Suitable reference genes are expected to exhibit constant expression levels. However no single gene is constitutively expressed in all cell types and under all experimental conditions. It has become clear that expression stability of the intended reference gene has to be examined before each experiment. For expression studies using quantitative real-time PCR (qPCR) at least two reference genes have to be applied. So far expression studies in the European seabass (Dicentrarchus labrax) as well as in the Gilthead seabream (Sparus aurata) have been performed with only one reference gene (S18, Ef-1 alpha or Gapdh). Though significant variations showed up in other teleost species such as the Atlantic halibut and the zebrafish affirming the need for proper normalization strategies, the present study aims at identifying suitable reference genes among nine candidates [glyceraldehyde-phosphate-dehydrogenase (Gapdh), β-actin (two regions of β-actin), 40S ribosomal protein S30 (Fau), ribosomal protein L13 a (L13a), β2-tubulin (Tubb2) and tyrosine 3 monooxygenase/tryptophan 5-monooxygenase activation protein (Tyr)] for expression analysis of 8 developmental stages and a tissue panel (spleen, liver, kidney and brain) with samples infected with Nodavirus and Vibrio anguillarum in D. labrax. Besides the analysis of raw Ct-values, the gene expression stability was determined using two different software applications BestKeeper and NormFinder. According to both algorithms the best two reference genes for an appropriate normalization approach during D. labrax development are Ef-1 alpha and L13a whereas in the tissue panel Fau and L13a are recommended for qPCR normalization. | Descripción: | 8 pages, 6 figures, 5 tables.-- PMID: 19398033 [PubMed].-- Printed version published Aug 2009.
