The retardation of aging by caloric restriction: its significance in the transgenic era

Barger, Jamie L, Walford, Roy L, Weindruch, Richard·2003·Experimental Gerontology

Abstract

The retardation of aging and diseases by caloric restriction (CR) is a widely-studied and robust phenomenon. Recent publications describe transgenic and other mutant rodents displaying lifespan extension, and the rapid pace at which these animals are being generated raises the possibility that the importance of the CR paradigm is declining. Here we discuss these models and evaluate the evidence whether or not the aging process is retarded based on longevity, disease patterns and age-associated biological changes. A comparison to rodents on CR is made. Because CR has been investigated for approximately 70 years with increasing intensity, there exists extensive data to document aging retardation. In contrast, for nearly all of the genetically abnormal models of lifespan extension, such data are minimal and often unconvincing; additional studies will be required to validate these strains as suitable models for aging research.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
