Analysis of L1 Cell Adhesion Molecule and Fucosyltransferase 8 Expression in Cells After Stretch and Human EACSCC Tissue.

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
Background: External auditory canal (EAC) squamous cell carcinoma (SCC) is classified as a rare cancer and has a poor prognosis at advanced stages. Mechanical stress has been implicated in external auditory canal squamous cell carcinoma (EACSCC), but the molecular mechanism has not been elucidated. Mechanotransduction is well-known for Yes-associated protein (YAP) signaling. When YAP is translocated to the nucleus, the L1 cell adhesion molecule (L1CAM) is activated as an effector of mechanotransduction. Core fucosylation of L1CAM by Fucosyltransferase 8 (FUT8) has been implicated in the degree of tumor malignancy, modulating cleavage of the extracellular domain of L1CAM. Methods: In this study, an expression analysis of YAP, L1CAM, and FUT8 was performed by stretch assay in vitro. Immunohistochemistry was also performed in human EACSCC and normal skin specimens. Results: The labeling index of FUT8-positive cells exhibited YAP nuclear translocation under stretch stress was significantly higher in a human SCC cell line (HSC1) than in a human keratinocyte cell line. Stretch stress significantly increased the expression levels of full-length L1CAM in HSC1 cells. Moreover, colocalization of FUT8 and L1CAM was demonstrated immunohistochemically in advanced human EACSCC tissues. Conclusion: These results suggested that L1CAM expression is increased under mechanotransduction and may possibly avoid L1CAM cleavage by FUT8 modulation.
