Genetic Dietary Restriction Gene Manipulations Database

Genetic Dietary Restriction (GenDR) Gene Manipulations Database is an informational resource on genes related to dietary restriction (DR), the most powerful non-genetic intervention shown to extend lifespan in a wide range of model organisms. Specifically, this dataset includes a manually curated list of DR-essential genes (“Gene manipulations”).

DR-essential genes are genes that when genetically manipulated (e.g. by loss-of-functions such as mutation, transposition, or knockdown, or by gain-of-function like overexpression of additional transgenes) interfere with the ability of DR to extend the lifespan. In the ideal case, a genetic alteration of a DR-essential gene does not change the lifespan on ad libitum (AL) but totally cancels out lifespan-extension by a restricted diet.

In such cases, their selection criteria follow the same logic behind GenAge but focus specifically on those genes which are necessary for the modulation of the aging process by diet (which are by definition not necessary also aging genes).

A focus on genes from gene manipulation experiments means that the selection procedure for including genes related to DR will be more objective and unbiased, just like for GenAge. Nonetheless, as there are multiple different forms of DR regimens, most of which can be applied at several different levels of severity, genes were included if there is evidence that they interfere with at least one kind of DR regimen or strength of restriction. This includes by definition a shift in the response to the food concentration at which lifespan is extended (e.g. chico).

Each record in GenDR on a DR-essential gene contains comments (i.e. observations) about literature-based evidence and the reason(s) for inferring an association with DR. References are also cited. In the case of conflicting reports for a given gene, the policy is to still include this gene in GenDR but mention all the conflicting studies.

Specific for yeast, genes which are DR-essential in either a replicative or a chronological lifespan assay were included. Both the specific DR regimen and the aging model in which a gene was found to be essential for DR-lifespan extension is annotated in GenDR. The intention for using a broad definition of DR-essential genes, rather than a more specific one, is that this will make it possible to focus on mechanisms universal to DR and therefore more likely relevant to human aging.

Understanding the genetic basis of DR is of great importance not only to the biology of aging but to understand how diet can influence aging, longevity, health and age-related diseases. Pharmaceutical interventions that target DR-associated genes are also an emerging area with huge potential.
