Gene network analyses unveil possible molecular basis underlying drug-induced glaucoma

Area of Science:

• Ophthalmology
• Pharmacogenomics
• Molecular Biology

Background:

• Drug-induced glaucoma (DIG) is a severe adverse drug reaction leading to irreversible blindness.
• The precise molecular mechanisms underlying glaucoma onset remain largely unknown.
• Understanding DIG is crucial for preventing vision loss and improving patient outcomes.

Purpose of the Study:

• To identify drugs associated with glaucoma development.
• To elucidate the molecular mechanisms and gene networks involved in DIG.
• To discover potential biomarkers for early detection and prognosis of DIG.

Main Methods:

• Data mining of adverse drug event databases and genome-wide gene expression data.
• Weighted Gene Co-expression Network Analysis (WGCNA) to identify gene interaction networks.
• Pathogenic risk assessment to pinpoint potential DIG biomarker genes.

Main Results:

• Identified 13 drugs strongly associated with glaucoma.
• Constructed a glaucoma-related gene network comprising 55 susceptible genes.
• Discovered that OTOF gene and eight others may serve as biomarkers for early-onset DIG prognosis.

Conclusions:

• This research systematically elucidates the molecular basis of DIG for the first time.
• Findings provide crucial insights into early-onset glaucoma prognosis.
• The study aids in developing improved therapeutic strategies for DIG.
