The impact of O2@PL on the transfection of pTP53. A Annexin V-FITC/PI co-staining assay of MCF-7 cells after various treatments determined by flow cytometry. B Quantitative results of apoptosis rates in (A). C Western blot analysis of the P53 and HIF-1α protein expression levels in MCF-7 cells after various treatments. The proportion of P53 (D) and HIF-1α (E) relative to that in the control group are presented. All error bars are expressed as ± SD, n = 3
