Cx43 Facilitates Mesenchymal Transition of Endothelial Cells Induced by Shear Stress.
Article in Journal of vascular research, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesThis study aimed to determine the function of Cx43 in the endothelial-to-mesenchymal transition (EndMT) process of endothelial cells (ECs) and to explore the potential signaling pathways underlying these functions.
methodsECs were extracted from rat aorta. ECs were transfected with Cx43 cDNA and Cx43 siRNA and then exposed to 5 or 12 dyne/cm2. Immunofluorescence staining was used to detect the expression of SM22α, Cx43, and acetylated α-tubulin in ECs. Western blotting was used to detect the protein expression of α-SMA, CD31, Cx43, H1-calponin, Ift88, and p-smad3 in ECs.
resultsThe expression of αSMA, SM22α, and Cx43 was significantly increased, and CD31 was markedly decreased in ECs treated with laminar shear stress at 5 dyn/cm2. The Cx43 cDNA transfection could induce the expression of SM22α or H1-calponin and attenuate CD31 expression in ECs. Also, Cx43 overexpression harms cilia formation in ECs exposed to 5 dyn/cm2, accompanied with the regulated Ift88 and smad signaling.
conclusionsThis study found that laminar shear stress at 5 dyn/cm2 would increase the expression of Cx43 to facilitate the EndMT process of ECs, associated with morphological changes in primary cilia and the decreased expression of Ift88 in ECs.
