Abstract

Insights

Inhibitor of growth family member 4 (ING4) and JWA play key roles in melanoma angiogenesis. Their combined expression levels serve as important prognostic markers for melanoma patient survival and potential therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • Inhibitor of growth family member 4 (ING4) inhibits melanoma angiogenesis.
  • JWA suppresses melanoma cell metastasis.
  • Angiogenesis is critical for tumor metastasis, necessitating further study of ING4 and JWA roles and prognostic value.

Purpose of the Study:

  • Investigate the correlation between ING4 and JWA in melanoma angiogenesis.
  • Determine the prognostic value of ING4, JWA, and integrin-linked kinase (ILK) in melanoma patients.

Main Methods:

  • Western blot, tube-formation assays, and luciferase assays were employed.
  • JWA and ILK expression analyzed via tissue microarray in 175 melanoma biopsies.

Main Results:

  • ING4 promotes JWA expression and partially mediates ING4's regulation of endothelial cell growth and tube formation.
  • ING4 inhibits ILK-induced angiogenesis via JWA.
  • Reduced JWA or increased ILK expression correlates with decreased 5-year survival.
  • ING4/JWA/ILK expression levels are significant predictors of 5-year melanoma survival.

Conclusions:

  • JWA is crucial in ING4-regulated melanoma angiogenesis.
  • ING4, JWA, and ILK are promising prognostic markers for melanoma.
  • The ING4/JWA/ILK pathway presents potential anti-angiogenic therapeutic targets for melanoma.

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...

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...

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

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...
