Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

5.1K
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

4.0K
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...

Protein Kinases and Phosphatases02:54

Protein Kinases and Phosphatases

13.9K
Proteins undergo chemical modifications that trigger changes in the charge, structure, and conformation of the proteins. Phosphorylation, acetylation, glycosylation, nitrosylation, ubiquitination, lipidation, methylation, and proteolysis are various protein modifications that regulate protein activity. Such modifications are usually enzyme-driven.
Protein kinases
Many proteins in the cell are regulated by phosphorylation, the addition of a phosphate group. A family of enzymes called kinases...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells01:18

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells

3.8K
A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.7K
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...

Cancer-Critical Genes II: Tumor Suppressor Genes01:05

Cancer-Critical Genes II: Tumor Suppressor Genes

8.4K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Cancer stem cells (CSCs) drive tumor initiation, progression, and therapy resistance.
  • Kinase signaling in CSCs is well-studied, but the role of phosphatases remains poorly understood.
  • Many phosphatases are now druggable targets, presenting new therapeutic avenues.

Purpose of the Study:

  • To review the current knowledge on phosphatases in CSCs.
  • To highlight the functional roles of phosphatases in CSC self-renewal, progression, and resistance.
  • To discuss the therapeutic potential of targeting CSC phosphatases.

Main Methods:

  • Literature review of fundamental and applied research on phosphatases in CSCs.
  • Focus on signaling pathways, self-renewal, cancer progression, and therapy resistance.
  • Emphasis on hematological cancers and glioblastoma.

Main Results:

  • Phosphatases play a critical, yet underappreciated, role in regulating CSC signaling pathways.
  • Dysregulation of phosphatases contributes to CSC self-renewal, cancer progression, and resistance to therapy.
  • Targeting phosphatases in CSCs shows promise for combination therapies.

Conclusions:

  • Phosphatases are key regulators of CSC functions and therapeutic resistance.
  • Further investigation into CSC phosphatases is warranted for novel cancer treatment strategies.
  • Targeting CSC phosphatases offers potential for innovative combination therapies in oncology.
