beta-Actin is a useful internal control for tissue-specific gene expression studies using quantitative real-time PCR in the half-smooth tongue sole Cynoglossus semilaevis challenged with LPS or Vibrio anguillarum.
beta-Actin has been frequently used as an internal control (gene) or as a housekeeping gene to normalize the expression of the target gene(s) or mRNA levels between different samples. However, the beta-actin expression has been shown to be influenced by the sample type and experimental conditions. If beta-actin could be used as a reference gene for the half-smooth tongue sole Cynoglossus semilaevis remains ill-defined. Here we evaluate the tissue-specific beta-actin gene expression pattern in C. semilaevis when challenged with antigenic agents namely, lipopolysaccharide (LPS) or Vibrio anguillarum employing absolute quantitative real-time PCR. The real-time PCR was performed based on the standard curve generated from recombinant plasmids. No significant differences in beta-actin expression were found between treated and untreated tissue samples. We thus conclude that beta-actin could be used as a reliable internal reference gene for real-time PCR based quantitation of gene expression studies in various tissue samples of C. semilaevis challenged with LPS or pathogenic bacteria.
