Before revision:  Our model predicts that the rate of aging, defined by the Gompertz coefficient, is  proportional to the average number of active interactions per gene in the network and that stochastic heterogeneity of gene interactions is an important factor in shaping the dynamics of the aging process.
After revision:  Our model predicts that the rate of aging, defined by the Gompertz coefficient, is approximately proportional to the average number of active interactions per gene in the network and that stochastic heterogeneity of gene interactions is an important factor in shaping the dynamics of the aging process.
