Fig. 3From: Proteomic analysis reveals that aging rabbit vocal folds are more vulnerable to changes caused by systemic dehydrationPrincipal component analysis (PCA) based on the proteomic data showing the separation of groups by a age, b hydration status, c interaction of both factors, and d all significant proteins from each effect combined. PCA plots are based on the top 500 proteins for age and hydration status main factors, top 250 proteins for interaction, and all significant proteins (p ≤ 0.05) organized by ascending p-value. OC: older-control; OD: older-dehydrated; YC: young-control; YD: young-dehydratedBack to article page
