SRSF1 gene: older cells with a younger profile in mice
A study in mice and human skin cells indicates that the SRSF1 gene made old cells look younger and that senescence fell in the human cells. The findings are preliminary.

What the research shows
According to the publication, a study in mice and human skin cells investigated the SRSF1 gene. The authors reported that SRSF1 made old cells show a younger profile. In old mice, median lifespan was 14% longer. In the human skin cells, senescence, a state in which cells stop dividing, decreased.
It is worth noting that the findings are preliminary. They were observed in animals and cells, not in people, and a result in mice does not guarantee the same effect in humans. The study helps explain a mechanism of aging, but much more research is needed before any clinical application.
What it means
The finding suggests that SRSF1 may be a point of interest for aging research. It is not yet known whether the same happens in people, or what the risks and benefits of acting on this pathway would be.
How to read it with care
Read this result with caution: a study in animals and cells does not replace a consultation. Anyone considering a change in diet, supplements or treatment should talk to a doctor or another qualified health professional.
