Human longevity may not be linked to caloric restriction (CR) pathways. Transcriptome analysis suggests human aging differs from CR effects seen in mice, indicating CR or mimicking agents could still extend human lifespan.
Area of Science:
- Genomics
- Evolutionary Biology
- Aging Research
Background:
- Caloric restriction (CR) and related compounds extend lifespan in various species.
- Human maximal lifespan is notably greater than in primates, suggesting unique genetic adaptations.
- The impact of CR or life-extending agents on human aging remains under-investigated.
Purpose of the Study:
- To investigate if human longevity evolved through mechanisms similar to caloric restriction.
- To compare human transcriptome data with CR-induced changes in mice and other primates.
Main Methods:
- Comparative transcriptome analysis between humans, other primates, and mice under CR or ad libitum feeding.
- Identification of conserved gene expression patterns related to aging and CR.
Main Results:
- Human transcriptome profiles do not resemble CR- or resveratrol-treated mice; they align more with ad libitum fed mice.
- CR-induced transcriptome changes in mice are associated with age-related gene expression in primates, particularly in pathways like insulin signaling, cancer, and immunity.
- These findings suggest human longevity evolved independently of CR-mimetic pathways.
Conclusions:
- The evolution of human longevity appears distinct from CR-mediated lifespan extension mechanisms.
- Caloric restriction and CR-mimicking agents represent a potentially promising avenue for extending healthy human lifespan.
