FIG. 4.
Modified schematic representation of findings, after Hou et al. (43). The authors sought transcriptomic changes due to diet restriction in Caenorhabditis elegans that were similar to transcriptomic changes arising from genetic perturbations. In this way, they were able to identify a “regulator-target-cluster” network of interacting genes associated with the lifespan-extending effects of diet restriction. DR, diet restricted.
