Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

2.6K
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...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Area of Science:

  • Cardiovascular Biology
  • Oncology
  • Biomarker Discovery

Background:

  • Circulating endothelial cells (CECs) are increasingly recognized for their potential as sensitive indicators of vascular injury and disease.
  • Elevated CEC counts are observed in various pathological conditions, including cardiovascular diseases and cancer.

Approach:

  • This review synthesizes recent research on the roles and importance of CECs in vascular-related diseases.
  • It highlights advancements in standardized detection methods, such as flow cytometry, for isolating and quantifying CECs.
  • The review also discusses the development of highly sensitive techniques for phenotyping rare cells.

Key Points:

  • CECs serve as indicators of disease severity, progression, and prognosis in conditions like acute myocardial infarction, heart failure, and cancer.
  • Increased CEC levels in cancer patients correlate with disease advancement, angiogenesis, and treatment response.
  • Standardization of CEC detection and advanced isolation techniques are paving the way for clinical applications.

Conclusions:

  • CECs are emerging biomarkers with significant clinical value for evaluating vascular injury.
  • Further research into CECs can deepen our understanding of endothelial cell contributions to vascular disorders.
