As proper blood supply to the retina is critical to maintain its high metabolic demand, any impediment to blood flow can lead to a decrease in oxygen supply, resulting in retinal ischemia. In the pathogenesis of DR, including diabetic macular edema (DME), elevated blood glucose leads to blood-retina barrier (BRB) disruptions, vascular leakage, and capillary occlusion and dropouts, causing insufficient delivery of oxygen to the retina, and ultimately resulting in visual impairment. Other potential causes of DR include neuronal dysfunction in the absence of vascular defect, genetic, and environmental factors. The exact disease progression remains unclear and varies from patient to patient. Vascular leakage leading to edema clearly links to visual impairment and remains an important target for therapy. Despite recent advances in the treatment of DME and DR with anti-VEGFs, effective therapies with new mechanisms of action to address current treatment limitations regarding vessel regeneration and reperfusion of ischemic retinal areas are still needed. The Wnt signaling pathway plays a critical role in proper vascular development and maintenance in the retina, and thus provides a novel therapeutic approach for the treatment of diabetic and other retinopathies. In this review, we summarize the potential of this pathway to address treatment gaps with current therapies, its promise as a novel and potentially disease modifying therapy for patients with DR and opportunities in other retinal vascular diseases.<\/jats:p>","DOI":"10.3390\/pharmaceutics14112476","type":"journal-article","created":{"date-parts":[[2022,11,17]],"date-time":"2022-11-17T03:26:04Z","timestamp":1668655564000},"page":"2476","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":39,"title":["Selective Activation of the Wnt-Signaling Pathway as a Novel Therapy for the Treatment of Diabetic Retinopathy and Other Retinal Vascular Diseases"],"prefix":"10.3390","volume":"14","author":[{"given":"Huy","family":"Nguyen","sequence":"first","affiliation":[{"name":"Surrozen Operating, Inc., 171 Oyster Point Blvd, Suite 400, South San Francisco, CA 94080, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sung-Jin","family":"Lee","sequence":"additional","affiliation":[{"name":"Surrozen Operating, Inc., 171 Oyster Point Blvd, Suite 400, South San Francisco, CA 94080, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7134-5685","authenticated-orcid":false,"given":"Yang","family":"Li","sequence":"additional","affiliation":[{"name":"Surrozen Operating, Inc., 171 Oyster Point Blvd, Suite 400, South San Francisco, CA 94080, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1580","DOI":"10.1016\/j.ophtha.2021.04.027","article-title":"Global Prevalence of Diabetic Retinopathy and Projection of Burden through 2045: Systematic Review and Meta-analysis","volume":"128","author":"Teo","year":"2021","journal-title":"Ophthalmology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1574","DOI":"10.1016\/j.survophthal.2022.06.004","article-title":"Unconventional avenues to decelerated diabetic retinopathy","volume":"67","author":"Takkar","year":"2022","journal-title":"Surv.
