Abstract:
Increased endoplasmic reticulum (ER) stress and the activated unfolded protein response (UPR) signaling associated with it play key roles in physiological processes as well as under pathological conditions. The UPR normally protects cells and re-establishes cellular homeostasis, but prolonged UPR activation can lead to the development of various pathologies. These features make the UPR signaling pathway an attractive target for the treatment of diseases whose pathogenesis is characterized by chronic activation of this pathway. Here, we focus on the molecular signaling pathways of the UPR and suggest possible ways to target this response for therapeutic purposes.
Insights
The unfolded protein response (UPR) helps cells maintain balance, but chronic UPR activation causes disease. Targeting UPR signaling offers potential therapeutic strategies for various pathologies.
Area of Science:
- Molecular Biology
- Cellular Biology
- Pathophysiology
Background:
- Endoplasmic reticulum (ER) stress is a cellular state that triggers the unfolded protein response (UPR).
- The UPR is a protective mechanism crucial for maintaining cellular homeostasis under stress.
- Dysregulation and prolonged activation of the UPR are implicated in the development of numerous diseases.
Purpose of the Study:
- To elucidate the molecular signaling pathways of the UPR.
