Renalase Peptide (RP220) Activates MAPK Signaling Pathways in Primary Mouse Skeletal Muscle Cells.
Article in microPublication biology, 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
Renalase is a secreted protein that was initially discovered in the kidney and that is also expressed in skeletal muscle. Moreover, renalase peptide RP220 activates MAPK signaling in the kidneys. This study investigated the effects of the RP220 on skeletal muscle using primary cultured cells. Notably, RP220 treatment did not alter the myogenic differentiation phenotype; however, intracellular signaling analyses revealed significant phosphorylation of p38 and ERK, which are MAPK family members. These results indicate that renalase affects MAPK signaling, but its physiological or developmental effects on skeletal muscle are not yet known.
