Researchers led by the University of Michigan found that ergothioneine, a compound obtained from fungi such as mushrooms, rose in the brains and blood of mice across five lifespan-extending treatments. The study examined rapamycin, acarbose, canagliflozin, 17α-estradiol, and caloric restriction.

Why it matters

Aging-related diseases such as dementia, vision loss, cancer, and osteoporosis become more prevalent in later years, making markers that track anti-aging effects of interest to researchers. The study found no direct evidence of cause and effect for ergothioneine, so its role remains unconfirmed.

The AI analysis correctly identified the fifth treatment's mice in 33 of 35 tests, drawn from five lifespan-extending treatments studied in male mice. Whether ergothioneine drives these effects or merely accompanies them has not been established.

The players

University of Michigan

A public research university in Ann Arbor, Michigan, whose research team led the study identifying ergothioneine as a shared marker across lifespan-extending treatments.

The details

Researchers rotated through the five treatments in groups of four and used an AI program to find consistent patterns in mouse biology. Ergothioneine was the only molecule ranking as a top marker in more than two tissue types, and scientists are now comparing mice given anti-aging drugs with mice given drugs known not to alter lifespan.

Research Context

The study builds on existing work with rapamycin, one of five treatments examined, to look for a common biological signature across different anti-aging approaches. Its finding that ergothioneine rises under each treatment points toward biomarkers that could help rank anti-aging drugs more quickly.

The study is in mice and does not show that ergothioneine affects human aging or health. Readers should not change their diet or supplements based on these findings until human research is available.

The takeaway

Ergothioneine appears consistently in mice receiving different anti-aging treatments, but its role has not been proven. Further work comparing anti-aging drugs with non-lifespan-extending drugs will determine whether this marker is useful.
