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...
Autoregulation of Blood Flow01:17

Autoregulation of Blood Flow

Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation.
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:

  • Vascular biology
  • Molecular genetics
  • Cardiovascular research

Background:

  • Hemodynamic forces, like shear stress, shape blood vessel development and function.
  • MicroRNAs (miRs) regulate gene expression, influencing vascular physiology.
  • Altered miR expression is linked to cardiovascular disease pathogenesis.

Purpose of the Study:

  • To investigate how hemodynamic forces, specifically shear stress, affect microRNA expression in endothelial cells.
  • To understand the role of specific microRNAs in vascular health and disease.
  • To explore the potential of microRNAs as diagnostic and therapeutic targets for cardiovascular diseases.

Main Methods:

  • Analysis of microRNA expression profiles in endothelial cells under varying shear stress conditions.
  • Identification of specific microRNAs regulated by high and low shear stress.
  • Review of existing literature on microRNA function in vascular physiology and pathology.

Main Results:

  • High shear stress induces atheroprotective miRs (e.g., miR-10a, miR-19a, miR-143/145).
  • Low shear stress induces pathological miRs (e.g., miR-21, miR-92a, miR-663) in endothelial cells.
  • MiR-155 exhibits context-dependent functions based on shear stress patterns.

Conclusions:

  • Shear stress-induced microRNA expression changes are critical for maintaining vascular homeostasis.
  • Dysregulation of microRNAs by altered blood flow contributes to cardiovascular disease.
  • Targeting microRNA pathways holds promise for future clinical applications in cardiovascular medicine.
