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...

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...

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Oogenesis

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Overview of Cell-Matrix Interactions

Overview of Cell-Matrix Interactions

The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...

Area of Science:

Gynecology
Pathophysiology
Molecular Biology

Background:

Endometriosis is a prevalent gynecological condition with substantial morbidity and socioeconomic impact.
The underlying pathophysiology of endometriosis remains poorly understood, contributing to inadequate treatments and high recurrence rates.
Existing theories fail to fully explain all disease manifestations and the establishment of endometriotic implants.

Purpose of the Study:

To review the basic mechanisms of angiogenesis and vasculogenesis in the human eutopic endometrium.
To explore the application of this knowledge to endometriotic implants.
To discuss molecular mechanisms of angiogenesis and vasculogenesis for potential therapeutic strategies in endometriosis treatment.

Main Methods:

Literature review focusing on angiogenesis and vasculogenesis.
Analysis of molecular mechanisms involved in new vessel formation.
Application of endometrial vascularization data to endometriotic implants.

Main Results:

New vessel formation (angiogenesis and vasculogenesis) is a recognized feature of endometriosis, crucial for lesion establishment and growth.
Understanding these vascularization mechanisms in the eutopic endometrium provides insights into endometriotic implant development.
Molecular pathways governing angiogenesis and vasculogenesis are key targets for therapeutic intervention.

Conclusions:

Targeting angiogenesis and vasculogenesis offers a promising therapeutic avenue for endometriosis.
Further research into the molecular mechanisms can lead to more effective treatments.
A deeper understanding of endometriosis pathophysiology is essential for improving patient outcomes.
