Fig. 7. LY379196 potentiates the effect of paclitaxel and vincristine on the suppression of the number of viable neuroblastoma cells. SK-N-BE(2) cells were cultured for 3 days in regular growth medium with increasing concentrations of paclitaxel (A) or vincristine (B) in the absence ({circ}) or presence (•) of 100 nM LY379196. The viable cell number was analyzed with a MTT assay, and data (mean ± SE; n = 6) are expressed as a percentage of the values obtained in the absence of drugs.
