Insights

MicroRNAs (miRNAs) regulate gene expression in the retina. Recent advances highlight their functional roles in retinal development, function, and disease, with new technologies aiding deeper understanding.

Area of Science:

  • Molecular Biology
  • Genetics
  • Ophthalmology

Background:

  • MicroRNAs (miRNAs) are small RNA molecules regulating gene expression post-transcriptionally.
  • Over 250 miRNAs are expressed in the vertebrate retina.
  • miRNA gene regulation impacts retinal development, function, and disease.

Purpose of the Study:

  • To review recent advances in understanding the functional roles of vertebrate retinal miRNAs.
  • To discuss the physiological impact of specific miRNAs in retinal development and mature retinas.
  • To highlight emerging technologies for studying retinal miRNA gene regulation.

Main Methods:

MicroRNAs

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 the pre-miRNA...
