UPR, Unfolded Protein Response: Click to Expand ⟱
Source:
Type:
Cellular stress response related to the endoplasmic reticulum (ER) stress, which involves protein folding, quality control, and signaling pathways. The unfolded protein response (UPR) is the cells' way of maintaining the balance of protein folding in the endoplasmic reticulum. (UPR) is triggered by the presence of misfolded proteins in the endoplasmic reticulum.
The UPR is a cellular stress response activated by the accumulation of unfolded or misfolded proteins in the endoplasmic reticulum (ER).
- It is primarily mediated by three ER-resident sensors: IRE1α, PERK, and ATF6.

Cancer cells often experience high levels of protein synthesis, hypoxia, nutrient deprivation, and oxidative stress, all of which can activate the UPR.
– Numerous studies have reported that key UPR components (e.g., GRP78/BiP, IRE1α, PERK, CHOP) are overexpressed in various malignancies such as breast, pancreatic, lung, and prostate cancers.

Unfolded Protein Response is typically upregulated in cancers and is associated with poorer prognosis due to its role in promoting cell survival, adaptation to stress, and therapeutic resistance. Although the UPR harbors the potential for tumor-suppressive (apoptotic) effects under severe stress conditions, its predominant activation in tumors supports an adaptive, protumorigenic state that facilitates cancer progression. Targeting UPR components and modulating this balance remain promising therapeutic strategies.
