Antiapoptotic and Antioxidant Properties of Orthosiphon stamineus Benth (Cat's Whiskers): Intervention in the Bcl-2-Mediated Apoptotic Pathway

Figure 3

Inhibition of hydrogen peroxide-(H₂O₂-) triggered apoptosis using ethyl acetate fraction (EAF) of O. stamineus. Epithelial cells were pretreated with or without EAF and later exposed to H₂O₂. Cells were viewed under phase contrast microscopy. (a) MDA-MB-231 control cells; (b–d) cells pre-treated with different concentrations of EAF and incubated with hydrogen peroxide; (e) cells treated with hydrogen peroxide.
