Insights

Androgens play a crucial role in cardiovascular repair and regeneration by stimulating new blood vessel growth (angiogenesis). This finding has implications for therapeutic angiogenesis and androgen replacement therapies in aging men.

Area of Science:

  • Cardiovascular Science
  • Endocrinology
  • Regenerative Medicine

Background:

  • Significant sex differences exist in cardiovascular disease incidence and outcomes.
  • While estrogen's role in angiogenesis is well-studied, androgen's role remains largely unexplored.
  • Cardiovascular adaptation and repair following ischemia/infarction may involve intrinsic sex differences.

Purpose of the Study:

  • To review the role of androgens in cardiovascular repair and regeneration.
  • To explore the mechanisms by which androgens influence angiogenesis.
  • To discuss the implications for therapeutic interventions.

Main Methods:

  • Review of existing scientific literature on androgens, angiogenesis, and cardiovascular repair.
  • Analysis of studies investigating androgen effects on vascular endothelial growth factor (VEGF) and erythropoietin.
  • Examination of research on endothelial progenitor cells and hormonal regulation.

Main Results:

  • Evidence suggests androgens are important for cardiovascular repair and regeneration.
  • Androgens stimulate angiogenesis through VEGF-related pathways and erythropoietin production.
  • Endothelial progenitor cells, key to angiogenesis, are targets of androgen action.

Conclusions:

  • Androgens significantly contribute to cardiovascular repair and regeneration.
  • Therapeutic angiogenesis and androgen replacement may benefit aging and hypogonadal men.
  • Further research into androgen-mediated cardiovascular effects is warranted.

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 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...
Overview of Regeneration and Repair01:19

Overview of Regeneration and Repair

Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Hormonal Regulation of Blood Pressure01:17

Hormonal Regulation of Blood Pressure

Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
