Abstract

Telomeres, the protective caps of chromosomes, shorten with age, as telomerase, the enzyme responsible for the compensation of telomere erosion, is inactive in the majority of cells. Telomere shortening and subsequent cell senescence lead to tissue aging and age‑related diseases. Neurodegenerative disorders, characterized by the progressive loss of neurons among other hallmarks of aged tissue, and poor cognitive function, have been associated with a short telomere length. Thus, telomerase activity has emerged as a therapeutic target, with novel agents being under investigation. The present study aimed to examine the effects of a novel natural telomerase activator, ‘Reverse™’, containing Centella asiatica extract, vitamin C, zinc and vitamin D3 on the brains of 18‑month‑old rats. The administration of the ‘Reverse™’ supplement for 3 months restored telomerase reverse transcriptase (TERT) expression in the brains of rats, as revealed by ELISA and immunohistochemistry. In addition, the findings from PCR‑ELISA demonstrated an enhanced telomerase activity in the cerebellum and cortex cells in the brains of rats treated with the ‘Reverse™’ supplement. The histopathological findings confirmed a structural reversibility effect close to the differentiation observed in the young control group of rats treated with two capsules/kg body weight of the ‘Reverse™’ supplement. On the whole, the findings of the present study provide a strong indication that an increased telomerase activity and TERT expression may be achieved not only in the postnatal or embryonic period, but also in the brains of middle‑aged rats through nutraceutical supplementation. The use of the ‘Reverse™’ supplement may thus contribute to the potential alleviation of a number of central nervous system diseases.

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.
