IF1 protein and aging: preprint in mice and across species
A preprint not yet peer reviewed reports that the IF1 protein inhibits ATP hydrolysis and that higher IF1 correlates with greater maximum lifespan across species.

What the research shows
The preprint, not yet peer reviewed, describes the IF1 protein inhibiting ATP hydrolysis, a reaction linked to how cells use energy. The authors report that, across species, higher IF1 levels correlate with greater maximum lifespan. In mice, more IF1 reduced a biomarker of aging.
Findings like this help explain possible energy-related mechanisms behind aging, but a correlation across species does not prove the protein causes a longer life. Because the study has not yet been peer reviewed, its results should be treated as preliminary until other researchers examine and confirm them.
What it means
The finding suggests IF1 may be related to the pace of aging through cellular energy metabolism. It is still unclear whether the same effect occurs in humans, or how much this mechanism really matters for longevity.
