Insights

Angiotensin II (AngII) plays a role in cancer by influencing cell growth and blood vessel formation. Angiotensin I-converting enzyme (ACE) inhibitors and receptor blockers show potential in cancer treatment.

Area of Science:

  • Cardiovascular Science
  • Oncology
  • Molecular Biology

Background:

  • Angiotensin II (AngII) is a key regulator of blood pressure and cardiovascular homeostasis.
  • Emerging evidence links AngII to cell proliferation, angiogenesis, inflammation, and tissue remodeling, suggesting a role in cancer.
  • The Angiotensin I-converting enzyme (ACE) and its receptors are implicated in various cancer aspects.

Purpose of the Study:

  • To review the expression and function of ACE and AngII receptors in cancer.
  • To explore the role of AngII type 1 receptor (AT1R) and AngII type 2 receptor (AT2R) in tumor progression.
  • To overview intracellular signaling pathways activated by AT1R and AT2R in cancer.

Main Methods:

  • Literature review of experimental data on ACE inhibitors and AngII receptor antagonists.
  • Analysis of studies investigating AT1R and AT2R roles in tumor vascularization and metastasis.
  • Examination of signaling pathways in cancer, endothelial, and inflammatory cells.

Main Results:

  • ACE inhibitors and AT1R antagonists demonstrate beneficial effects on tumor progression, vascularization, and metastasis.
  • The AT2R subtype shows potential involvement in cancer development.
  • Specific intracellular signaling pathways associated with AT1R and AT2R activation are identified.

Conclusions:

  • The renin-angiotensin system, particularly AngII and its receptors, is significantly involved in cancer biology.
  • Targeting ACE and AngII receptors presents a promising therapeutic strategy for cancer treatment.
  • Further research into AT2R's role and detailed signaling mechanisms is warranted for comprehensive cancer therapy development.

Antihypertensive Drugs: Angiotensin II Receptor Blockers

In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...

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:

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...
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...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...
