p38 MAPK regulates PKAα and CUB-serine protease in Amphibalanus amphitrite cyprids.
Article in Scientific reports, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The MKK3-p38 MAPK pathway has been reported to mediate larval settlement in Amphibalanus (=Balanus) amphitrite. To clarify the underlying molecular mechanism, we applied label-free proteomics to analyze changes in the proteome of cyprids treated with a p38 MAPK inhibitor. The results showed that the expression levels of 80 proteins were significantly modified (p < 0.05). These differentially expressed proteins were assigned to 15 functional groups according to the KOG database and 9 pathways were significantly enriched. Further analysis revealed that p38 MAPK might regulate the energy supply and metamorphosis. Two potential regulatory proteins, CUB-serine protease and PKAα, were both down-regulated in expression. CUB-serine protease localized to postaxial seta 2 and 3, as well as the 4 subterminal sensilla in the antennule. Importantly, it was co-localized with the neuron transmitter serotonin in the sections, suggesting that the CUB-serine protease was present in the neural system. PKAα was highly expressed during the cyprid and juvenile stages, and it was co-localized with phospho-p38 MAPK (pp38 MAPK) to the cement gland, suggesting that PKAα might have some functions in cement glands. Overall, p38 MAPK might regulate multiple functions in A. amphitrite cyprids, including the energy supply, metamorphosis, neural system and cement glands.
