Summary
The endoplasmic reticulum (ER) is key to cell balance and the unfolded protein response, impacting cancer. Understanding ER stress in cancer may reveal new therapeutic targets.
Area of Science:
- Cellular Biology
- Oncology
- Molecular Biology
Background:
- The endoplasmic reticulum (ER) is crucial for maintaining cellular homeostasis.
- The unfolded protein response (UPR) pathway, initiated in the ER, is increasingly linked to cancer development and progression.
- Environmental challenges within the tumor microenvironment significantly impact ER function.
Purpose of the Study:
- To investigate ER-mediated signaling and regulatory mechanisms in the context of cancer.
- To explore the role of ER stress in cancer-related pathologies, including hypoxia, angiogenesis, and chemotherapeutic resistance.
- To understand how ER-resident molecular machines contribute to cancer pathobiology.
Main Methods:
- Review and synthesis of current literature on ER stress and cancer.
- Analysis of signaling pathways involved in ER homeostasis and UPR.
- Discussion of molecular mechanisms underlying ER deregulation in cancer.
Main Results:
- ER stress and UPR are implicated in tumor growth, metastasis, and resistance to therapy.
- Hypoxia, angiogenesis, and chemotherapeutic agents induce significant ER stress in cancer cells.
- Deregulated ER-resident molecular machines contribute to cancer pathology.
Conclusions:
- The ER plays a critical role in cancer pathobiology through its involvement in stress responses.
- Targeting ER-mediated signaling pathways offers potential therapeutic strategies for cancer treatment.
- Further research into ER stress sensing, signaling, and adaptation is essential for advancing cancer therapy.

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...

01:31Regulation 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...
03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

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...
