Regulation of Angiogenesis and Blood Supply01:24

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...
Oogenesis02:07

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...
Targeted Cancer Therapies02:57

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...
Mechanism of Angiogenesis01:10

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...

Area of Science:

  • Reproductive biology and angiogenesis research.

Background:

  • The ovary is crucial for studying physiological neovascularization.
  • Key regulators of ovarian angiogenesis include vascular endothelial growth factor (VEGF), delta-like ligand 4 (DLL4), thrombospondin-1, prokineticin-1, and prostaglandin E2.

Purpose of the Study:

  • To explore the therapeutic potential of targeting molecular pathways regulating ovarian angiogenesis.
  • To review the role of angiogenesis manipulation in managing pathological ovarian conditions.

Main Methods:

  • Literature review on ovarian angiogenesis and its molecular regulators.
  • Analysis of preclinical and clinical studies involving targeted angiogenesis therapies.

Main Results:

  • Targeting angiogenic pathways can promote ovarian angiogenesis, enhancing tissue and follicle survival.
  • Angiogenesis modulation is beneficial in ovarian hyperstimulation syndrome, polycystic ovary syndrome, and ovarian cancer.

Conclusions:

  • Manipulation of angiogenic pathways holds significant therapeutic promise for diverse ovarian pathologies.
  • Targeted angiogenesis therapies are increasingly relevant in both preclinical and clinical ovarian disease management.
