Differential proteome analysis of hagfish dental and somatic skeletal muscles.
Article in Marine biotechnology (New York, N.Y.). 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
Hagfish, the plesiomorphic sister group of all vertebrates, are deep-sea scavengers. The large musculus (m.) longitudinalis linguae (dental muscle) is a specialized element of the feeding apparatus that facilitates the efficient ingestion of food. In this article, we compare the protein expression in hagfish dental and somatic (the m. parietalis) skeletal muscles via two-dimensional gel electrophoresis and mass spectrometry in order to characterize the former muscle. Of the 500 proteins screened, 24 were identified with significant differential expression between these muscles. The proteins that were overexpressed in the dental muscle compared to the somatic muscle were troponin C (TnC), glycogen phosphorylase, beta-enolase, fructose-bisphosphate aldolase A (aldolase A), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). In contrast, myosin light chain 1 (MLC 1) and creatine kinase (CK) were over-expressed in the somatic muscle relative to the dental muscle. These results suggest that these two muscles have different energy sources and contractile properties and provide an initial representative map for comparative studies of muscle-protein expression in low craniates.
