Sirtuin 1 alleviates endoplasmic reticulum stress-mediated apoptosis of intestinal epithelial cells in ulcerative colitis

Figure 3 Sirtuin 1 inhibits Caco-2 apoptosis. A: Cells in the upper-right (UR) portion are late apoptotic cells, whereas cells in the lower-left and lower-right (LR) portions are viable and early apoptotic cells, respectively; B: Apoptotic rate (UR + LR) of Caco-2 cells. Each value is presented as the mean ± SD. ^cP < 0.001 vs UC. UC: Ulcerative colitis; NAM: Nicotinamide.
