From: Controlled delivery of BID protein fused with TAT peptide sensitizes cancer cells to apoptosis
Effect of TAT-BID on apoptosis induced in PC3 cells by TRAIL. PC3 cells were incubated with TAT-BID (30 μg/ml) and TRAIL (200 ng/ml) for 24 h. A. Percentage of apoptotic cells detected by flow cytometry. The average of number of apoptotic cells (±SD) was shown. B-E. Representative cytograms. F-I. Microscopic pictures of the cells. Cells were stained with Giemsa and May-Grünwald dyes. B, F. Control cells. C, G. Cells treated with TAT-BID. D, H. Cells treated with TRAIL. E, I. Cells treated with TAT-BID and TRAIL.
