Abstract

Insights

Targeting tumor angiogenesis with vascular endothelial growth factor (VEGF) inhibitors has improved cancer treatment. Further research into VEGF signaling mechanisms and predictive biomarkers is crucial for overcoming resistance and non-response to anti-VEGF therapy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Therapeutics

Background:

  • Angiogenesis, the formation of new blood vessels, is a critical process in tumor growth and has been a target for cancer treatment for decades.
  • Vascular Endothelial Growth Factor (VEGF) has been identified as a key mediator of tumor angiogenesis, leading to the development of targeted anti-VEGF therapies.

Purpose of the Study:

  • To review recent data on VEGF signaling in cancer development.
  • To analyze the response of various cancers to anti-VEGF treatments.
  • To explore reasons for therapy failure and identify potential predictive biomarkers for treatment response.

Main Methods:

  • Systematic literature review of PubMed and MEDLINE databases.
  • Analysis of articles published between 2000 and 2011.
  • Focus on molecular mechanisms, clinical responses, and therapeutic challenges related to VEGF inhibition.

Main Results:

  • Anti-VEGF therapy has shown success in improving outcomes for several cancer types.
  • Variability in patient response, including development of resistance and lack of initial response, has been observed.
  • Understanding VEGF signaling pathways is key to improving therapeutic efficacy.

Conclusions:

  • Despite advancements, significant challenges remain in anti-VEGF therapy.
  • Further investigation into the molecular mechanisms of VEGF signaling is necessary.
  • Development of predictive biomarkers is essential for optimizing patient selection and treatment strategies for anti-VEGF therapies.

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.

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...
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...
Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
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...
