RNA interference (RNAi) is a powerful gene silencing method. Small interfering RNAs (siRNAs) enable targeted gene function studies in mammalian cells, aiding research in oncogenesis and infectious disease.

Area of Science:

  • Molecular Biology
  • Genetics
  • Biotechnology

Background:

  • The Human Genome Project necessitates efficient gene function study methods.
  • RNA interference (RNAi) is a conserved gene silencing mechanism.
  • Small interfering RNAs (siRNAs) are key mediators of RNAi.

Purpose of the Study:

  • To review the mechanism of RNA interference.
  • To outline current medical applications of RNAi.
  • To highlight RNAi as a tool for studying gene function.

Main Methods:

  • RNA interference (RNAi) mechanism.
  • Processing of double-stranded RNA (dsRNA) into siRNAs by Dicer.
  • Formation of RNA-induced silencing complex (RISC) and target transcript cleavage.
