Abstract: 

In spite of enormous efforts and accumulated knowledge, our capabilities for tackling aging and age-related diseases (ARDs), and ultimately to promote longevity are still very modest. What is lacking -- essential data on key players, efficient analytic tools, or both? Here we discuss how the existing data may be integrated and analyzed in the context of miRNA-regulated protein-protein interaction networks. The proposed model highlighted (i) the strong molecular links between aging, longevity, and ARDs; (ii) the possibility and even the preferability of initiating longevity-promoting interventions in adult life; (iii) the potentially important role for miRNA (or siRNA) mediated targeting of some essential longevity-associated genes; (iv) the superiority of multi-target therapy to the common single-target approach in curing ARDs and promoting longevity.

A gradual decrease in the network robustness along with an increased fragility of individual nodes are proposed as being the common mechanisms of both aging and ARDs.
