Molecular basis of radiation resistance in tardigrades and the medical implications.
Review in World journal of radiology, 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
Tardigrades exhibit remarkable resistance to ionizing and ultraviolet radiation, tolerating exposures far beyond the lethal limits for most organisms. Among the tardigrade-derived molecules implicated in this resilience, damage suppressor (Dsup) is the most well-characterized and demonstrates clear radioprotective activity. This mini-review summarizes the molecular mechanisms underlying tardigrade radiation resistance and discusses their potential medical applications. Dsup associates with chromatin, reducing hydroxyl-radical-induced DNA strand breaks and limiting ultraviolet-mediated pyrimidine dimer formation. Human cells expressing Dsup exhibit decreased DNA damage by approximately 40% and enhanced survival following irradiation, indicating that essential protective mechanisms of tardigrades can be functional in mammalian systems. These findings support the exploration of Dsup-based strategies to mitigate radiation-induced cellular injury, improve preservation of biological materials, and enhance resilience in high-radiation environments such as radiotherapy or space missions. Further mechanistic studies of Dsup, DNA repair pathways, and antioxidative systems, along with
