Figure 4. DAC induces autophagy in Hey cells but not in SKOv3 cells.
(A) Hey and SKOv3 ovarian cancer cells were transfected with GFP-LC3 plasmids and treated with DAC, SAHA, or a combination at their respective IC50 concentrations. Formation of punctate GFP-LC3 spots is indicative of autophagy. (B) Hey and SKOv3 cells were treated with DAC or SAHA for 1, 3, and 5 days. After staining with acridine orange, the fraction of autophagic cells was determined by flow cytometry. (C) Hey cells were treated with DAC or SAHA, or a combination for 5 days. Cells were then harvested and processed for TEM. The arrows indicate autophagosomes. N, nucleus; M, mitochondria.
