Summary
Tumor cells release extracellular vesicles that promote blood vessel growth (angiogenesis) essential for cancer spread. These vesicles contain molecules that signal endothelial cells to support tumor development.
Area of Science:
- Oncology
- Cell Biology
- Molecular Biology
Background:
- Angiogenesis is vital for tumor growth and metastasis.
- Tumor cells release extracellular vesicles (EVs) that interact with endothelial cells.
- These EVs play a significant role in promoting angiogenesis.
Purpose of the Study:
- To review the role of tumor-derived EVs in promoting angiogenesis.
- To summarize the molecular mechanisms by which EVs activate pro-angiogenic signaling.
Main Methods:
- Literature review of recent studies on tumor-derived EVs and angiogenesis.
- Analysis of molecular cargo within EVs, including microRNAs, long non-coding RNAs, and proteins.
- Examination of signaling pathways activated in endothelial cells upon EV uptake.
Main Results:
- Tumor-derived EVs contain various bioactive molecules (miRNAs, lncRNAs, proteins).
- These molecules activate pro-angiogenic signaling pathways within endothelial cells.
- EVs facilitate the formation of new blood vessels, supporting tumor progression.
Conclusions:
- Tumor-derived extracellular vesicles are key mediators of tumor-induced angiogenesis.
- Understanding these molecular mechanisms offers potential therapeutic targets for cancer treatment.

01:10Mechanism of Angiogenesis
6.9K
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...

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

3.5K
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...

7.0K
Insulin secretory vesicles release insulin to stimulate blood glucose uptake and regulate carbohydrate metabolism. When the blood glucose levels increase, glucose enters the pancreatic β-islet cells through glucose transporters. Once inside, glucose is metabolized through glycolysis, the citric acid cycle, and the electron transport chain, producing ATP. This increase in ATP concentration closes ATP-sensitive potassium channels, leading to depolarization of the membrane and the opening of...

9.6K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...
