Insights

Posttranslational modifications (PTMs) regulate protein function and are crucial in cancer. This review explores how PTMs reprogram gastrointestinal cancer stemness, offering new therapeutic targets.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cancer Biology

Background:

  • Posttranslational modifications (PTMs) are vital protein regulatory mechanisms.
  • PTMs influence proteome diversity and complex biological processes.
  • PTMs are increasingly recognized for their role in cancer development, recurrence, and therapy resistance.

Purpose of the Study:

  • To review the latest findings on protein PTMs in reprogramming gastrointestinal (GI) cancer stemness.
  • To elucidate the mechanisms by which PTMs maintain cancer stemness and drive therapeutic resistance.
  • To highlight the clinical relevance of PTMs as biomarkers and therapeutic targets in GI malignancies.

Main Methods:

  • Literature review focusing on recent advancements in PTMs and cancer stemness.
  • Analysis of PTM profiles in various tumor types, particularly GI cancers.
  • Examination of signaling pathways involved in PTM-mediated stemness regulation.

Main Results:

  • PTMs play a significant role in modulating cancer stemness across different tumor types.
  • Aberrant PTMs are implicated in neoplastic transformation, tumor recurrence, and resistance to oncotherapy.
  • Specific PTMs are identified as key regulators of gastrointestinal cancer stem cell self-renewal and differentiation.

Conclusions:

  • Understanding abnormal PTMs in GI cancer offers opportunities to target cancer stem cells.
  • PTMs represent promising biomarkers for GI cancer diagnosis and prognosis.
  • Targeting PTMs presents a novel therapeutic strategy for GI malignancies.

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...

Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

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.
The mTOR pathway or the...

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...
