Fig. 2From: Bullatacin triggers immunogenic cell death of colon cancer cells by activating endoplasmic reticulum chaperonesBullatacin induces the expression of CRT and HSP90 on the cell membrane surface in early apoptotic cells. A, B Flow cytometric analyses of the protein expression of CRT and HSP90 in SW480 and HT-29 cells treated with bullatacin for 12 h. C, D Western blot analyses of the cell membrane protein expression of CRT and HSP90 in SW480 and HT-29 cells treated with bullatacin for the indicated times. The relative protein expression of CRT and HSP90 was evaluated by quantifying the greyscale values with ImageJ. Significance: *P < 0.05 versus control, **P < 0.01 versus controlBack to article page
