Time-dependent unloading effects on muscle and bone and involvement of FNDC5/irisin axis.
Article in NPJ microgravity, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled it.
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
The identification of biomarkers and countermeasures to prevent the adverse effects on the musculoskeletal system caused by the absence of mechanical loading is the main goal of space biomedical research studies. In this study, we analyzed over 4 weeks of unloading, the modulation in the expression of key proteins in Vastus lateralis, Gastrocnemius and cortical bone in parallel with the modulation of irisin serum levels and its precursor FNDC5 in skeletal muscle of hind limb unloaded (HU) mice. Here we report that Atrogin-1 was up-regulated as early as 1- and 2-week of unloading, whereas Murf-1 at 2- and 3-weeks, along with a marked modulation in the expression of myosin heavy chain isoforms during unloading. Since HU mice showed reduced irisin serum levels at 4-weeks, as well as FNDC5 decrease at 3- and 4-weeks, we treated HU mice with recombinant irisin for 4 weeks, showing that unloading-dependent decline of myosin heavy chain isoforms, MyHCIIα and MyHCIIx, and the anti-apoptotic factor Bcl2, were prevented. In parallel, irisin treatment inhibited the increase of the senescence marker p53, and the pro-apoptotic factor Bax. Overall, these results suggest that the myokine irisin could be a possible therapy to counteract the musculoskeletal impairment caused by unloading.
