Anti-aging effects of guanosine in glial cells.
Article in Purinergic signalling, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 papers.
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
Guanosine, a guanine-based purine, has been shown to exert beneficial roles in in vitro and in vivo injury models of neural cells. Guanosine is released from astrocytes and modulates important astroglial functions, including glutamatergic metabolism, antioxidant, and anti-inflammatory activities. Astrocytes are crucial for regulating the neurotransmitter system and synaptic information processes, ionic homeostasis, energy metabolism, antioxidant defenses, and the inflammatory response. Aging is a natural process that induces numerous changes in the astrocyte functionality. Thus, the search for molecules able to reduce the glial dysfunction associated with aging may represent an approach for avoiding the onset of age-related neurological diseases. Hence, the aim of this study was to evaluate the anti-aging effects of guanosine, using primary astrocyte cultures from newborn, adult, and aged Wistar rats. Concomitantly, we evaluated the role of heme oxygenase 1 (HO-1) in guanosine-mediated glioprotection. We observed age-dependent changes in glutamate uptake, glutamine synthetase (GS) activity, the glutathione (GSH) system, pro-inflammatory cytokine (tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β)) release, and the transcriptional activity of nuclear factor kB (NFkB), which were prevented by guanosine in an HO-1-dependent manner. Our findings suggest guanosine to be a promising therapeutic agent able to provide glioprotection during the aging process. Thus, this study contributes to the understanding of the cellular and molecular mechanisms of guanosine in the aging process.
