Summary
This network pharmacology study demonstrates that berberine treatment can protect against diabetic retinal injury by modulating key gene expression, including downregulation of Atp7a, Ppl, Ogn, and other upregulated diabetic genes. While the findings suggest potential therapeutic relevance, the research is primarily preclinical (rat model) and does not directly inform lighting design or circadian-based interventions.
Key Findings
- OCT results showed thickening of the outer nucleus, inner layer, and outer accessory RPE layer following berberine treatment, indicating structural retinal protection.
- Berberine-treated rats showed significantly higher learning and cognitive function compared to diabetic controls by day 5 of water maze testing.
- 10 key proteins were identified via 4D-DIA quantitative proteomic analysis; berberine treatment reversed expression patterns of 7 upregulated genes (Atp7a, Ppl, Ogn, Nsmcel, Mme, Lmo4, Ca1, Fn1) and 2 downregulated genes (Dennd1a, Utp6) seen in the diabetic group.
- Molecular docking confirmed stable binding between berberine and 7 of the 10 target proteins (excluding Fn1, Ogn, and Utp6).
- PPI analysis of 353 combined genes yielded 331 interacting genes for GO and KEGG pathway analysis, supporting a multi-target mechanism of action.
