RNA interference (RNAi) utilizes double-stranded RNA (dsRNA) or small interfering RNA (siRNA) for gene silencing. This review assesses RNAi

Area of Science:

  • Molecular Biology
  • Genetics
  • Biotechnology

Background:

  • RNA interference (RNAi) is a natural biological process in eukaryotic cells where small interfering RNAs (siRNAs) and microRNAs induce gene silencing.
  • The discovery of RNAi's potential as a reverse genetic tool has revolutionized gene function studies and therapeutic development.
  • RNAi technology has expanded into mammalian systems, offering precise control over gene expression.

Purpose of the Study:

  • To evaluate RNA interference (RNAi) as a potent tool for developing gene-silencing therapeutics.
  • To assess the potential of double-stranded RNA (dsRNA) and small interfering RNA (siRNA) in therapeutic applications.
  • To review the application of RNAi in elucidating gene function in mammalian cells.

Main Methods:

  • Systematic review of current research reports on RNA interference (RNAi) phenomena and applications.
  • Inclusion of published papers detailing RNAi discovery, mechanisms, and gene function studies in mammalian cells.
  • Analysis of studies employing synthetic siRNAs and siRNA-expressing vectors for gene silencing.

    • Main Results:

    • RNAi, particularly using siRNAs, has proven effective in elucidating gene function in mammalian systems.
    • The selective, long-term, and systemic gene-modulating effects of RNAi have been observed.
    • Concerns regarding the effectiveness and therapeutic potential of RNAi in mammals have been raised and addressed in recent reports.

    Conclusions:

    • RNAi, delivered as siRNAs or via DNA vectors, significantly accelerates gene function studies in mammals.
    • RNAi presents a promising strategy for developing highly gene-specific therapeutic methods.
    • The potential for RNAi to treat human diseases is a significant future prospect.
