Summary
MicroRNA-328 (miR-328) is implicated in dry eye disease (DED). Topical anti-miR-328 eye drops effectively reduced DED signs and promoted corneal healing in animal models, suggesting a novel therapeutic approach.
Area of Science:
- Ophthalmology
- Molecular Biology
- Genetics
Background:
- Dry eye disease (DED) is a prevalent ocular surface condition.
- Benzalkonium chloride (BAC) and hyperosmotic stress are common inducers of DED in experimental models.
- MicroRNA-328 (miR-328) has been identified as potentially involved in DED pathogenesis.
Purpose of the Study:
- To investigate the role of miR-328 in DED.
- To evaluate the therapeutic potential of anti-miR-328 eye drops for DED treatment.
Main Methods:
- DED was induced in rabbits and mice using BAC.
- Animals received topical anti-miR-328 or saline eye drops.
- DED severity was assessed using corneal fluorescein staining, histological examination, apoptosis assays, and inflammatory cytokine analysis.
Main Results:
- Anti-miR-328 treatment significantly reduced corneal staining scores in both rabbits and mice compared to saline.
- Rabbit corneas treated with anti-miR-328 showed improved epithelial thickness and reduced apoptosis in epithelial and stromal cells.
- Anti-miR-328 demonstrated a trend towards reducing Meibomian gland orifice blockage.
Conclusions:
- Overexpression of miR-328 contributes to the development of DED.
- Anti-miR-328 eye drops offer a promising therapeutic strategy for DED by protecting corneal cells and enhancing re-epithelialization.

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

01:27Open Angle Glaucoma: Treatment
744
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
