- Abstract: Aim To observe the effect of Gupi Xiaoji Decoction (GPXJY) on the structure and function of mitochondria of human hepatoma cell HepG2 cells and explore its possible mechanism. Methods CCK8 was used to detect cell proliferation, Mito-Tracker Green fluorescence staining was used to observe the mitochondrial structure, flow cytometry was used to detect the membrane potential, Elisa was used to detect the ATP content, fluoroscopic electron microscopy was used to observe the microstructure changes, and high-content screening(HCS) was used to detect the related proteins. Results Fluorescence staining showed that GPXJY damaged the mitochondria of HepG2 cells and decreased the content of ATP. The results of flow cytometry showed that GPXJY could reduce the mitochondrial membrane potential of HepG2 cells. The results of electron microscope showed that GPXJY made the mitochondria of cancer cells swell and so on. HCS found that GPXJY significantly reduced the average fluorescence intensity of Bcl-2 in HepG2 cells, and significantly increased the average fluorescence intensity of apoptosis promoting proteins Bax, cytochrome-c, caspase-3 and cleaved-caspase-3, which was statistically significant. Conclusion GPXJY can regulate the structure and function of mitochondria in HepG2 cells.
