Comparative Proteome Analysis Indicates The Divergence between The Head and Tail Regeneration in Planarian.
Article in Cell journal, 2021. 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
objectiveEven a small fragment from the body of planarian can regenerate an entire animal, implying that the different fragments from this flatworm eventually reach the same solution. In this study, our aim was to reveal the differences and similarities in mechanisms between different regenerating fragments from this worm. MATERIALS AND
methodsIn this experimental study, we profiled the dynamic proteome of regenerating head and tail to reveal the differences and similarities between different regenerating fragments using 2-DE combined with MALDITOF/ TOF MS.
resultsProteomic profiles of head and tail regeneration identified a total of 516 differential expressed proteins (DEPs) and showed a great difference in quantity and fold changes of proteome profiles between the two scenarios. Briefly, out of the 516 DEPs, 314 were identified to be specific for anterior regeneration, while 165 were specific for posterior regeneration. Bioinformatics analysis showed a wide discrepancy in biological activities between two regenerative processes; especially, differentiation and development and signal transduction in head regeneration were much more complex than that in tail regeneration. Protein functional analysis combined with protein-protein interaction (PPI) analysis showed a significant contribution of both Wnt and BMP signaling pathways to head regeneration not but tail regeneration. Additionally, several novel proteins showed completely opposite expression between head and tail regeneration.
