Angiogenesis, or new blood vessel formation, is crucial in development and disease. This review explores novel therapeutic strategies targeting angiogenesis and its role in tumor growth.

Area of Science:

  • Molecular Biology
  • Oncology
  • Vascular Biology

Background:

  • Angiogenesis is vital for embryogenesis, vascular remodeling, and pathological conditions like tumor development.
  • While blood vessel sprouting is primary, mechanisms like bone marrow-derived cell recruitment also contribute to angiogenesis.
  • Vascular Endothelial Growth Factor (VEGF) family members and their receptors are key mediators of these processes.

Purpose of the Study:

  • To review recent findings on angiogenesis, focusing on its role in cancer.
  • To explore novel therapeutic approaches targeting angiogenic pathways.
  • To discuss the implications of VEGF receptor expression in non-endothelial cells, including tumor cells.

Main Methods:

  • Literature review of recent studies on angiogenesis.

  • Analysis of the role of VEGF family and its receptors in cancer.
  • Evaluation of emerging therapeutic strategies targeting angiogenesis.

    • Main Results:

    • VEGF receptors, initially thought to be endothelial-specific, are found on tumor cells.
    • Altered VEGF receptor expression on tumor cells may promote cancer growth via autocrine loops.
    • Other angiogenic factors and receptors are also detected on tumor cells, suggesting therapeutic potential.

    Conclusions:

    • VEGF receptor expression in tumor cells presents a potential mechanism for angiogenesis-independent growth.
    • Tumor cell-expressed angiogenic molecules represent promising therapeutic targets for cancer treatment.
    • Future research focuses on developing mechanism-based therapies for various cancers by targeting angiogenesis.
