Hypothesis
How does high glucose affect gene expression in human trabecular meshwork cells?
Conclusion
High glucose conditions lead to significant changes in gene expression that may contribute to trabecular meshwork dysfunction and increased glaucoma risk in diabetic patients.
Supporting Evidence
- High glucose conditions resulted in 25 significantly differentially expressed genes.
- TXNIP was significantly upregulated, indicating increased oxidative stress and apoptosis.
- Downregulation of autophagy-related genes suggests compromised protein quality control.
- Immune response genes were upregulated, indicating an inflammatory response.
- Increased expression of fibrosis-related genes supports ECM accumulation in diabetic conditions.
Takeaway
When there's too much sugar in the blood, it can hurt the cells in our eyes, making it harder for them to work properly and increasing the chance of getting glaucoma.
Methodology
Primary human trabecular meshwork cells were cultured under normal and high glucose conditions, followed by mRNA sequencing and confirmatory quantitative PCR.
