Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

4.0K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Role of ER in the Secretory Pathway01:17

Role of ER in the Secretory Pathway

7.8K
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...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

3.2K
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...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

7.7K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

The Unfolded Protein Response01:37

The Unfolded Protein Response

7.0K
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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

5.1K
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.
The mTOR pathway or the...

  • Physiology
  • Molecular Biology
  • Pathology

Background:

  • Tissue vascularization is essential for delivering oxygen, nutrients, and immune cells, and removing waste.
  • Angiogenesis, or new blood vessel formation, is regulated by cellular energy status and metabolic imbalance.
  • Endoplasmic reticulum (ER) stress pathways can generate signals that modulate blood vessel growth.

Purpose of the Study:

  • To review the link between ER stress and angiogenesis.
  • To discuss the role of ER stress in diseases with altered vascular homeostasis.

Main Methods:

  • Literature review of studies on ER stress and angiogenesis.
  • Analysis of signaling pathways connecting ER stress to vascular regulation.

Main Results:

  • ER stress can induce both pro-angiogenic and anti-angiogenic signals.
  • These signals influence vascular homeostasis.

Conclusions:

  • ER stress is a significant factor in regulating angiogenesis.
  • Understanding this link has implications for treating vascular-related diseases like cancer, retinopathies, and atherosclerosis.
