The study of MicroRNAs (miRNAs) will provide a new avenue for drug discovery for diseases such as Age-Related Macular Degeneration (AMD), and have applications for other retinal diseases such as diabetic retinopathy, retinitis pigmentosa, retinoblastoma and other neurodegenerative diseases such as Parkinson’s and Alzheimer’s. MiRNA are small non-coding RNA molecules that post transcriptionally regulate gene expression. While miRNAs were only identified in humans as recently a
