doi: 10.1038/s41398-020-00864-9
Figure Lengend Snippet: a Western blot showing ApoE protein level in the lysate of astrocytes treated with OGD-R and melatonin at indicated concentrations (0, 0.001, 0.1, 1, 10, and 100 nM). b CCK-8 assay showing the cell viability of co-cultured endothelial cells treated with OGD-R, melatonin (1 nM) or RAP (200 nM; n = 4). c ROS production in co-cultured endothelial cells treated with OGD-R, melatonin (1 nM), or RAP (200 nM; n = 4). d Caspase-Glo 3/7 assay showing caspase activity in co-cultured endothelial cells treated with OGD-R, melatonin (1 nM), or RAP (200 nM; n = 4). e Apoptosis rate revealed by Annexin V/PI assay in co-cultured endothelial cells treated with OGD-R, melatonin (1 nM), or RAP (200 nM; n = 4). f Western blot showing the protein levels of melatonin receptors (MT1 and MT2) in HUVEC cell or astrocytes. g CCK-8 assay showing the cell viability of endothelial cells treated with OGD-R or melatonin (1 nM; n = 4). h ROS production in endothelial cells treated with OGD-R or melatonin (1 nM; n = 4). i Apoptosis rate revealed by Annexin V/PI assay in endothelial cells treated with OGD-R or melatonin (1 nM; n = 4). j Western blot showing ApoE protein levels in the lysate and medium of astrocytes treated with melatonin (1 nM) or 666-15 (0.1 μM). k Real-time PCR showing ApoE mRNA levels in astrocytes treated with melatonin (1 nM) or 666-15 (0.1 μM). ** P < 0.01, *** P < 0.001.
