Insights

Inactivating the adenomatous polyposis coli (APC) gene is common in colorectal cancer. New research shows targeting c-Myc in mice with APC defects significantly reduces cancer-related changes.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Adenomatous polyposis coli (APC) tumor suppressor gene inactivation is a key event in most colorectal cancers.
  • The proto-oncogene c-MYC is implicated in APC-deficient cancers, but its precise role in vivo remains unclear.

Purpose of the Study:

  • To investigate the in vivo significance of c-MYC's role in intestinal epithelial cells with APC defects.
  • To evaluate the impact of targeted c-Myc inactivation on the phenotypic and transcriptional alterations associated with APC deficiency.

Main Methods:

  • Utilized a murine model with targeted c-Myc inactivation in intestinal epithelium.
  • Analyzed phenotypical and transcriptional changes in Apc-deficient intestinal epithelium following c-Myc manipulation.

Main Results:

  • Targeted inactivation of c-Myc in murine intestinal epithelium markedly inhibited phenotypic changes characteristic of Apc deficiency.
  • Transcriptional alterations typically observed in Apc-deficient intestinal cells were also significantly suppressed.

Conclusions:

  • c-Myc plays a critical role in driving the progression of Apc-deficient intestinal epithelium.
  • While these findings highlight c-Myc's importance, further research is needed to fully elucidate its position as a pre-eminent beta-catenin-regulated gene.

Anaphase Promoting Complex00:50

Anaphase Promoting Complex

The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
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...
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...
Separation of Sister Chromatids02:17

Separation of Sister Chromatids

At the transition from prophase to metaphase, there is a reduction in cohesion along the chromosomal arms, resulting in the resolution of sister chromatids. However, residual cohesin connections remain to hold the sister chromatids together until the transition from metaphase to anaphase. The residual connection prevents any premature separation of sister chromatids, blocking the risks of aneuploidy within the daughter cells.
At the onset of anaphase, separase, a proteolytic enzyme, is...
M-Cdk Drives Transition Into Mitosis02:15

M-Cdk Drives Transition Into Mitosis

Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
M cyclin...
