BSO@HAuNS induce cell death in mitochondrial-dependent pathway. A549 cells were exposed to various treatments for 72 h, then harvested, and washed twice with PBS. (a) After treatment, the cells were processed by JC-1 staining and measured by flow cytometry. Mitochondrial membrane potential changes were quantified by fluorescence shift (red to green) of samples. (b) Following exposure to BSO, PEG-SH-HAuNS, and BSO@HAuNS, the Fluo-4-dependent fluorescence of the different samples was indicated by flow cytometry. Numbers depict the effect of BSO@HAuNS on A549 cytosolic Ca2+ concentration. Data shown are means (±SD, ). (c) Caspase-3 activity after BSO-loaded PEG-SH-HAuNS treatment for 72 h was determined with cleaved caspase-3 (Asp175) antibody (Alexa fluor 488 conjugate) by flow cytometry. and compared with control.
