Arecoline upregulates CD155 expression to facilitate immune evasion in oral squamous cell carcinoma.

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
backgroundAreca nut is the fourth most addictive substance worldwide and is a known Group 1 carcinogen. Chronic areca nut chewing has been strongly associated with the development of oral squamous cell carcinoma (OSCC), although the underlying carcinogenic mechanisms remain unclear.
methodsEmploying spatial multiomics technology, we recently mapped the immune microenvironment of areca nut-associated OSCC and identified a marked upregulation of the immune checkpoint molecule CD155 in these tumors. Further quantitative reverse transcription-PCR, western blotting, immunofluorescence, animal experiments, etc, explored and verified the reasons for the upregulation of CD155 caused by arecoline and the results of immune escape in OSCC.
resultsThe investigation revealed that arecoline, a bioactive component of areca nut, induces CD155 expression in OSCC cells. Through interaction with its receptor, TIGIT, CD155 suppresses CD8
conclusionThis study unveils a novel mechanism by which arecoline promotes immune evasion in OSCC and highlights promising immune therapeutic targets and strategies for the treatment of areca nut-associated OSCC.
