Poloxin inhibits proliferation. A: MDA-MB-231 cells were treated with increasing concentrations of Poloxin and harvested at indicated time points. Cell viability assays were performed by using a CellTiter-Blue assay (Promega). Cells treated with DMSO served as the control. B: Cell viability assays were also performed with human normal retinal epithelial cells (hTERT-RPE1). Cells treated with DMSO served as the control. The results are presented as the mean ± SD (n = 3) and analyzed by the Student's t-test. *P < 0.05, **P < 0.01, and ***P < 0.001.
