Principal component analysis. (a) PCA for the top 95 proteins arranged by ascending p-value from Analysis 1. (b) PCA for the top 515 proteins arranged by ascending p-value from Analysis 2. (c,d) Similar separation between humidity groups is observed by PCA for proteins corresponding to the aggregated functional clusters chaperone response and glutathione-related, respectively. M7–9 and M20–25 indicate the samples from control rabbits exposed to moderate humidity, and L7–9 and L20–25, samples from rabbits exposed to low humidity.
