- W4231946368 abstract "Reverse transcription quantitative PCR (RT-qPCR) is a robust technique for the quantification and comparison of gene expression across multiple tissues. To obtain reliable results, one or more reference genes must be employed to normalize expression measurements among treatments or tissue samples. Candidate reference genes must be validated to ensure that they are stable prior to use in qPCR experiments. The pond snail ( Lymnaea stagnalis ) is a common research organism, particularly in the areas of learning and memory, and is an emerging target for qPCR experimentation. However, no systematic assessment of reference genes has been performed in this animal. Therefore, the aim of our research was to identify stable reference genes to normalize gene expression data from a variety of tissues in L. stagnalis . We evaluated a panel of seven reference genes across six different tissues in L. stagnalis with RT-qPCR. The genes included: elongation factor 1-alpha ( EF1α ), glyceraldehyde-3-phosphate dehydrogenase ( GAPDH ), beta-acti n ( ACTB ), beta-tubulin ( TUBB ), ubiquitin ( UBI ), prenylated rab acceptor protein 1 ( Rapac1 ), and a voltage gated potassium channel ( VGKC ). These genes exhibited a wide range of expression levels among tissues. The stability of each of the genes was consistent when measured by any of the standard stability assessment algorithms: geNorm, NormFinder, BestKeeper and RefFinder. Our data indicate that GAPDH and EF1α are highly stable in the tissues that we examined (central nervous system, tentacles, lips, penis, foot, mantle) as well as in pooled analyses. We do not recommend VGKC for use in RT-qPCR experiments due to its relatively low expression stability. Our results were generally congruent with those obtained from similar studies in other molluscs. Given that a minimum of two reference genes are recommended for data normalization, we suggest GAPDH and EF1α are a strong option for multi-tissue analyses of RT-qPCR data in Lymnaea stagnalis." @default.
