Nicotinic receptors modulate antitumor therapy response in triple negative breast cancer cells

Figure 4 Sensitivity of MDA-MB-231 cells to chemotherapy. Concentration-response curves of paclitaxel (PX) on the viability of surviving cells after three cycles of PX treatment (10^-7 mol/L) in the absence or presence of nicotine (10^-10 mol/L). Values are the mean ± SD of three experiments performed in duplicate. ^bP < 0.01; ^cP < 0.001 vs surviving cells after three cycles of PX treatment. PX: Paclitaxel; NIC: Nicotine.
