Insights

New enzyme targets show promise for inhibiting tumor growth and metastasis. Inhibiting heparanase, NADPH oxidase, lysyl oxidase (LOX), and angiotensin-converting enzyme (ACE) offers potential new anticancer therapies.

Area of Science:

  • Oncology
  • Biochemistry
  • Pharmacology

Background:

  • Angiogenesis is a key target for cancer therapy, with current treatments focusing on VEGF/VEGFR pathways.
  • Approved anti-angiogenic therapies include monoclonal antibodies and multikinase inhibitors.
  • Emerging evidence highlights the role of specific enzymes in tumor-driven angiogenesis.

Purpose of the Study:

  • To review current knowledge on enzymatic targets in tumor-driven angiogenesis.
  • To explore the potential clinical applications of modulating these enzymatic targets.
  • To identify promising novel therapeutic strategies for cancer treatment.

Main Methods:

  • Literature review of preclinical and clinical studies.
  • Analysis of enzymatic pathways involved in angiogenesis.
  • Evaluation of the efficacy and suitability of enzyme inhibitors for clinical application.

Main Results:

  • Metalloproteinase and nitric oxide synthase inhibitors have shown limited clinical success.
  • Early clinical studies of heparanase, nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, lysyl oxidase (LOX), and angiotensin-converting enzyme (ACE) inhibitors show promising results.
  • These enzymes represent potential targets for novel anticancer therapies.

Conclusions:

  • Heparanase, NADPH oxidase, LOX, and ACE are identified as promising enzymatic targets for anticancer therapy.
  • Modulation of these enzymes could lead to more effective anti-angiogenic treatments.
  • Further clinical investigation is warranted to validate these findings.

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...

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...

Mitogens and the Cell Cycle02:38

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

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:
