Fig. 3From: Antitumor activities of Aspiletrein A, a steroidal saponin from Aspidistra letreae, on non-small cell lung cancer cellsAnti-proliferative effect of AA on human lung cancer cells. H460 (a), H23 (b) and A549 (c) cells were treated with AA (0–12.5 μM) for 48 h. Cell growth was evaluated by MTT assay. The plots present the relative cell proliferation ± SEM from three independent experiments (n = 3). *, p < 0.05 vs nontreated cellsBack to article page
