Effects of DHA on myocardial mitochondria in the LPS-induced HL-1 cardiac cells. A) Representative TEM images of HL-1 cells in control, DHA-treated, LPS-treated, and DHA + LPS-treated cells (scale bar = 1 μm). Black arrows indicate normal mitochondria, red arrows indicate abnormal mitochondria. B) Representative fluorescence images of JC-1 staining show the change in high mitochondrial membrane potential (red) and low mitochondrial membrane potential (green), which is used to evaluate mitochondrial damage. LPS treatment increased green fluorescence, whereas DHA decreased green fluorescence (scale bar = 20 μm).
