Insights

Non-coding RNAs (ncRNAs) regulate the Notch signaling pathway, impacting cancer hallmarks like proliferation and metastasis. Understanding this interaction is key for developing novel cancer therapies.

Area of Science:

  • Molecular Biology
  • Genetics
  • Oncology

Background:

  • Cancer remains a leading cause of death globally, necessitating innovative therapeutic strategies.
  • Aberrant gene expression in tumorigenesis highlights the importance of targeting regulatory signaling pathways.
  • The Notch signaling pathway plays a crucial role in cellular functions and cancer progression, including proliferation, apoptosis, invasion, metastasis, epithelial-to-mesenchymal transition (EMT), angiogenesis, and immune evasion.

Purpose of the Study:

  • To review the critical role of non-coding RNAs (ncRNAs) in regulating the Notch signaling pathway.
  • To explore how ncRNAs influence key cancer hallmarks.
  • To discuss the implications of ncRNA-Notch pathway interactions in cancer therapy and resistance.

Main Methods:

  • Literature review focusing on ncRNAs (microRNAs and long non-coding RNAs) and their interaction with the Notch pathway.
  • Analysis of studies investigating the role of ncRNAs in cancer hallmarks.
  • Examination of evidence linking ncRNA-mediated Notch regulation to therapeutic resistance.

Main Results:

  • ncRNAs, including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), are key regulators of the Notch signaling pathway.
  • Dysregulation of ncRNAs impacts various cancer hallmarks such as proliferation, apoptosis, autophagy, EMT, invasion, and metastasis.
  • ncRNAs influence cellular responses to chemo- and radiotherapy by modulating Notch signaling, contributing to therapeutic resistance.

Conclusions:

  • ncRNAs are significant modulators of the Notch pathway in cancer.
  • Targeting ncRNA-mediated regulation of Notch signaling presents a promising avenue for overcoming therapeutic resistance and improving cancer treatment outcomes.
  • Further research into ncRNA-Notch interactions is essential for developing effective cancer therapies.

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 Renewal01:12

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...

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

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...

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...
