Insights

This review explores how Notch signaling, a conserved biological pathway, influences cell apoptosis. It details CSL-dependent and independent pathways, offering new insights into cell death mechanisms.

Area of Science:

  • Cellular Biology
  • Molecular Mechanisms
  • Developmental Biology

Background:

  • Apoptosis is a fundamental biological process involving intricate molecular signaling pathways.
  • Notch signaling is an evolutionarily conserved pathway crucial for development, tissue homeostasis, and immune regulation.

Purpose of the Study:

  • To review recent advances in understanding the roles of CSL-dependent and independent Notch signaling in cell apoptosis.
  • To elucidate the molecular mechanisms underlying Notch-mediated apoptosis.

Main Methods:

  • Literature review focusing on novel research in Notch signaling and apoptosis.
  • Analysis of molecular mechanisms involving CSL-dependent and CSL-independent pathways.
  • Examination of key signaling molecules such as CSL, NIC, Hes-1, PTEN, AKT, mTOR, and mTORC2.

Main Results:

  • CSL-dependent Notch signaling regulates apoptosis via the Hes-1-PTEN-AKT-mTOR pathway.
  • CSL-independent Notch signaling potentially mediates apoptosis through the NIC-mTORC2-AKT-mTOR pathway.
  • These distinct pathways offer new perspectives on the regulation of programmed cell death.

Conclusions:

  • Notch signaling plays a significant role in regulating cell apoptosis through both CSL-dependent and independent mechanisms.
  • Understanding these pathways provides novel insights into apoptotic mechanisms and potential therapeutic targets.

Notch 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...

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...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size...
