25-Hydroxycholesterol protecting from cerebral ischemia-reperfusion injury through the inhibition of STING activity

25-Hydroxysterol reduces brain tissue apoptosis and oxidative damage and inflammation in mouse middle cerebral artery occlusion (MCAO) model. (A) Nissl staining 40× and 200× (scale bar = 50 μm/200 μm, N = 4 per group). (B) Western blots were used to detect the expressions of caspase-3, cleaved caspase-3, Bcl2, and Bax. (C–H) Serum levels of interleukin (IL-6), IL-1β, and tumor necrosis factor-α were detected by commercially available ELISA kits. Myeloperoxidase (MPO), malondialdehyde (MDA), and lactate dehydrogenase (LDH) levels in the serum were quantified by using commercial kits following instructions of the manufacturer. (N = 6 per group, **PPP

(CH) Serum levels of interleukin (IL-6), IL-1β, and tumor necrosis factor-α were detected by commercially available ELISA kits. Myeloperoxidase (MPO), malondialdehyde (MDA), and lactate dehydrogenase (LDH) levels in the serum were quantified by using commercial kits following instructions of the manufacturer. (N = 6 per group, **P<0.01 versus sham group, ##P<0.01, #P<0.05 versus MCAO group).
