Abstract

Insights

Nucleoside diphosphate kinase (NDPK) plays a key role in breast cancer angiogenesis and metastasis. Lower NDPK levels correlate with increased tumor growth and spread, suggesting it as a therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Neo-angiogenesis is crucial for breast tumor growth, migration, and metastasis.
  • Inhibiting angiogenesis is a significant therapeutic strategy.
  • Bevacizumab and other antiangiogenic treatments show clinical promise.

Purpose of the Study:

  • To discuss the biological aspects of breast cancer angiogenesis.
  • To highlight nucleoside diphosphate kinase (NDPK) as a key molecule in this process.

Main Methods:

  • Review of clinical and experimental trials.
  • Analysis of NDPK's role in cellular signal transduction.

Main Results:

  • NDPK is inversely related to breast cancer metastasis and angiogenesis.
  • Nm23-H1/NDP kinase interacts with proteins involved in angiogenesis and tumorigenesis.

Conclusions:

  • NDPK inhibition reduces the metastatic potential of cancer cells.
  • NDPK downregulates extracellular signal-regulated kinase (ERK)/MAPK activation in response to angiogenic signals.

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...

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
