Experimental RNAi

6.5K
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

13.4K
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...

RNA Interference

24.3K
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...

Area of Science:

  • Epigenetics and Gene Regulation
  • Molecular Biology
  • Genomics

Background:

  • Noncoding RNA (ncRNA) transcripts are increasingly recognized for their crucial role in gene expression regulation.
  • ncRNAs target specific genomic loci, influencing epigenetic modifications and gene silencing.
  • Classical examples include X-chromosome inactivation and genomic imprinting, but ncRNA influence extends broadly across the metazoan genome.

Purpose of the Study:

  • To elucidate the mechanisms by which ncRNAs guide epigenetic silencing complexes to specific genomic sites.
  • To explore the potential of targeting ncRNAs for therapeutic applications, particularly for diseases requiring gene activation.

Main Methods:

  • Investigation of ncRNA-mediated epigenetic regulation in a subset of genes.
  • Analysis of mechanisms underlying ncRNA-guided epigenetic silencing.
  • Exploration of strategies for targeting endogenous regulatory ncRNAs.

Main Results:

  • ncRNAs function as guides for epigenetic silencing complexes, directing them to specific genomic locations.
  • Suppression of ncRNAs regulating protein-coding genes can lead to derepression or activation of target loci.
  • Underlying mechanisms of ncRNA-targeted epigenetic regulation have been elucidated for specific genes.

Conclusions:

  • ncRNA-targeted epigenetic regulation represents a paradigm shift in understanding gene control.
  • Targeting endogenous regulatory ncRNAs enables targeted gene activation.
  • This approach holds significant potential for developing novel treatments for genetic and infectious diseases.
