Using a mouse model of ROP and samples from DR patients, we found that the highly homologous and homeostatic erythroblast transformation-specific (ETS) family transcription factors ETS-related gene (ERG) and Friend leukemia integration 1 (FLI1) are downregulated in endothelial cells (ECs) of retinal capillaries prior to their regression in early stages of these diseases. We developed a mouse model of inducible EC-specific overexpression of\n                    <jats:italic toggle=\"yes\">Erg<\/jats:italic>\n                    and found it mitigates capillary regression, retinal neuron death, neovascularization, and visual defects in the ROP model.\n                    <jats:italic toggle=\"yes\">Erg<\/jats:italic>\n                    overexpression also reduces capillary regression in early stages of a murine DR model.

Altogether, our data demonstrate that deletion of homeostatic endothelial ETS factors promotes capillary regression, while maintenance of even one of these factors prevents regression. These findings offer insights into approaches for preventing and treating retinopathies at different stages of these diseases.\n                  <\/jats:p>","DOI":"10.1073\/pnas.2507194122","type":"journal-article","created":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T15:49:17Z","timestamp":1758642557000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":4,"title":["Targeting endothelial ERG to mitigate vascular regression in retinopathies"],"prefix":"10.1073","volume":"122","author":[{"given":"Eric","family":"Ma","sequence":"first","affiliation":[{"name":"Cardiovascular Biology Research Program, Oklahoma Medical Research Foundation","place":["Oklahoma City"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5859-7714","authenticated-orcid":false,"given":"Christopher M.","family":"Schafer","sequence":"additional","affiliation":[{"name":"Cardiovascular Biology Research Program, Oklahoma Medical Research Foundation","place":["Oklahoma City"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Xie","sequence":"additional","affiliation":[{"name":"Cardiovascular Biology Research Program, Oklahoma Medical Research Foundation","place":["Oklahoma City"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-0464-0139","authenticated-orcid":false,"given":"Yelyzaveta","family":"Rudenko","sequence":"additional","affiliation":[{"name":"Cardiovascular Biology Research Program, Oklahoma Medical Research Foundation","place":["Oklahoma City"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-6755-9498","authenticated-orcid":false,"given":"John T.
