Project description:We selected normal Myodes rufocanus eyes and lens clouded eyes for transcriptome sequencing, and excavated the lens clouded eyes by analyzing and comparing. We investigated the genes and mechanisms involved in congenital cataract.
Project description:Purpose: To characterize microRNAs (miRNAs) and their possible roles in high myopia by using next generation sequencing Methods: Aqueous humor samples were obtained from 15 highly myopic eyes and 15 cataract eyes at the onset of surgery. miRNA next generation sequencing and bioinformatics analyses were performed using RNA extracted from aqueous humor samples. Results: A total of 341 miRNAs were detected in the aqueous humor samples of highly myopic eyes; 201 miRNAs were detected in the aqueous humor samples of cataractous control eyes. A total of 249 mature miRNAs and 17 novel miRNAs were differentially expressed during myopia. Possible pathways regulated by these aberrantly expressed miRNAs included the TNF, MAPK, PI3K-Akt, and HIF-1 signaling pathways. Conclusions: The current study provided an overall view of miRNA profiling in the aqueous humor of highly myopic eyes. These profiles may be associated with myopia pathogenesis, and are potential biomarkers.
Project description:Ciliary margin zone cells have differential neurogenic potential in albino and pigmented eyes. We used single cell RNA sequencing (scRNA-seq) of albino and pigmented eyes to determine transcriptomic changes underlying differential RGC genesis.
