Expression profiles of the 19 identified differential proteins. (A) Differential expression profiles of the 19 identified differential protein spots (arrowheads) from pH 3–10 in 2-DE gel templates. (B) The excised protein spots from the regions of interest in A. Arrowheads represent protein spots that showed significantly different changes. Spot numbers are consistent with those shown in Table1. (C). Histograms of the 19 differential proteins in the three groups. Data are presented as mean ± SD (n = 10 per group).
