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 () 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.
