Insights

The MET proto-oncogene regulates invasive growth, crucial for development and healing. Aberrant MET signaling drives cancer metastasis, making it a key therapeutic target for novel inhibitors and antibodies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • The MET proto-oncogene encodes a tyrosine kinase receptor for Hepatocyte Growth Factor (HGF).
  • MET signaling regulates invasive growth, a process involving cell proliferation, extracellular matrix invasion, and apoptosis resistance.
  • Physiological roles include embryonic development, wound healing, and tissue regeneration.

Purpose of the Study:

  • To investigate the role of MET proto-oncogene in pathological invasive growth and metastasis.
  • To explore MET as a therapeutic target for cancer treatment.
  • To understand the interplay between MET and the protease network for effective inhibition strategies.

Main Methods:

  • Analysis of MET proto-oncogene expression and mutations in tumors.
  • Investigating small molecule kinase inhibitors targeting MET.
  • Developing inhibitory antibodies against MET and its ligand HGF.
  • Studying the interaction of MET with the protease network.

Main Results:

  • MET overexpression and/or mutations are associated with pathological invasive growth and metastasis in various tumors.
  • MET signaling sustains tumor progression and is a critical factor in metastasis.
  • Targeting MET with kinase inhibitors or antibodies shows promise for cancer therapy.
  • Exploiting the interplay between MET and proteases offers new avenues for therapeutic intervention.

Conclusions:

  • The MET proto-oncogene is a critical regulator of invasive growth, with dysregulation driving cancer metastasis.
  • Targeting MET and its signaling pathway presents a promising strategy for developing novel anti-cancer therapies.
  • Understanding the MET-protease network interactions is key to achieving effective inhibition of pathological invasive growth.

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...
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.
There are several types of targeted therapies against specific...
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...

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...
Cancer-Critical Genes I: Proto-oncogenes01:33

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
