Summary
Cellular disturbances trigger endoplasmic reticulum (ER) stress and the unfolded protein response (UPR). MicroRNAs (miRNAs) are key regulators of the UPR, influencing cell fate decisions during ER stress.
Area of Science:
- Molecular biology
- Cellular biology
- Genetics
Background:
- Endoplasmic reticulum (ER) stress occurs due to misfolded protein accumulation.
- The unfolded protein response (UPR) is a cellular signaling pathway activated by ER stress to restore homeostasis.
- UPR signaling complexity can lead to adaptive or apoptotic outcomes.
Purpose of the Study:
- To investigate the role of microRNAs (miRNAs) in regulating the UPR.
- To understand how miRNAs influence the adaptive/apoptotic switch in response to ER stress.
- To identify specific miRNAs that target key UPR components.
Main Methods:
- Analysis of miRNA regulation in cellular models of ER stress.
- Investigating the impact of specific miRNAs on UPR signaling pathways.
- Gene expression analysis to identify miRNA targets within the UPR.
Main Results:
- MicroRNAs (miRNAs) act as critical regulators of the UPR.
- Specific miRNAs have been identified that directly target and modulate key UPR signaling components.
- miRNA activity influences the balance between adaptive and apoptotic cellular responses to ER stress.
Conclusions:
- MicroRNAs are pivotal in controlling the cellular fate during ER stress.
- Targeting specific miRNAs could offer therapeutic strategies for diseases associated with ER stress.
- Further research into miRNA-UPR interactions is crucial for understanding cellular stress responses.

01:31Regulation 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...
01:37The Unfolded Protein Response
The ER is the hub of protein synthesis in a cell. It has robust systems to quality control protein folding and also for degradation of terminally misfolded proteins. Under normal conditions, a small proportion of misfolded proteins that cannot be salvaged need to be transported to the cytoplasm by the ER-associated degradation or ERAD pathways. However, if the ERAD cannot handle the misfolded proteins, the cell activates the unfolded protein response or UPR to adjust the protein folding...
01:17Role 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...

01:32Export of Misfolded Proteins out of the ER
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...
02:51mRNA Stability and Gene Expression
The structure and stability of mRNA molecules regulates gene expression, as mRNAs are a key step in the pathway from gene to protein. In eukaryotes, the half-life of mRNA varies from a few minutes up to several days. mRNA stability is essential in growth and development. The absence of the proteins regulating its stability, such as tristetraprolin in mice, can cause systemic issues, including bone marrow overgrowth, inflammation, and autoimmunity.
