However, the interobserver variability among pathologists in reading WSIs is inevitable. Thus, artificial intelligence (AI) technology is crucial.

To understand the mechanisms underlying retinal neovascularization, using the oxygen-induced retinopathy (OIR) model, we performed two-dimensional gel matrix-assisted laser desorption/ionization time-of-flight/time-of-flight analysis of normoxic and 24-hour post-OIR mice pups' retinas. Two-dimensional gel analysis revealed that glucose-regulated protein 78 (GRP78) is one of the several molecules induced by OIR in the retinal endothelial cells (ECs). Vascular endothelial growth factor A (VEGFA) also induced GRP78 expression independent of endoplasmic reticulum stress response in human retinal microvascular endothelial cells, and depletion of its levels reduced VEGFA-induced EC angiogenic responses. Consistent with these observations, EC-specific deletion of GRP78 inhibited OIR-induced retinal neovascularization. In exploring the mechanisms, we found that GRP78 binds with vascular endothelial-cadherin and releases adherens junction- but not Wnt-mediated β-catenin and that β-catenin, in turn, via interacting with STAT3, triggers cyclin D1 expression. Furthermore, depletion of β-catenin or cyclin D1 levels negated VEGFA-induced EC angiogenic responses and OIR-induced retinal neovascularization. EC-specific deletion of GRP78 also suppressed OIR-induced vascular leakage. In elucidating the upstream signaling, we found that activating transcription factor 6 mediates GRP78 induction in the modulation of VEGFA-induced EC angiogenic responses and OIR-induced retinal neovascularization. Together, these observations reveal that GRP78, independent of its response to endoplasmic reticulum stress, is involved in mediating EC angiogenic responses by VEGFA and retinal neovascularization by OIR.

CK1ε<sup>ΔHEP</sup> WD-fed mice showed significantly down-regulated TNF receptor–associated factor (TRAF) 3, phosphorylated (p) transforming growth factor-β–activated kinase 1, p–TRAF-associated NF-κB activator (TANK)-binding kinase 1 (TBK1), and p-AKT levels, thereby affecting downstream mitogen-activated protein kinase signaling, indicating a potential mechanism for the observed rescue. Finally, pharmacologic inhibition of CK1ε with PF670462 improved palmitic acid–induced steatohepatitis <em>in vitro</em> and attenuated WD-induced metabolic profile <em>in vivo</em>. In conclusion, CK1ε up-regulates TNF receptor–associated factor 3, which, in turn, causes transforming growth factor-β–activated kinase 1–dependent signaling, amplifies downstream mitogen-activated protein kinase signaling, modifies p-c-Jun levels, and exacerbates inflammation, all of which are factors in WD-induced metabolic dysfunction–associated steatotic liver disease.</div></div>","PeriodicalId":7623,"journal":{"name":"American Journal of Pathology","volume":"194 11","pages":"Pages 2106-2127"},"PeriodicalIF":4.7,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142046120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
