Figure 7. Impact of sexual dimorphism on the serum proteome profiles of wild type and WrnΔhel/Δhel mice at four and ten months of age. (A) Principal component analysis (PCA) graph of all wild type and WrnΔhel/Δhel mice at four and ten months of age. (B) Heatmap depicting the Z-score value of log base 2 of serum protein (rows) between individual (columns) wild type and WrnΔhel/Δhel that significantly separated females and males. (C) Venn diagram presenting the number of quantified proteins that were unchanged or altered between the different groups of females. (D) Venn diagram presenting the number of quantified proteins that were unchanged or altered between the different groups of males.
