Fenretinide causes phosphatidylserine translocation in Huh-7 cells but not in HepG2 cells. Huh-7 (A) and HepG2 cells (B) were treated with fenretinide and analysed for phosphatidylserine translocation by flow cytometry analysis. The percentage of cells with phosphatidylserine translocation was presented as a relative fold of DMSO treatment. Flow cytometry data were representative results from three independent experiments. Data were shown as mean ± S.E.M. (* p < 0.05, ** p < 0.01 compared with DMSO treatment).
