Summary
T cell acute lymphoblastic leukemia (T-ALL) is a cancer affecting thymocytes. Activating NOTCH1 mutations are common, highlighting aberrant NOTCH1 signaling in T-ALL pathogenesis.
Area of Science:
- Hematology
- Oncology
- Molecular Biology
Background:
- T cell acute lymphoblastic leukemia (T-ALL) is an aggressive cancer of thymocytes, primarily affecting children and adolescents.
- T-ALL is characterized by genetic alterations that disrupt normal thymocyte development.
- The NOTCH1 pathway is frequently altered in T-ALL.
Purpose of the Study:
- To review and update recent findings on the molecular mechanisms of T-ALL.
- To emphasize the role of aberrant NOTCH1 signaling in T-ALL pathogenesis.
Main Methods:
- Literature review of molecular mechanisms in T-ALL.
- Focus on genetic alterations, particularly NOTCH1 mutations.
Main Results:
- Activating point mutations in NOTCH1 are identified in over 50% of T-ALL cases.
- Aberrant NOTCH1 signaling is a central mechanism in T-ALL development.
Conclusions:
- NOTCH1 signaling is a critical oncogenic driver in T-ALL.
- Understanding NOTCH1's role is key for T-ALL treatment strategies.

03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

01:12Role 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...

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
