While transcriptomic and machine learning (ML) approaches have elucidated fibrosis-related pathways in other tissues, the molecular divergence between regenerative and fibrotic outcomes in the lens remains unclear. Here, we used an ex vivo chick lens injury model to simulate post-surgical conditions, collecting RNA from lenses undergoing either regenerative wound healing or fibrosis between days 1\u20133 post-injury. Bulk RNA sequencing data were normalized, log-transformed, and subjected to univariate filtering prior to training LASSO, SVM, and RF ML models to identify discriminatory gene signatures. Each model was independently validated using a held-out test set. Distinct gene sets were identified, including fibrosis-associated genes (VGLL3, CEBPD, MXRA7, LMNA, gga-miR-143, RF00072) and wound-healing-associated genes (HS3ST2, ID1), with several achieving perfect classification. Gene Set Enrichment Analysis revealed divergent pathway activation, including extracellular matrix remodeling, DNA replication, and spliceosome associated with fibrosis. RT-PCR in independent explants confirmed key differential expression levels. These findings demonstrate the utility of supervised ML for discovering lens-specific fibrotic and regenerative gene features and nominate biomarkers for targeted intervention to mitigate PCO.<\/jats:p>","DOI":"10.3390\/ijms26157422","type":"journal-article","created":{"date-parts":[[2025,8,5]],"date-time":"2025-08-05T15:56:16Z","timestamp":1754409376000},"page":"7422","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Supervised Machine-Based Learning and Computational Analysis to Reveal Unique Molecular Signatures Associated with Wound Healing and Fibrotic Outcomes to Lens Injury"],"prefix":"10.3390","volume":"26","author":[{"given":"Catherine","family":"Lalman","sequence":"first","affiliation":[{"name":"Department of Pathology and Genomic Medicine, Thomas Jefferson University, Philadelphia, PA 19107, USA"},{"name":"Sidney Kimmel Medical School, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kylie R.","family":"Stabler","sequence":"additional","affiliation":[{"name":"Department of Pathology and Genomic Medicine, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yimin","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, Western University, London, ON N6A 3K7, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8374-0551","authenticated-orcid":false,"given":"Janice L.","family":"Walker","sequence":"additional","affiliation":[{"name":"Department of Pathology and Genomic Medicine, Thomas Jefferson University, Philadelphia, PA 19107, USA"},{"name":"Sidney Kimmel Medical School, Thomas Jefferson University, Philadelphia, PA 19107, USA"},{"name":"Department of Ophthalmology, Thomas Jefferson University, Philadelphia, PA 19107, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Zhao, X., Chen, J., Sun, H., Zhang, Y., and Zou, D.
