Autophagic Cell Death by Poncirus trifoliata Rafin., a Traditional Oriental Medicine, in Human Oral Cancer HSC-4 Cells

Figure 6

Effects of MEPT on the viabilities of HSC-4 cells pretreated with 3-MA. HSC-4 cells were pretreated with or without 3-MA for 1 h and then 25, 50, or 100 μg/mL of MEPT for 24 h, after which cell viability was analyzed using an MTT assay. Results are expressed as the means ± standard deviations. versus the same amount of MEPT-treated cells.
