Summary
Pulmonary arterial hypertension (PAH) involves lung artery cell growth. Researchers found the protein Nogo-B contributes to PAH development under stress, suggesting it as a potential therapeutic target.
Area of Science:
- Cardiovascular Research
- Cell Biology
- Pulmonary Medicine
Background:
- Pulmonary arterial hypertension (PAH) is a severe condition marked by high blood pressure in lung arteries.
- Vascular remodeling, driven by cell proliferation, is a key feature of PAH.
- Endoplasmic reticulum stress and mitochondrial dysfunction in smooth muscle cells are implicated in PAH pathogenesis.
Purpose of the Study:
- To investigate the role of the vascular remodeling protein Nogo-B in the development of pulmonary arterial hypertension (PAH).
- To explore the potential of Nogo-B as a therapeutic target for PAH.
Main Methods:
- The study by Sutendra et al. examined the function of Nogo-B in the context of hypoxia-induced stress.
- Investigated the impact of Nogo-B on vascular cell proliferation and remodeling in pulmonary arteries.
Main Results:
- Nogo-B was identified as a protein involved in the vascular remodeling process characteristic of PAH.
- The study demonstrated that Nogo-B plays a role in the development of PAH, particularly under hypoxia-induced stress.
Conclusions:
- Nogo-B is implicated in the pathogenesis of pulmonary arterial hypertension.
- Targeting Nogo-B presents a potential therapeutic strategy for treating PAH.

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...
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...
01:34Directing Proteins to the Rough Endoplasmic Reticulum
The organelle-specific signaling sequences direct proteins synthesized in the cytosol to their final destination like ER, mitochondria, peroxisomes, etc. Some of the proteins directed to ER are then trafficked via vesicles to other organelles within the cell or the extracellular environment through the Golgi complex. For example, the rough ER synthesizes soluble proteins for transportation to the lysosomes or secretion out of the cell. It can also synthesize transmembrane proteins that can...
01:27Post-translational Translocation of Proteins to the RER
A sizable fraction of proteins destined for ER are first synthesized in the cell cytosol and then transported across the ER membrane–a process called post-translational translocation. Similar to cotranslationally translocated proteins, these proteins also use the Sec translocon complex to enter the ER lumen.

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...
01:20Cotranslational Protein Translocation
Translocation of proteins across membranes is an ancient process that occurs even in bacteria and archaebacteria. In fact, the components of the translocation machinery are still conserved between prokaryotes and eukaryotes.
