Insights

Small regulatory ribonucleic acids (RNAs) are linked to diseases like cancer. These microRNAs (miRNAs) show potential as stable diagnostic and prognostic markers for gastrointestinal malignancies, paving the way for targeted therapies.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Genetics

Background:

  • Small regulatory ribonucleic acids (RNAs) are increasingly associated with common diseases, including cancer, heart disease, diabetes, and inflammation.
  • Over 5,000 publications on PubMed highlight the growing research interest in these molecules.
  • Specific pathways generate distinct RNA classes, converging in RNA interference pathways.

Purpose of the Study:

  • To investigate the role and potential applications of microRNAs (miRNAs) in gastrointestinal malignancies.
  • To explore the diagnostic and prognostic value of miRNAs derived from archived tissue biopsies.
  • To assess the potential of small RNAs in developing targeted cancer therapies.

Main Methods:

  • Analysis of microRNA deregulation in various gastrointestinal malignancies.
  • Evaluation of miRNA stability and resistance to RNAse degradation in archived tissue samples.
  • Exploration of miRNA interactions with transcription factors and signaling pathways.

Main Results:

  • MicroRNAs are deregulated in gastrointestinal malignancies, with levels varying by malignancy type and disease stage.
  • MicroRNAs function as either tumor suppressors or oncogenes within regulatory loops.
  • Extracted miRNAs from archived biopsies are stable and resistant to degradation, indicating their utility as biomarkers.

Conclusions:

  • MicroRNAs are significant players in gastrointestinal cancer pathogenesis.
  • Stable miRNAs from archival tissues serve as effective diagnostic, prognostic, and molecular markers.
  • The unique properties of small RNAs offer promise for future targeted cancer therapies.

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...

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

siRNA - Small Interfering RNAs

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the ATP-dependent...
Ribozymes02:47

Ribozymes

The term ribozyme is used for RNA that can act as an enzyme. Ribozymes are mainly found in selected viruses, bacteria, plant organelles, and lower eukaryotes. Ribozymes were first discovered in 1982 when Tom Cech’s laboratory observed Group I introns acting as enzymes. This was shortly followed by the discovery of another ribozyme, Ribonulcease P, by Sid Altman’s laboratory. Both Cech and Altman received the Nobel Prize in chemistry in 1989 for their work on ribozymes.
Ribozymes can be...
RNA Interference01:23

RNA Interference

RNA interference (RNAi) is a process in which a small non-coding RNA molecule blocks the post-transcriptional expression of a gene by binding to its messenger RNA (mRNA) and preventing the protein from being translated.
This process occurs naturally in cells, often through the activity of genomically-encoded microRNAs. Researchers can take advantage of this mechanism by introducing synthetic RNAs to deactivate specific genes for research or therapeutic purposes. For example, RNAi could be used...
