  1. Proteins altered at 3 days post-lesion after strict filtering of the raw data. The significance of the difference between the average iTRAQ ratios for each protein at 3 days post-lesion, compared to the unlesioned control was calculated by analysing peptide ratios (see Additional file 2: Table S2) using a one-tailed, Student’s pairwise t-test. Only significant changes (i.e. those with p values of <0.05) are shown. Column headings refer to the following: protein name = given name in NCBInr database, [NCBI accession number]; Average iTRAQ ratio (3 days post-lesion/unlesioned) = average iTRAQ after data normalisation, +/− standard deviation from mean, [n] = number of peptides used for quantification.
