Insights

Receptor tyrosine kinases (RTKs) normally control cell responses. In cancer, altered RTKs drive abnormal cell proliferation and evasion of growth controls, contributing to malignancy.

Area of Science:

  • Cellular biology
  • Molecular oncology
  • Signal transduction

Background:

  • Cells respond to external stimuli via receptor tyrosine kinases (RTKs).
  • RTK activation is tightly regulated in normal cells for environmental integration.
  • Tumors exhibit altered RTK signaling, enabling uncontrolled proliferation.

Purpose of the Study:

  • To review the role of receptor tyrosine kinases in cancer development.
  • To highlight alterations in RTK expression and signaling in malignancy.
  • To focus on RTKs as a major theme in breast cancer research.

Main Methods:

  • Review of scientific literature on RTKs and cancer.
  • Analysis of molecular alterations in RTK pathways.
  • Focus on signaling molecules downstream of RTKs.

Main Results:

  • Aberrant RTK expression and activation are hallmarks of cancer.
  • Dysregulated RTK signaling contributes to cancer cell proliferation and survival.
  • Altered downstream signaling molecules are critical in tumorigenesis.

Conclusions:

  • RTKs are crucial in normal cellular function and environmental response.
  • Molecular alterations in RTKs are key drivers of cancer.
  • Understanding RTK pathways is vital for breast cancer research and therapy.

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.

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...
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...
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...
