Insights

Mitogen-activated protein kinase (MAP kinase) pathways are crucial signaling cascades. This review highlights how proto-oncogenes and oncogenes regulate and are targeted by these essential MAP kinase pathways.

Area of Science:

  • Cellular signaling pathways
  • Molecular biology
  • Oncology

Background:

  • Mitogen-activated protein kinase (MAP kinase) pathways are central to cellular responses.
  • These pathways are activated by diverse extracellular signals.
  • Dysregulation of signaling pathways is implicated in cancer development.

Purpose of the Study:

  • To review the intricate relationship between MAP kinase pathways and proteins encoded by proto-oncogenes and oncogenes.
  • To elucidate the regulatory roles and target interactions within this signaling network.

Main Methods:

  • Literature review of existing research on MAP kinase signaling.
  • Analysis of studies investigating proto-oncogene and oncogene involvement in MAP kinase pathways.
  • Synthesis of evidence on regulatory mechanisms and target interactions.

Main Results:

  • Accumulating evidence demonstrates that proto-oncogene and oncogene proteins are integral to MAP kinase pathway regulation.
  • These proteins act as either regulators or targets within the MAP kinase cascade.
  • Specific examples of oncogenic proteins influencing MAP kinase signaling are discussed.

Conclusions:

  • Proto-oncogenes and oncogenes play significant roles in modulating MAP kinase pathway activity.
  • Understanding these interactions is critical for comprehending cancer biology.
  • Targeting these pathways offers potential therapeutic strategies in oncology.

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.

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
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...
