Fact check
AI analysis“The research team used three molecular “aging clocks” to estimate the biological ages of tissues and whole organisms.”
Reasoning
The primary research article explicitly states that three molecular aging clocks—epigenetic (DNA‑methylation), transcriptomic (RNA expression), and proteomic (plasma protein levels)—were applied to estimate biological age of donor tissues and whole recipient organisms. Two independent news reports echo this description, providing consistent supporting evidence with no contradictory information.
On confidence: Multiple independent sources, including the primary peer‑reviewed article, directly confirm the statement.
Important context
The three clocks used are DNA‑methylation, transcriptomic, and proteomic clocks, employed to assess biological age across both specific tissues (donor organs) and the entire organism (recipient mice).

We applied three independent molecular aging clocks—an epigenetic clock based on DNA methylation, a transcriptomic clock based on RNA expression, and a proteomic clock based on plasma protein levels—to estimate the biological age of donor…

The investigators used three molecular “aging clocks”—DNA‑methylation, transcriptomic and proteomic clocks—to calculate the biological ages of both donor organs and the whole recipient mice.

In the new paper, the research team employed three molecular aging clocks (epigenetic, transcriptomic, and proteomic) to assess biological age across tissues and whole organisms.
Limitations
Evidence is limited to the cited study and its reporting; no additional studies are referenced that might challenge the methodology, but none are needed for verifying the factual claim as presented.
