Insights

A novel long non-coding RNA, lncRNA-ATB, promotes cancer metastasis by activating epithelial-mesenchymal transition and stabilizing IL-11 mRNA. This discovery reveals new therapeutic targets for inhibiting cancer spread.

Area of Science:

  • Molecular Biology
  • Cancer Research
  • Cell Signaling

Background:

  • Transforming Growth Factor-beta (TGF-β) signaling is a key regulator of cancer metastasis.
  • Understanding the molecular mechanisms driving metastasis is crucial for developing effective therapies.

Purpose of the Study:

  • To identify novel genes and pathways involved in TGF-β-induced metastasis.
  • To elucidate the role of long non-coding RNAs (lncRNAs) in cancer progression.

Main Methods:

  • Analysis of TGF-β-induced gene expression.
  • Investigation of lncRNA function using molecular and cellular assays.
  • Validation of lncRNA-ATB's role in epithelial-mesenchymal transition (EMT) and cancer cell colonization.

Main Results:

  • Discovery of a novel TGF-β-induced lncRNA, lncRNA-ATB.
  • lncRNA-ATB promotes EMT by sequestering microRNAs (miR-200s).
  • lncRNA-ATB stabilizes Interleukin-11 (IL-11) mRNA, enhancing cancer cell colonization.

Conclusions:

  • lncRNA-ATB is a critical mediator of both early and late stages of cancer metastasis.
  • Targeting lncRNA-ATB may offer a novel therapeutic strategy for inhibiting cancer spread.

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...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

Types of RNA01:20

Types of RNA

Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
