Area of Science:

  • Biotechnology
  • Molecular Biology
  • Genomics

Background:

  • Aptamers are nucleic acid-based molecules selected through in vitro methods.
  • They exhibit high specificity and affinity for diverse targets, from small molecules to proteins.
  • Aptamers retain their functionality within cellular environments.

Purpose of the Study:

  • To summarize the selection, properties, and applications of aptamers.
  • To highlight aptamers as tools for functional genomics and potential therapeutics.
  • To discuss natural aptameric motifs in gene regulation.

Main Methods:

  • In vitro selection (SELEX) to identify aptamers from random libraries.
  • Characterization of aptamer-target interactions for affinity and specificity.

    • Main Results:

    • Aptamers have been successfully selected against a wide range of targets.
    • Selected aptamers typically exhibit nanomolar affinity and high specificity.
    • RNA aptamers can modulate biological processes, such as viral transcription.

    Conclusions:

    • Aptamers are versatile tools for molecular recognition and functional genomics.
    • They hold promise as therapeutic agents due to their specificity and stability.
    • Natural aptameric motifs play roles in metabolite-regulated gene expression.
