Figure 7From: Protein protein interactions, evolutionary rate, abundance and ageAge and Connectivity when controlling for Expression. To control for expression, a bin of proteins is selected from the Age and Expression graph. The proteins in this bin are reanalysed to check if the correlation between age and connectivity still remains. This stratification demonstrates that expression levels have very little effect on the relationship we observe between age and interactions ρ: 0.91762).Back to article page
