Phenolic extract from oleaster (Olea europaea var. Sylvestris) leaves reduces colon cancer growth and induces caspase-dependent apoptosis in colon cancer cells via the mitochondrial apoptotic pathway - Fig 2

Effects of PEOL on the viability and morphology of HCT116 (A), HCT8 (B), and CCD 841 CoN cells (C). The cells (6 ×10³ cells/well) were incubated with different concentrations of PEOL for 24 h as described in Materials and Methods. Cell viability was measured by MTT test and morphology was assessed by light microscopy (magnification ×200). *,**,*** represent p < 0.05, p < 0.01, p < 0.001 respectively as compared to untreated cells. p values were obtained by one-way ANOVA, followed by Fisher’s LSD test.
