Summary
The unfolded protein response (UPR) is hijacked by cancer cells for survival and immune evasion. Understanding UPR
Area of Science:
- Cellular Biology
- Cancer Research
- Immunology
Background:
- The unfolded protein response (UPR) is a cellular process crucial for maintaining endoplasmic reticulum (ER) homeostasis.
- UPR plays non-canonical roles in lipid metabolism and immune system modulation within the tumor microenvironment.
- Cancer cells exploit UPR to enhance survival and evade immune surveillance, though mechanisms are not fully understood.
Purpose of the Study:
- To critically review canonical and non-canonical UPR mechanisms in cancer.
- To dissect UPR's crosstalk with cell fate pathways and lipid metabolism in cancer.
- To propose therapeutic strategies targeting UPR in cancer treatment.
Main Methods:
- Literature review and critical analysis of existing studies on UPR in cancer.
- Mechanistic dissection of UPR's role in tumor immune microenvironment and lipid metabolism.
- Exploration of potential therapeutic strategies and combination therapies.
Main Results:
- UPR is a key player in cancer cell survival and immune evasion.
- UPR crosstalks with lipid metabolism and other signaling pathways to influence cancer progression.
- Targeting UPR presents therapeutic opportunities but requires careful consideration.
Conclusions:
- A deeper mechanistic understanding of UPR in cancer is essential for therapeutic development.
- Patient stratification, biomarker development, and combination therapies are crucial for maximizing UPR-targeted treatment efficacy.
- Exploiting UPR offers a promising avenue for novel cancer therapeutics.

01:37The Unfolded Protein Response
6.2K
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...

01:31Regulation of the Unfolded Protein Response
2.9K
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...

02:04Protein-protein Interfaces
14.4K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

01:26Protein Modifications in the RER
6.8K
Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal...

01:19Interactions Between Signaling Pathways
7.2K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
