Retinopathy of Prematurity (ROP), a type of
retinal neovascularization in premature infants, has become a serious problem that drastically affects the quality of life of premature infants. ROP is associated with angiogenesis and neovascularization. Here, we aimed to explain the function and latent roles of
Cytochrome P450 2J2 (
CYP2J2) in
hypoxia-induced retinopathy in
retinal vascular endothelial cells (HRVECs). HRVECs were stimulated with
hypoxia for 24 h to establish an in vitro retinopathy model. Cell viability and migration were evaluated using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium
bromide (MTT) and Transwell assays, respectively.
Protein and gene expression was determined by reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) and Western blot analysis. We observed that pcDNA3.1(+)-
CYP2J2 promoted
CYP2J2 and Jagged1 expression, while Dll4 was down-regulated in
hypoxia-stimulated HRVECs. Additionally, pcDNA3.1(+)-
CYP2J2 inhibited HRVEC viability, reduced
PCNA expression, and inhibited the migration of HRVECs. Further, the Notch pathway was inhibited in the Hypoxia+pcDNA3.1(+)-
CYP2J2 group. Opposite results were observed upon Terfenadone treatment in
hypoxia induced HRVECs. Finally, our findings further verified that
DAPT promotes the effects of
CYP2J2 on cell viability, migration, and Notch signaling in
hypoxia-induced HRVECs, while
EDTA reversed the inhibitory effects of
CYP2J2 on
hypoxia-induced HRVECs. In conclusions,
CYP2J2 was found to inhibit the viability and angiogenesis of HRVECs by inhibiting Notch signaling in a
hypoxia-induced retinopathy model.
