New anti-proliferative agent, MK615, from Japanese apricot “Prunus mume” induces striking autophagy in colon cancer cells in vitro

Figure 6 Immunofluorescence staining with Atg8 (LC3). SW480 (A), COLO (B) and WiDr (C) cells were cultured with MK615 at 300 μg/mL for 6 h. Nuclei were stained with DAPI (A, C and E), and Atg8 (LC3) was localized in the cytoplasm (B, D and F; note the central blank area in the cells).
