Insights

The Ron receptor tyrosine kinase promotes tumor growth and is overexpressed in human cancers like breast and bladder cancer. Blocking Ron activity offers a promising therapeutic strategy for targeted cancer treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Signal Transduction

Background:

  • The Ron receptor tyrosine kinase (RTK) plays a significant role in tumorigenesis.
  • Ron activation triggers downstream signaling pathways, including MAPK, PI3K, and beta-catenin.
  • Increased Ron activity is linked to increased tumorigenesis in epithelial cancers.

Purpose of the Study:

  • To review the oncogenic potential of the Ron receptor.
  • To highlight the correlation between Ron overexpression and poor clinical outcomes in breast and bladder cancers.
  • To discuss the therapeutic implications of targeting Ron activity.

Main Methods:

  • Review of experimental models of mammalian tumorigenesis.
  • Analysis of human tumor biology data regarding Ron receptor expression.
  • Evaluation of experimental approaches to inhibit Ron activity.

Main Results:

  • Ron receptor tyrosine kinase is increasingly recognized for its tumorigenic potential.
  • Overexpression and overactivation of Ron are observed in numerous human tumors.
  • Ron overexpression correlates with worse clinical outcomes in breast and bladder cancers.

Conclusions:

  • Evidence supports Ron's role as an oncogene in human cancer.
  • Targeting Ron receptor activity presents a promising strategy for future clinical cancer trials.

Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...
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...
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.

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...
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
