Apoptosis/necrosis assays performed in HCT116 cells at 24 h after the treatments. a–d Representative confocal laser scanning microscopy images of the cells after different treatments as indicated. The concentration of TPP-Lipo-VP-10Au used to treat the cells was 250 µM. Scale bar is 70 µm. e Relative changes in levels of apoptosis and necrosis upon different treatments as indicated in a–d. f Relative protein expression was analysed by using ImageJ software. Protein expression was normalized by use of the loading control protein (β-actin)
