Insights

Impaired deactivation of receptor tyrosine kinases (RTKs) can drive cancer. Understanding RTK signaling inhibition is key for developing new tumor markers and therapies for cancer progression.

Area of Science:

  • Molecular biology
  • Cellular signaling
  • Oncology

Background:

  • Trophic factors regulate cell physiology via receptor tyrosine kinases (RTKs).
  • RTK overactivation is linked to cancer development.
  • Emerging evidence suggests impaired RTK deactivation also contributes to tumor formation.

Purpose of the Study:

  • To review mechanisms of RTK signaling inhibition.
  • To discuss the role of RTK deactivation defects in cancer.
  • To explore the potential of RTK signaling inhibitors as tumor suppressors and markers.

Main Methods:

  • Literature review of RTK signaling pathways.
  • Analysis of studies on RTK deactivation mechanisms.
  • Synthesis of evidence linking RTK deregulation to cancer.

Main Results:

  • Physiological RTK signaling attenuation involves specific molecular mechanisms.
  • Dysregulation of these inhibitory mechanisms is implicated in various cancers.
  • Defects in RTK down-regulation can promote tumor growth and progression.

Conclusions:

  • Molecular determinants of RTK signaling inhibition are crucial for cellular homeostasis.
  • Impaired RTK deactivation represents a significant mechanism in tumorigenesis.
  • Targeting RTK signaling inhibition pathways offers potential for novel cancer diagnostics and therapeutics.

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...
Enzyme-linked Receptors01:00

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
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...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
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...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:
