Project description:Early changes in the transcriptome associated with lens wounding in an ex vivo post-cataract surgery chicken model. Here we report the changes in the transcriptome that occur 1hr vs. time 0 post-cataract surgery wounding. Our data provide a molecular framework for understanding the early gene changes associated with the injury response of the lens.
Project description:Cataract surgery is the most commonly performed ophthalmic procedure worldwide, yet the long-term molecular adaptations of lens epithelial cells (LECs) following surgery remain poorly understood. In this study, we conducted bulk RNA sequencing on lens capsules from 34 human donors, including 17 with an average of 7 years post-cataract surgery and 17 non-cataract controls. Differential expression analysis revealed substantial transcriptional changes in post-surgical LECs, including 1,690 upregulated and 579 downregulated genes. Gene Set Enrichment Analysis (GSEA) and Gene Ontology (GO) analyses identified activation of oxidative stress response, cell survival pathways, and immune response signatures. Collectively, our findings reveal that LECs undergo profound and sustained molecular reprogramming following cataract surgery, including inflammatory, fibrotic, migratory, and senescent changes. These adaptations may contribute to posterior capsule opacification (PCO) and highlight potential therapeutic targets for its prevention.
Project description:RNAseq analysis was used to determine the transcriptomic changes associated with regenerative vs. fibrotic repair to lens injury. Using an ex vivo post-cataract surgery model, we can follow two distinct outcomes to lens injury: 1) A regenerative wound healing response that ensues across the cell-denuded lens capsule basement membrane (BM), culminating in wound closure on Day 3 (D3) post-injury. 2) Induction of fibrosis, which occurs when a wound healing response occurs off the lens capsule, termed the extracapsular zone (ECZ), where transition to a fibrotic phenotype occurs on day 3 post-injury. Here, we report the changes in the transcriptome that occur on D1, D2, and D3 post-injury, a period that covers wound healing across the BM and time points prior to (D1, D2) and after induction of the fibrotic phenotype (D3). Our data provides a molecular map for understanding the gene changes associated with navigating normal and pathological outcomes to lens injury.
