Within this investigation, DR was induced in rats with diabetes mellitus (DM) by subjecting them to a regimen involving a high-fat and high-sugar diet, coupled with intraperitoneal administration of streptozotocin (STZ) at a dosage of 45 mg/kg. Retinal damage in DR rats was assessed by means of hematoxylin and eosin (HE) staining. The serum levels of inflammatory and angiogenic factors were also measured. Additionally, the levels of tight junction proteins, angiogenic proteins, and inflammatory proteins in the retinas of DR model rats were assessed using Western blot (WB),immunohistochemistry(IHC) and immunofluorescence(IF). Moreover, bioinformatics and network pharmacology methodologies were utilized to pinpoint intersecting genes linked to DR and to elucidate the mechanism of action of Phl. This involved screening with Venny, conducting Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG)analyses, constructing a Protein-Protein Interaction (PPI) network, and performing molecular docking analysis. The results of this study demonstrated that Phl significantly normalized fasting glucose levels and reduced body weight, thereby alleviating obesity in DR rats after 12 weeks. Furthermore, the serum levels of inflammatory and angiogenic factors were considerably reduced in the drug-treated rats. WB, IHC and IF revealed increased expression of the tight junction proteins zonula occludens-1(ZO-1) and occludin in the retinas of drug-treated DR rats, validating the observed findings. Molecular biology validation experiments based on the predictions by network pharmacology indicated a substantial decrease in the expression levels of vascular endothelial growth factor (VEGF), notch homolog 1 (Notch1), and hypoxia inducible factor-1 (HIF-1α) in the retina upon treatment with Phl. This reduction resulted in the inhibition of neovascularization. Furthermore, Phl exhibited inhibitory effects on inflammatory pathways, leading to a decrease in cytokine release. The overexpression of VEGF was identified as a factor diminishing brain-derived neurotrophic factor(BDNF) expression while increasing the expression levels of inflammatory proteins. Therefore, the results of this research demonstrate that Phl has the potential to protect the retina of DR rats by inhibiting VEGF expression. This protective effect may be associated with the modulation of the VEGF/BDNF/NF-κB signaling pathway.</div></div>","PeriodicalId":12177,"journal":{"name":"Experimental eye research","volume":"254 ","pages":"Article 110329"},"PeriodicalIF":3.0,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143585112","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}

Here, we observed a decline in SIRT3 expression in human corneal epithelial cells (HCE-Ts) and the corneal conjunctiva of mice as the disease advanced. Overexpression of SIRT3 in HCE-Ts reduced the accumulation of reactive oxygen species (ROS), inflammatory cytokines, and the rate of apoptosis, while its inhibition had the opposite effect. Importantly, the function of SIRT3 was exerted through the enhancement of autophagic flux. Further studies have shown that chloroquine-induced inhibition of autophagy neutralized the beneficial effects of SIRT3. In our in vivo experiments, the application of eye drops containing a SIRT3 agonist ameliorated the symptoms of DED and increased corneal autophagy in mice. Mechanistically, our study identified that the deacetylation and nuclear translocation of FOXO1 (Forkhead box O1) are pivotal for the SIRT3-mediated enhancement of autophagic flux.

Regeneration of RGCs and reconstruction of the neural connections between the retina and the brain is considered an effective strategy to promote visual restoration in patients with glaucoma. However, there are currently no effective methods for regenerating RGCs to restore vision in clinical practice. Microglia are a type of glial cells that regulate the immune response in the retina and central nervous system (CNS), whether they have pluripotency and be reversed into RGCs remains unclear and challenging. This study revealed that the ectopic expression of multiple genes (<em>Brn3b</em>, <em>Sox2</em>, <em>Cbln1</em>, and <em>NP1</em>, referred to as <em>BSCN</em>) in microglia can promote their conversion into RGC-like cells by microglia fate lineage tracing <em>in vivo</em>. The regenerated RGC-like cells project axons to the distant brain and reconstruct the visual neural circuit, restoring the impaired vision in adult mice with acute glaucoma induced by retinal ischemia–reperfusion (I/R) injury. Furthermore, the regenerated RGC-like cells could survive stably for up to one year, and the same regeneration strategy was performed in older mice with acute glaucoma, which confirmed the effectiveness of the <em>BSCN</em> reprogramming to regenerate RGC-like cells. In summary, we have identified the microglia as a new type of reprogramming seed cells, and four key genes were found to be involved in regenerating RGC-like cells to restore vision.

The predominance of clinical evidence supports the classical “epithelium-off” RIB-UV-CXL method being more effective in halting ectasia progression than various “epithelium-on” methods, where the corneal epithelium is maintained intact. Corneal transparency results from the precise organization of collagen fibrils and extracellular matrix, along with transparent keratocytes. The mild and transient stromal opacity seen after standard RIB-UV-CXL is linked to changes in hydration, cellularity, and matrix composition. As hydration normalizes, opacity arises from the development of corneal fibroblasts and their secretion of disordered extracellular matrix materials including collagens. Over months, as the epithelial basement membrane regenerates, transitioning stromal cells either undergo apoptosis or revert to keratocan-positive keratocytes, restoring stromal transparency. In normal healing after standard RIB-UV-CXL, the stroma is eventually repopulated predominantly by keratocytes without significant persisting fibroblasts, immune cells, or myofibroblasts.
