Mechanism of Angiogenesis

Mechanism of Angiogenesis

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...

Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

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 hydroxylase and factor...

Drugs that Stabilize Microtubules

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Background:

Microparticles, previously considered 'cell dust,' are now understood as crucial biological information vectors.
Their composition varies by origin, influencing the biological messages (proteins, mRNA, miRNA) they carry.
Microparticles are implicated in pathological processes within blood vessels, such as in hypertension and metabolic syndrome.

Purpose of the Study:

To explore the multifaceted roles of microparticles in biological systems.
To investigate the therapeutic potential of microparticles in angiogenesis.
To understand the mechanisms by which microparticles influence endothelial cells and vessel formation.

Main Methods:

Analysis of microparticle composition based on cellular origin.
Investigating direct and indirect mechanisms of microparticle action on angiogenesis.
Assessing the impact of microparticles on endothelial cell behavior in vitro and in vivo.

Main Results:

Microparticles act as carriers of both deleterious and therapeutic biological information.
They directly and indirectly modulate angiogenesis through various cellular interactions and signaling pathways.
Evidence shows microparticles promote the formation of new blood vessels, even under ischemic conditions.

Conclusions:

Microparticles possess significant therapeutic potential for conditions involving altered angiogenesis.
Their ability to influence endothelial cell function supports their use as novel therapeutic tools.
Further research into microparticle-based therapies is warranted for vascular pathologies.
