Propidium iodide uptake was measured by flow cytometry to assess cell death. After treatment, cells were stained with 1 μg·mL−1 PI (Invitrogen, Eugene, OR, USA) for 30 min at room temperature in the dark. PI uptake was quantified with a FACSCalibur Flow Cytometer (BD Biosciences, San Jose, CA, USA).
