Research progress on the relationship between miRNA and pathogenesis of cataract

Abstract:

The microRNA(miRNA)is a widely present small non-coding RNA(ncRNA), with a length of 20-25 nucleotides. The miRNA in eye tissue plays crucial roles in normal eyes by participating in processes such as cell growth, proliferation, differentiation, and apoptosis. Cataracts are the main cause of blindness worldwide. Research has shown that miRNA is related to the occurrence and development of cataracts, and it has new application prospects as a potential target for the treatment and prevention of cataracts. This article reviews the relationship between miRNA and the occurrence and development of cataracts through several different pathogenesis mechanisms, including oxidative damage, apoptosis, autophagy, and epithelial mesenchymal transition(EMT).
