Insights

MicroRNAs (miRNAs) are key regulators of cellular stress responses, playing a significant role in disease development. Understanding miRNA functions offers new therapeutic opportunities for various pathologies.

Area of Science:

  • Molecular Biology
  • Cellular Biology
  • Genetics

Background:

  • Disease arises from inadequate responses to physiological and pathophysiological stress.
  • MicroRNAs (miRNAs) have emerged as critical regulators of cellular behavior during stress.
  • These small RNAs play a significant role in pathological conditions.

Purpose of the Study:

  • To review emerging principles of miRNA regulation in stress signaling pathways.
  • To apply these principles to understand the role of miRNAs in disease.
  • To highlight challenges and opportunities in miRNA-based therapeutics.

Main Methods:

  • Review of recent scientific literature (last 10 years) on miRNA regulation and disease.
  • Analysis of stress signaling pathways influenced by miRNAs.
  • Discussion of mechanistic dissection and therapeutic development strategies.

Main Results:

  • Identification of a recurring paradigm where miRNAs regulate cellular responses to stress.
  • Elucidation of specific miRNA roles in various disease contexts.
  • Highlighting the complexity of miRNA function and therapeutic targeting.

Conclusions:

  • MicroRNAs are integral to cellular stress responses and disease pathogenesis.
  • Further research into miRNA mechanisms is crucial for developing effective therapeutics.
  • Targeting miRNAs presents unique challenges and significant therapeutic potential.

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 ends...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
Role of ER in the Secretory Pathway01:17

Role of ER in the Secretory Pathway

Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...
NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.
