Background:

  • Extracellular microRNAs (miRNAs) are found in biological fluids and are stable.
  • They are transported via vesicles, lipoproteins, and ribonucleoprotein complexes.
  • Altered miRNA signatures are observed in pathophysiologies like cardiovascular disease.

Purpose of the Study:

  • To review current knowledge on extracellular miRNA intercellular communication.
  • To highlight outstanding questions in the field.
  • To discuss the applicability of miRNA research to cardiovascular disease.

Main Methods:

  • Literature review of studies on extracellular miRNAs.
  • Analysis of miRNA transport mechanisms and cellular uptake.
  • Examination of miRNA's role in cell-to-cell communication.

Main Results:

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...

Regulated mRNA Transport02:22

Regulated mRNA Transport

In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing specific...

Transcellular Transport of Solutes

Transcellular transport of solutes is the movement of substances like monosaccharides and amino acids through polarized cells. This transport mechanism is primarily seen in epithelial and endothelial cells aided by membrane transport proteins such as channels and transporters. The tight junctions between these cells confine the membrane proteins to the two sides of the cell. The epithelial cells have distinct apical and basolateral domains. In contrast, the endothelial cells show the luminal...
