RESUMO
Retinitis pigmentosa (RP) is the most common type of inherited retinal dystrophy. The course of RP is irreversible and leads to progressive loss of vision. It is characterized by hypotrophic degeneration of photoreceptor cells and retinal pigment epithelium. Multiple factors are involved in the development of the disease, including apoptosis, oxidative stress, and inflammatory/immune responses. In the past decades, gene therapy, stem cell therapy and other therapeutic approaches have been extensively investigated. However, due to the heritability and high heterogeneity of the disease and the difficulty in diagnosis and treatment, there is still a lack of standardized and effective therapies. Therefore, there is a need to develop new diagnostic and therapeutic approaches suitable for diseases with pathogenic mutations. With the understanding of the interaction between gene expression regulation and retinal pathology, the value of clinical applications of non-coding RNAs (ncRNAs) in retinal degeneration has gained attention. There is growing evidence that ncRNAs are widely distributed and involved in the regulation of multiple biological processes in the retina as well as processes associated with the development of RP, making them promising biomarkers for the diagnosis, treatment, and prognosis of RP. This paper reviews the crosstalk between ncRNA and RP, systematically discusses the role of ncRNAs in normal retinal cell physiology and RP pathogenesis and explores the potential of ncRNAs as therapeutic agents for clinical applications in RP.
