Weekly doses of a compound extended lifespan in aged mice
Median lifespan rose about 14% and maximum lifespan about 12% in aged mice given the compound weekly.
Limit: The abstract does not report adverse effects
Edited by Boris Djordjevic · AgingResearch.News
In an animal experiment, aged mice received weekly doses of a compound designed to make cells break down HIF-1α, a protein involved in responses to low oxygen. The compound lowered the protein’s levels across multiple organs, reduced a range of age-related abnormalities and extended lifespan.
The researchers developed the compound to copy a protective process they identified in intervertebral discs, the cushions between spinal bones. Comparisons of molecular signs of aging across tissues indicated that these discs aged slowly. The researchers linked this to persistently low oxygen and specialized disc cells’ ability to break down HIF-1α through autophagy, a process that breaks down and recycles cell material. This process limited cellular stress.
Why it matters
Slowly aging spinal discs offer a way to investigate why tissues age at different rates and whether their protective processes can be used elsewhere.
Caveats
These were animal results, not evidence of longer life in people. The abstract does not report the number of mice, dose, treatment duration or adverse effects.
