Summary
This study reveals long non-coding RNAs (lncRNAs) play a key role in ocular neovascularization, a major cause of vision loss. Targeting these dysregulated lncRNAs may offer new treatments for eye vascular diseases.
Area of Science:
- Ophthalmology
- Molecular Biology
- Genetics
Background:
- Pathological neovascularization causes significant vision loss.
- Long non-coding RNAs (lncRNAs) are regulatory molecules implicated in various diseases.
- The role of lncRNAs in ocular neovascularization remains largely unknown.
Purpose of the Study:
- To investigate the role of lncRNAs in ocular neovascularization.
- To identify differentially expressed lncRNAs during ocular neovascularization phases.
- To explore potential therapeutic targets for neovascular eye diseases.
Main Methods:
- Construction of a murine model for ocular neovascularization.
- Microarray analysis to determine lncRNA expression profiles.
- Pearson correlation analysis and co-expression network construction.
- Gene Ontology (GO) and KEGG pathway analyses.
Main Results:
- Identified 326 up-regulated and 51 down-regulated lncRNAs during disease phases.
- lncRNA-mRNA co-expression networks revealed significant biological modules and pathways (e.g., MAPK signaling).
- Vax2os1 and Vax2os2 were dynamically expressed and altered in neovascular age-related macular degeneration (AMD) patients' aqueous humor.
Conclusions:
- lncRNAs are dynamically regulated during ocular neovascularization.
- Specific lncRNAs, like Vax2os1 and Vax2os2, show potential as biomarkers and therapeutic targets for neovascular eye diseases.
- This study provides novel insights into the molecular pathogenesis of ocular neovascularization.

7.5K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

01:10Mechanism of Angiogenesis
6.4K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

01:24Regulation of Angiogenesis and Blood Supply
2.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

1.7K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
