Area of Science:

  • Genetics
  • Molecular Biology
  • Gerontology

Background:

  • Caenorhabditis elegans possesses four sirtuin (Sir2) paralogs: sir-2.1, sir-2.2, sir-2.3, and sir-2.4.
  • Research on C. elegans sirtuins has predominantly focused on sir-2.1 due to its similarity to yeast SIR2 and human SIRT1.
  • A comprehensive set of research tools for all C. elegans sirtuin family members is currently lacking.

Purpose of the Study:

  • To compile a comprehensive list of available research tools for all C. elegans sirtuin paralogs.
  • To describe established methods for analyzing C. elegans sirtuin function.
  • To provide an overview of phenotypic data for C. elegans sir-2.1.

Main Methods:

  • Compilation of available strains (loss-of-function alleles and transgenics) for all C. elegans sirtuin paralogs.
  • Listing of antibodies and RNA interference (RNAi) constructs relevant to C. elegans sirtuin studies.
  • Description of methods including lifespan analysis, stress-resistance assays, and fat content analysis.

Main Results:

  • A curated list of research tools, including strains, antibodies, and RNAi constructs, for all four C. elegans sirtuin family members is presented.
  • Standardized methods for assessing C. elegans sirtuin function are described.
  • Phenotypic data associated with C. elegans sir-2.1 are summarized.

Conclusions:

  • This compilation provides essential resources for researchers studying C. elegans sirtuins beyond sir-2.1.
  • The described methods and data facilitate a broader investigation into the roles of all C. elegans sirtuin paralogs.
  • This work aims to advance the understanding of sirtuin functions in aging and stress response in C. elegans.
