Insights

The extracellular-signal-regulated kinases (ERK MAPK) pathway is crucial for cell proliferation and is implicated in colorectal cancer progression. Targeting ERK MAPK offers a potential therapeutic strategy for this disease.

Area of Science:

  • Molecular Biology
  • Oncology
  • Signal Transduction

Background:

  • Mitogen-activated protein kinases (MAPK) comprise three major subfamilies: ERK MAPK, JNK/SAPK, and MAPK14.
  • The ERK MAPK pathway is vital for cell proliferation and is downstream of growth-factor receptors like epidermal growth factor receptor (EGFR).
  • EGFR overexpression and activation are common in colorectal cancer, suggesting a role for ERK MAPK in its progression.

Purpose of the Study:

  • To review the ERK MAPK signal-transduction pathway.
  • To examine the consequences of ERK MAPK dysregulation in colorectal cancer.
  • To discuss the potential of targeting ERK MAPK for colorectal cancer treatment.

Main Methods:

  • Literature review of scientific articles and clinical studies.
  • Analysis of signal-transduction pathways.
  • Examination of molecular mechanisms in cancer progression.

Main Results:

  • The ERK MAPK pathway plays a significant role in cell proliferation.
  • Dysregulation of ERK MAPK is linked to colorectal cancer progression.
  • ERK MAPK represents a promising molecular target for colorectal cancer therapy.

Conclusions:

  • Targeting the ERK MAPK pathway is a potential therapeutic approach for colorectal cancer.
  • Further clinical assessment of ERK MAPK-targeted agents is necessary.
  • Understanding ERK MAPK signaling is key to developing effective cancer treatments.

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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 Pathways01:19

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...
