Endoplasmic reticulum (ER) dysfunction contributes to kidney diseases. Strategies to maintain ER homeostasis, like the unfolded protein response and autophagy, offer potential therapeutic avenues for kidney disorders.
Area of Science:
- Cell Biology
- Nephrology
- Molecular Mechanisms
Background:
- The endoplasmic reticulum (ER) is crucial for protein/lipid synthesis, calcium (Ca2+) regulation, and organelle communication.
- ER homeostasis disruption leads to cellular damage, implicated in kidney disease onset and progression.
Purpose of the Study:
- To review the molecular mechanisms linking ER dysfunction to kidney pathologies.
- To explore endogenous protective strategies for ER homeostasis in kidney disorders.
Main Methods:
- Literature review of recent research on ER homeostasis and kidney diseases.
- Analysis of molecular pathways including unfolded protein response, ER-associated protein degradation, and autophagy (ER-phagy).
Main Results:
- ER homeostasis dysregulation, including protein/lipid accumulation and Ca2+ imbalance, is a key factor in kidney pathologies.
- Cellular protective mechanisms like UPR, ERAD, and autophagy are vital for maintaining ER function.
Conclusions:
- Understanding ER dysfunction mechanisms is critical for developing novel therapeutic strategies for kidney diseases.
- Targeting endogenous ER protective pathways presents a promising approach for treating kidney disorders.

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...
