  1. Relative expression levels of R. flavipes gene transcripts (average ± standard error), identified using cDNA macroarrays and quantified by quantitative PCR. Data shown in bold-face type represent the highest relative expression for a given gene (LSD t-test; P ≤ 0.05). Relative expression calculated using the method described by Pfaffl et al. [44] (n = 3). See Additional data file 2 for raw data. †All results are normalized to the control gene β-actin. Primers designed from mouse and rat sequences (Accession nos. X03672 and V01207), as described by Giulietti et al. [43]. ‡Clone numbers correspond to the order shown in Table 1 (numbers 16 and lower have significant identity scores). See Additional data file 1 and 9, respectively, for sequence and primer details.
