Effect of GD on mitochondrial homeostasis of human lung cells.
(a) Flow cytometry based JC-1 assay showed a significant reduction in MMP of A549 and BEAS-2B cells after 24 h exposure of GO, TRGO and CRGO. (b) Representative TEM photomicrographs also showed the damage to mitochondrial cristae structure in both cells. Data is mean ± SE of three independent experiment. *p < 0.05, **p < 0.01, compared to control value.
