Summary
The Wingless/Integrated (Wnt) pathway integrates with RAS-RAF-MAPK and PI3K-AKT-mTOR signaling to drive colorectal cancer. Understanding this crosstalk reveals new therapeutic strategies for cancer treatment.
Area of Science:
- Molecular Biology
- Cancer Biology
- Developmental Biology
Background:
- The Wingless/Integrated (Wnt)/β-catenin signaling pathway is crucial for embryonic development and tissue homeostasis.
- Aberrant Wnt signaling drives colorectal cancer initiation, progression, and therapeutic resistance.
- Wnt signaling acts as an integrative hub, interacting with RAS-RAF-MAPK and PI3K-AKT-mTOR pathways.
Purpose of the Study:
- To synthesize mechanistic and clinical insights into the crosstalk between Wnt, RAS-RAF-MAPK, and PI3K-AKT-mTOR pathways.
- To emphasize the role of these interactions in colorectal cancer.
- To explore developmental paradigms and therapeutic strategies related to Wnt signaling networks.
Main Methods:
- Literature review synthesizing current mechanistic and clinical insights.
- Integration of developmental paradigms from Xenopus embryogenesis.
- Examination of emerging therapeutic strategies.
Main Results:
- Wnt, RAS-RAF-MAPK, and PI3K-AKT-mTOR pathways converge at multiple molecular levels.
- These interactions regulate β-catenin stability, transcription, cell adhesion, and metabolism, generating oncogenic phenotypes.
- Developmental processes like body axis formation are governed by Wnt signaling.
Conclusions:
- Wnt signaling is a central integrator of developmental and oncogenic programs.
- Signaling network crosstalk explains oncogenic phenotypes not attributable to single pathways.
- Understanding Wnt-centered networks informs novel combinatorial therapies and drug delivery systems for cancer.

01:41Non-Canonical Wnt Signaling Pathways
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

02:54Canonical Wnt Signaling Pathway
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which results in tumor...

01:19Interactions 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...

03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
