Insights

CD147 promotes melanoma metastasis and angiogenesis. Silencing CD147 in B16 melanoma cells reduced metastasis and vascular endothelial growth factor (VEGF) expression, indicating CD147

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Oncology

Background:

  • CD147 is frequently overexpressed in various cancer cells.
  • Its association with tumor invasiveness and metastasis is linked to the induction of matrix metalloproteinases (MMPs).
  • However, MMP-2 and MMP-9 expression in the B16 melanoma model is independent of CD147.

Purpose of the Study:

  • To investigate the specific role of CD147 in metastasis and angiogenesis within the B16 melanoma murine model.
  • To determine if CD147's pro-metastatic effects are mediated through MMP induction in this context.

Main Methods:

  • Stable knockdown of CD147 expression in B16 melanoma cells.
  • Assessment of metastasis formation to draining lymph nodes in vivo.
  • Evaluation of vascular endothelial growth factor (VEGF) expression and blood vessel formation (angiogenesis).

Main Results:

  • CD147 knockdown significantly reduced the metastatic potential of B16 melanoma cells to lymph nodes.
  • Silencing CD147 led to decreased in vivo VEGF expression.
  • Reduced blood vessel formation was observed in CD147-knockdown tumors.

Conclusions:

  • In the B16 melanoma model, CD147 promotes metastasis.
  • CD147 facilitates metastasis primarily through the induction of angiogenesis, independent of MMP activity.
  • Targeting CD147 may offer a therapeutic strategy to inhibit melanoma metastasis by disrupting angiogenesis.

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...
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...
Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
