Abstract
- This study aimed to clarify the regulation role of miR-708 and miR-335-3p in retinal ganglion cell (RGC) autophagy and apoptosis in glaucoma. Chronic glaucoma mice were established by laser photocoagulation. RGCs were isolated and transfected with a series of plasmids and the cultured in 60 mmHg pressure. miR-335-3p, miR-708, and ATG3 mRNA expressions were detected by qRT-PCR. Protein levels of ATG3, autophagy-related protein LC3, and p62 were detected by Western blot. The apoptosis of RGCs was detected by flow cytometry. The regulation role of miR-335-3p/miR-708 in ATG3 was confirmed by the dual-luciferase reporter gene. The expressions of several miRNAs were measured in retinal tissues from chronic glaucoma mice and RGCs under pressure conditions, and results showed that both miR-335-3p and miR-708 were down-regulated. Besides, the inhibition of miR-708 and miR-335-3p induced the apoptosis of RGCs through promoting autophagy. Also, miR-708 and miR-335-3p could bind to ATG3 and targeted regulated ATG3. Furthermore, the interference with miR-708/miR-335-3p induced RGC apoptosis by up-regulating ATG3 to promote autophagy. In general, the down-regulation of miR-708 and miR-335-3p contributed to the apoptosis of RGCs through promoting autophagy in glaucoma.
