Overexpression of METTL3 attenuates high-glucose induced RPE cell pyroptosis by regulating miR-25-3p/PTEN/Akt signaling cascade through DGCR8

Figure 2. METTL3 affected high-glucose regulated RPE cell proliferation, apoptosis and pyroptosis. (A) Cell counting assay was employed to measure RPE cell division abilities. (B) CCK-8 assay was conducted to determine RPE cell proliferation abilities. (C, D) FCM was performed to detect RPE cell apoptosis ratio. (E) ELISA was performed to measure the expression levels of IL-1β and IL-18 in the supernatants of RPE cells. (F, G) Western Blot was used to determine the expression status of pyroptosis associated proteins (Caspase-1, Gasdermin D, NLRP3, IL-1β and IL-18) in RPE cells. (“Hg” means “High-glucose”, “OE-M” means “Overexpressed METTL3” and “KD-M” means “Knock-down of METTL3”). Each experiment had at least 3 repetitions, the data were collected and represented as Mean ± SD. “*” means p < 0.05 and “**” means p < 0.01.
