Reference title
Long non-coding RNA MEG3 promotes cataractogenesis by upregulating TP53INP1 expression in age-related cataract.
Experimental verification
qRT-PCR;luciferase reporter assays;Western blot
Functional description
Knockdown of MEG3 increased the viability and inhibited the apoptosis of LECs upon the oxidative stress induced by H2O2. MEG3 was localized in both nucleus and cytoplasm in LECs. MEG3 facilitated TP53INP1 expression via acting as miR-223 sponge and promoting P53 expression. Additionally, TP53INP1 knockdown alleviated H2O2-induced lens turbidity. In summary, MEG3 promoted ARC progression by up-regulating TP53INP1 expression through suppressing miR-223 and promoting P53 expression, which would provide a novel insight into the pathogenesis of ARC.
