α7-Nicotinic Acetylcholine Receptor Promotes Cholangiocarcinoma Progression and Epithelial-Mesenchymal Transition Process.
Article in Digestive diseases and sciences, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers, 1 of them a synthesis that pooled it.
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
backgroundCholangiocarcinoma is one of the most deadly malignant tumors characterized by a tendency of local invasiveness and metastasis at the early phase, high recurrence rate, and difficulty in treatment. Alpha7-nicotinic acetylcholine receptor (α7-nAChR) is highly expressed in a variety of tumors, including cholangiocarcinoma, and may promote tumor progression, but the mechanisms are largely unknown.
aimsOur study is the first to expound upon the role that α7-nAChR plays in cholangiocarcinoma.
methodsWe assessed 50 human cholangiocarcinoma tissue samples and 20 normal biliary samples using immunohistochemical staining to find the correlation between α7-nAChR expression and clinicopathological characteristics. We used human cholangiocarcinoma cell lines QBC939 and RBE and α7-nAChR gene knockdown RBE cell lines generated by shRNA lentivirus transfection to investigate the biological functions of α7-nAChR in proliferation, apoptosis, migration, and invasiveness in vitro. Further, western blotting was used to detect apoptosis and epithelial-mesenchymal transition (EMT)-related signaling proteins. Cholangiocarcinoma xenografts in nude mice were used for tumorigenicity assays in vivo.
resultsThe expression of α7-nAChR was high in cholangiocarcinoma tissues and was closely related to a shorter survival time in patients. α7-nAChR knockdown decreased cell proliferation ability, increased early apoptosis, and weakened cell migration and invasion. Apoptosis-related proteins and components of the EMT process were altered after α7-nAChR knockdown. Moreover, nude mice xenograft experiments confirmed that α7-nAChR could promote cholangiocarcinoma in vitro.
conclusionsOverexpression of α7-nAChR induces cholangiocarcinoma progression by blocking apoptosis and promoting the EMT process. As an effective molecular biomarker and prognostic factor, α7-nAChR is a promising therapeutic target in cholangiocarcinoma.
