Figure 2:A, B: Propolis/CAPE are cytotoxic to breast cancer cells: Cells were treated with CAPE or propolis for 24 h, 48h and 72 h. CAPE and propolis (normalized for CAPE content by Human Plasma Liquid Chromatography (HPLC) exposure results in decreased viability of MDA-231 (ER-/PR-/Her2-, TNBC), MCF-7 (ER+) and SKBR3 (Her2 +) breast cancercells in a time-dependent and concentration-dependent manner.
