Abstract

Insights

Notch1 protein influences Hes1, c-Myc, and Jagged2 expression in small cell lung carcinoma (SCLC). This finding enhances understanding of lung cancer development and potential therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • The Notch signaling pathway plays complex roles in human cancers, acting as either tumor-promoting or anti-proliferative.
  • Notch signaling's impact on carcinogenesis is often tissue-specific.

Purpose of the Study:

  • To investigate the relationship between Notch1 protein expression and related proteins (Hes1, c-Myc, Jagged1, Jagged2) in lung cancer cells.

Main Methods:

  • Detection of Notch1 and related proteins in lung cancer cell lines and patient tissues.
  • Utilized small interfering RNA (siRNA) to down-regulate Notch1 in small cell lung carcinoma (SCLC) cells.
  • Transfected venus Notch1 intracellular domain (v.NICD) plasmid into human SCLC lines.

Main Results:

  • Notch1 expression was found to affect Hes1, c-Myc, and Jagged2 expression in SCLC.

Conclusions:

  • A significant association exists between Notch1 protein expression and the expression of Hes1, c-Myc, and Jagged2 proteins.
  • These findings may contribute to a deeper understanding of SCLC tumorigenesis.

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...

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...

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...
