Ccn2a acts downstream of cx43 to influence joint formation during zebrafish fin regeneration.
Article in Biology open, 2025. 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
This study provides new insights into the molecular pathways dictating skeletal patterning during zebrafish fin regeneration. Connexin43 (Cx43) is known to influence skeletal patterning by inhibiting evx1 expression and thereby regulating the timing of joint formation. Here, we demonstrate that cellular communication network factor 2 (ccn2a) also contributes to this pathway. We find that Ccn2a appears to act downstream of Cx43 and similarly inhibits joint formation by inhibiting evx1 expression. Pharmacological inhibition of β-catenin demonstrates that ccn2a is likely regulated by β-catenin. Additionally, this paper provides evidence that Yap signaling contributes to joint formation through regulating ccn2a. These findings provide novel insights into the role of Ccn2a during skeletal patterning.
