experiments). **p<0.01 vs Ctrl.
