Overall design |
Cells were treated with increasing concentrations of drug until they were able to survive and proliferate after a pulse of cytotoxic drug. HS-TX: HS578T cells, 100 nM paclitaxel, 5 days pulse; HS-DOX: HS-578T cells, 100 nM doxorubicin, 3 days pulse; BAS-TX: BAS cells, 20 nM paclitaxe, 3 days pulse; BAS-DOX, BAS cells, 160 nM doxorubicin, 3 days pulse. For the array experiment, RNA isolated from three (drug resistant cells) or four (parental naive cells) independent cultures were used for each condition.
