What the research examined
A mouse study examined late-life semaglutide and reported lifespan and functional findings in female mice. Separately, a post hoc analysis from a trial in people with HIV-associated lipohypertrophy examined DNA-methylation measures described as epigenetic aging clocks.
How to interpret the findings
A molecular clock is a surrogate measurement, not a count of additional years lived. The human analysis was exploratory, modest in size, and population-specific. Neither it nor the female-mouse experiment establishes extended human lifespan.
