Cross species activity of TERT human telomerase component.
Article in Aging, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Telomerase is a cellular enzyme that adds telomeric DNA sequences to the ends of chromosomes, aiding in preserving genome stability. The enzyme is formed by a protein with reverse transcriptase activity (TERT) and an RNA molecule that provides the sequence used as a template (TERC). These two components must interact precisely for telomerase to function, and their compatibility varies across species. Understanding whether the human protein component can function with the RNA molecules of other species is important for the development of therapies that activate telomerase, particularly those aimed at treating disorders associated with short telomeres. Here, we investigate the ability of the human TERT to interact with the telomerase RNA from several mammalian species commonly used in preclinical research, including monkey, pig, dog, rabbit, rat, and mouse. We introduced the human TERT into primary lung fibroblasts from each species and assessed its capacity to generate telomeric repeats in cell extracts. We also analyzed telomere length during extended cell culture to determine whether telomeres lengthened over time. Human TERT formed an active complex with the telomerase RNA from monkey, pig, rabbit, and rat
