Insights

Loss of the adenomatous polyposis coli (APC) gene in colorectal cancer deregulates TCF/LEF targets, especially c-MYC. Further c-MYC deregulation drives tumor progression, offering therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Loss of the adenomatous polyposis coli (APC) gene is a key event in colorectal cancer development.
  • APC loss leads to rapid dysregulation of TCF/LEF transcription factor target genes.
  • The transcription factor c-MYC is a critical downstream target of this pathway.

Purpose of the Study:

  • To review the interplay between Wnt and c-MYC signaling in intestinal homeostasis and colorectal cancer.
  • To discuss how c-MYC deregulation contributes to colorectal tumor progression.
  • To explore potential therapeutic strategies targeting c-MYC in colorectal carcinogenesis.

Main Methods:

  • Literature review of Wnt/APC/c-MYC signaling pathways.
  • Analysis of current research on c-MYC's role in colorectal cancer progression.
  • Synthesis of data on therapeutic targeting of c-MYC.

Main Results:

  • APC loss critically impacts Wnt signaling, leading to c-MYC overexpression.
  • Elevated c-MYC levels are implicated in driving colorectal tumor progression and metastasis.
  • Understanding c-MYC regulation provides insights into novel therapeutic approaches.

Conclusions:

  • The Wnt/c-MYC axis is central to colorectal cancer initiation and progression.
  • Targeting c-MYC represents a promising strategy for colorectal cancer treatment.
  • Further research into c-MYC regulatory mechanisms is crucial for effective therapeutic development.

Canonical Wnt Signaling Pathway02:54

Canonical 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...

Non-Canonical Wnt Signaling Pathways01:41

Non-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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
Somatic cells are...
