The telomerase activator TA‐65 elongates short telomeres and increases health span of adult/old mice without increasing cancer incidence
Open accessAbstract
Summary: Here, we show that a small‐molecule activator of telomerase (TA‐65) purified from the root of Astragalus membranaceus is capable of increasing average telomere length and decreasing the percentage of critically short telomeres and of DNA damage in haploinsufficient mouse embryonic fibroblasts (MEFs) that harbor critically short telomeres and a single copy of the telomerase RNA Terc gene (G3 Terc+/− MEFs). Importantly, TA‐65 does not cause telomere elongation or rescue DNA damage in similarly treated telomerase‐deficient G3 Terc−/− littermate MEFs. These results indicate that TA‐65 treatment results in telomerase‐dependent elongation of short telomeres and rescue of associated DNA damage, thus demonstrating that TA‐65 mechanism of action is through the telomerase pathway. In addition, we demonstrate that TA‐65 is capable of increasing mouse telomerase reverse transcriptase levels in some mouse tissues and elongating critically short telomeres when supplemented as part of a standard diet in mice. Finally, TA‐65 dietary supplementation in female mice leads to an improvement of certain health‐span indicators including glucose tolerance, osteoporosis and skin fitness, without significantly increasing global cancer incidence.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
