3β-Hydroxysteroid-Δ24 Reductase (DHCR24) Protects Pancreatic β Cells from Endoplasmic Reticulum Stress-Induced Apoptosis by Scavenging Excessive Intracellular Reactive Oxygen Species

Figure 5

MIN6 apoptosis induced by both cholesterol and H2O2 is inhibited by overexpression of DHCR24. MIN6 cells were exposed to cholesterol (250× dilution) and H2O2 (1 mM) 48 h postadenovirus infection. The adherent cell number was calculated as percentage of cells infected with Ad-LacZ in the control group. (); vs. Ad-LacZ.
