Figure 2From: Antiproliferation and cell apoptosis inducing bioactivities of constituents from Dysosma versipellis in PC3 and Bcap-37 cell lines Effect of PTO on proliferation of tumor cells. After PC3, Bcap-37, BGC-823 and NIT3T3 cells were treated with PTO for 72 h in the concentrations varied from 2.5 to 60 μ M, growth inhibition of those tumor cells was detected by MTT assay. Data are presented as means ± SD, n = 4.Back to article page
