From: The cytotoxic effect of Baeckea frustescens extracts in eliminating hypoxic breast cancer cells
Effects of B. frutescens leaves extracts on MCF-7 cell viability in hypoxic condition. Cytotoxicity was determined using cell viability assay and the IC50 value calculated as half maximal percentage of cell viability inhibition is indicated by the red horizontal line. Hypoxic condition was induced in MCF-7 cells with 2.0 mM of DMOG and incubated with either (a) hexane, (b) L90, (c) L70,(d) L50 or (e) water extract of B. frutescens leaves or (f) etoposide, which served as positive control for 48 (left panels) or 72 (right panels) hours. Data is expressed as mean ± standard error mean based on six independent experiments with triplicate wells for each concentration
