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

<p><b>Effects of PEOL on the viability and morphology of HCT116 (A), HCT8 (B), and CCD 841 CoN cells (C)</b>. The cells (6 ×10<sup>3</sup> 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 <i>p</i> < 0.05, <i>p</i> < 0.01, <i>p</i> < 0.001 respectively as compared to untreated cells. <i>p</i> values were obtained by one-way ANOVA, followed by Fisher’s LSD test.</p>
