Definition
Animal versus human studies in epigenetics differ in methodological control, generalizability, and clinical translation. The two literatures are often blurred in popular discussion.
Why it matters
Findings robust in mice can be nowhere near translation to humans. Confusing the two produces overclaim.
The Science
Rodent studies allow controlled breeding, tissue sampling, and mechanistic dissection. Human studies typically rely on peripheral tissue (blood), correlational designs, and small effect sizes. Extrapolation requires care.
The NSI Perspective
NSI insists on this distinction as a matter of intellectual honesty.
Clinical Implications
When "epigenetics shows..." is followed by mouse evidence, translation is not automatic.
Practical Application
If the exciting finding is from mice, treat it as promising — not personal.
