Carboxypeptidase E (CPE) inhibits the secretion and activity of Wnt3a.
Article in Oncogene, 2016. 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 Wnt pathway has essential roles in cell proliferation, cell fate determination and tumorigenesis by regulating the expression of a wide range of target genes. As a core signaling cascade, the canonical Wnt pathway is regulated at different levels by numerous proteins. We have previously shown that carboxypeptidase E (CPE) is a novel regulator of the canonical Wnt signaling pathway. Here, we show that CPE and the Wnt3a ligand are co-secreted from cells. We show that although the C'-terminal Lys residue of Wnt3a is critical for its activity and is important for the effect of CPE on the Wnt pathway, CPE does not execute its effect by removing this Wnt3a residue. Interestingly, CPE through its N'-terminal sequence, forms aggregates with Wnt3a and possible endoplasmic reticulum (ER) stress leading to its loss of function. Together, our current results provide a mechanistic insight into the way CPE regulates the canonical Wnt signaling pathway.
