CLCa mediates a novel cross-talk between Wnt secretion and actin organization.
Article in Life science alliance, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Mammalian clathrin light chains (CLCa, CLCb) are critical players in clathrin-mediated endocytosis. However, their physiological role in contributing to specific cellular processes and early development remains elusive. To elucidate their individual functions, we generated CLC knockout mESCs. Loss of CLCa resulted in down-regulation of Wnt pathway genes along with altered secretion of Wnt3a because of impaired trafficking of its secretion mediator, WLS. Reduced Wnt signaling led to lower levels of Hip1R causing a reorganization of the actin cytoskeleton. CLCa knockout cells displayed actin patches enriched for Arp3 and cortactin, with activation of the Wnt pathway resulting in disassembly of these patches. Furthermore, we uncovered a bidirectional cross-talk between Wnt signaling and actin organization, with actin disruption resulting in lower Wnt signaling. Our data reveal a previously undiscovered role of CLCa in mediating molecular communication between actin organization and Wnt signaling.
