Insights

This review explores angiogenesis, the formation of new blood vessels, focusing on its therapeutic potential in heart disease and its role in arterial diseases like atherosclerosis. It details molecular mechanisms and regulators.

Area of Science:

  • Cardiovascular Biology
  • Molecular Medicine
  • Vascular Biology

Background:

  • New blood vessel formation (angiogenesis) is crucial in cancer but less studied therapeutically for ischemic heart conditions.
  • Understanding angiogenesis in coronary heart disease reveals compensatory healing in myocardial ischemia and infarction.
  • Angiogenesis can influence arterial diseases, including atherosclerotic plaque development and instability.

Purpose of the Study:

  • To review the molecular mechanisms of angiogenesis.
  • To analyze angiogenesis during development, adult new vessel formation (neoangiogenesis), and arteriogenesis.
  • To discuss the role of neoangiogenesis in atherosclerotic plaque progression.

Main Methods:

  • Literature review of molecular mechanisms regulating angiogenesis.
  • Analysis of angiogenesis in different physiological and pathological contexts.
  • Discussion of regulatory factors involved in neovascularization.

Main Results:

  • Detailed overview of molecular pathways governing angiogenesis.
  • Exploration of angiogenesis across developmental stages and in adults.
  • Examination of the dual role of angiogenesis in healing and disease progression.

Conclusions:

  • Angiogenesis is a complex process with therapeutic implications for ischemic heart disease.
  • Neoangiogenesis plays a significant role in the development and instability of atherosclerotic plaques.
  • Further research into angiogenesis regulators is vital for understanding and treating cardiovascular and arterial diseases.

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...
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...
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...
Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
Overview of the Vascular System01:20

Overview of the Vascular System

The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...
Overview of Cell-Matrix Interactions01:24

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...
