Figure 3From: Cephalotaxus griffithii Hook.f. needle extract induces cell cycle arrest, apoptosis and suppression of hTERT and hTR expression on human breast cancer cells CGN PE extract induces cell cycle arrest in human breast cancer cells. ZR751 cells were treated with (5, 10 and 20 μg/ml) or without PE extract for 24 h prior to cell cycle analysis. Each bar represents the mean ± SD (n = 3). Data denoted ***(P < 0.001) are significant compared to controls, as analysed by t-test.Back to article page
