Figure 7. Melatonin inhibited NOTCH3 and p65 gene expression in different groups. Pericytes in the Transwell were pretreated with IL-1β (10 ng/mL) for 24 h in serum-free medium with or without pretreatment with DAPT (10 μmol/L), PDTC (25 μmol/L l) and WB-3CT (20 μmol/L), and in combination with melatonin (MEL, 10 μmol/L) for 30 min. (A–C) NOTCH3 mRNA levels were quantified in IL-1β-treated, IL-1β + DAPT/PDTC/SB-3CT, and IL-1β + DAPT/PDTC/SB-3CT + MEL groups compared with the control group. qRT-PCR data were normalized to GAPDH expression. (D–F) p65 mRNA levels were quantified in IL-1β-treated, IL-1β + DAPT/PDTC/SB-3CT, and IL-1β + DAPT/PDTC/SB-3CT + MEL groups compared with the control group. Results are presented as the mean ± SD, n = 3. ^*p < 0.01 compared with the control; ^#p < 0.01 compared with the IL-1β-treated group; ^##p < 0.01 compared with the IL-1β + DAPT group; ^$p < 0.01 compared with the IL-1β + PDTC group; ^&p < 0.01 compared with the IL-1β + SB-3CT group.
