Anti-proliferative activity of PSS and PL on 4 breast cancer cell lines. Cisplatin was used as a positive control. BrdU colorimetric assay was tested 72-h post treatment, the percentage cell proliferation was plotted in % of control compared between the untreated cells and each treatment group. A MCF7, B T47D, C MDA-MB-231, and D MDA-MB-468. Data represented as mean ± SE (n = 5) where ^*, ^**, ^***, ^**** represented P ≤ 0.05, P ≤ 0.01, P ≤ 0.001, and P ≤ 0.0001 from statistical analysis using Unpaired t-test compared between the untreated cells among the same group
