Translation to Extend Human Healthspan While.Ies of transcriptional regulation can allow the identification of upstream regulators (for overview, see de Magalhaes et al). Furthermore, an emerging strategy to study the complex interactions among the various components of biological systems is network biology (Barabasi et al). Provided the complexity of aging, network approaches could possibly be specifically suited to determine crucial regulators of its modulation by the atmosphere. As an illustration, knowing the proteinprotein interaction network of candidate proteins makes it possible for the identification of hubs, proteins with a massive variety of interactions, which usually be extra biologically relevant (Fig.). Together with other biological (e.g kinases and receptors are typically noticed as promising drug targets), medical, and strategic considerations already applied for target choice in drug discovery (for evaluation, see Knowles and Gromo,), the integrated information of agingrelated pathways can help recognize appropriate targets for drug discovery. Moreover, the advent of largescale databases of compounds and drugs, for instance DrugBank (Wishart et al), STITCH (Kuhn et al), along with the Connectivity Map (Lamb et al), paves the strategy to crosslinking longevityCRassociated genes with drug databases to determine candidate molecules for effects on aging. Advances inside the integration of biological (including agingrelated) datasets are paralleled by advances in information integration and network analyses in nutrition and pharmacology (Hopkins,). Biological systems are intrinsically complicated; one example is, CR signaling requires nonlinear pathways, feedback loops, and compensatory mechanisms (Fig.). Multitarget drugs and combinatorial therapies may well for that reason be more profitable than singletarget drugs. A networkbased view of drug discovery is emerging to account for the complexity of human biology (Schadt et al ; Erler and Linding,). Network approaches allows drug developers to take advantage of the significant volumes of "omic" datasets becoming generated and exploit, rather than dismiss, the intricacy of biology, illness, and drug responses to create new therapies (for critique, see Cho et al ; Schadt et al ). Moreover, focusing on drugs that target many proteins, as an alternative to ligands that act on person targets, has benefits in terms of efficacy and toxicity (Hopkins,). Employing combinations of compounds to target numerous pathways and stay away from compensatory mechanisms is another method, one particular already applied in cancer therapies (MericBernstam and GonzalezAngulo,), and in the context of aging is getting explored by corporations for example Genescient.Existing progress in genomics, highthroughput solutions, informatics, and systems biology   must help to develop network approaches that test target combinations resulting within the emerging paradigm of network pharmacology (Keith et al ; Hopkins,). Systematic drugdesign methods directed against a number of targets hold a great deal guarantee in the field of aging (Csermely et al), even though challenges remain in establishing correct computer models of relevant pathways and suitable in vitro and in vivo models for testing. In the same vein, progress in customized medicine and in predicting person responses (e.g employing SNPs) to the environment (including diet, lifestyle, and drugs), might be crucial to maximizing environmental interventions that strengthen well being and counteract aging. Hence, network approaches to each aging and pharmacology are promising future avenues (Simko et al).
