Insights

Mastermind-like (MAML) proteins are crucial co-activators in Notch signaling, essential for cell fate determination. This review highlights their roles in normal development and human cancers, underscoring their significance in oncogenesis.

Area of Science:

  • Molecular Biology
  • Developmental Biology
  • Cancer Biology

Background:

  • Notch signaling regulates cell fate through cell-cell interactions.
  • Mastermind-like (MAML) proteins act as transcriptional co-activators.
  • MAML proteins partner with Notch and CSL to drive gene transcription.

Purpose of the Study:

  • To review the current understanding of MAML protein functions in Notch signaling.
  • To explore the involvement of MAML genes in human cancers.
  • To consolidate evidence on MAML's role in development and oncogenesis.

Main Methods:

  • Literature review of biochemical and functional studies.
  • Analysis of MAML gene involvement in cellular processes.
  • Examination of MAML's role in oncogenic pathways.

Main Results:

  • MAML proteins are essential components of the Notch signaling pathway.
  • Evidence links MAML genes to the regulation of cell fate determination.
  • MAML proteins are implicated in the development of certain human cancers.

Conclusions:

  • MAML genes are critical regulators within the Notch pathway.
  • MAML proteins play significant roles in both normal development and cancer.
  • Further research into MAML's function is warranted for therapeutic insights.

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...
Notch Signaling Pathway03:14

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 until 1985...
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...

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...
