Apoptosis assay (i) Plot and Graph denoting annexin V/PI staining used to monitor cells (FITC + PI +) are shown in Q3 and Q2 quadrant, respectively (ii) The percentage of early apoptotic cells. Data are representative of three experiments expressed as mean ± SD (n = 3). *P < 0.05, **P < 0.01, ***P < 0.001 when PSO-NE treated cells compared with control cells using unpaired t-test.
