Cancer Stem Cells and Tumor Maintenance02:40

Cancer Stem Cells and Tumor Maintenance

6.3K
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...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.6K
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...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

4.4K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Multipotency of Hematopoietic Stem Cells01:19

Multipotency of Hematopoietic Stem Cells

4.1K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Somatic to iPS Cell Reprogramming01:29

Somatic to iPS Cell Reprogramming

2.8K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Area of Science:

  • Oncology
  • Stem Cell Biology
  • Molecular Biology

Background:

  • Cancer cells exhibit similarities to embryonic stem cells (ESCs), including shared gene expression signatures.
  • ESC-specific genes present potential targets for cancer diagnosis and therapy due to their absence in most adult tissues.
  • Identifying key embryonic stem cell factors driving the cancer phenotype is crucial for developing targeted treatments.

Purpose of the Study:

  • To review the current understanding of the SALL4 gene in relation to stem cells, development, and cancer.
  • To explore a SALL4-based strategy for classifying and targeting cancers.
  • To highlight unanswered questions regarding SALL4's molecular functions in cell fate regulation.

Main Methods:

  • Literature review of SALL4 research in stem cells, development, and cancer.
  • Analysis of SALL4's role in establishing links between embryonic stem cells and cancer.
  • Synthesis of knowledge on SALL4's function and potential therapeutic applications.

Main Results:

  • SALL4 is identified as a key gene connecting embryonic stem cells and cancer phenotypes.
  • Over 300 publications demonstrate SALL4's involvement in stem cells, development, and various cancers.
  • A SALL4-based approach for cancer classification and targeting is proposed.

Conclusions:

  • SALL4 plays a significant role in linking embryonic stem cells and cancer.
  • Further research into SALL4's molecular mechanisms is essential for developing targeted cancer therapies.
  • Understanding SALL4's regulation of cell fate holds promise for future cancer treatment strategies.
