USO1 expression is dysregulated in non-small cell lung cancer.
Article in Translational lung cancer research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background: USO1 vesicle transport factor (USO1) is a vesicular transport factor crucial for endoplasmic reticulum (ER) to Golgi transport and is required for transcytotic fusion and subsequent binding of the vesicles to the target membrane. USO1 has been studied in multiple cancers revealing high levels of expression and exerting its oncogenic role by increasing cell proliferation and evasion of apoptosis. Furthermore, multiple studies have implicated dysregulation of the Erk signalling pathway in the involvement of USO1 in multiple cancers. Overall survival (OS) in non-small cell lung cancer (NSCLC) remains low despite recent advances in treatments which are mainly due to the late stage of diagnosis and a significant cohort of patients lacking an available targeted therapy. The aim of this study was to investigate USO1 expression in NSCLC. Methods: An in-house NSCLC tissue microarray (TMA) comprising (n=204 patients) was stained for USO1. Scoring intensity (H score) was used to interrogate for correlations between USO1 expression and established prognostic factors, and OS. Further evaluation of the expression of USO1 in NSCLC was done using multiple online datasets including Lung Cancer Explorer (LCE), UALCAN, GEPIA, KM plotter, TIMER2 and MuTarget. Results: USO1, when highly expressed in lung adenocarcinomas (LUADs) leads to a significantly increased OS (P=0.028). There was no significant correlation between age, smoking status, lymph node status, tumour subgroup and stage. USO1 was significantly higher in patients with tumour size <5 cm compared to those ≥5 cm (P=0.016). Overexpression in LUAD occurred at an early stage being significantly upregulated in Stage 1 and N0 tumours. USO1's first neighbours, also involved in ER-Golgi transport have altered expression in LUAD and significantly impact overall survival. Overexpression occurred independently of commonly mutated genes in NSCLC and had no correlation with changes in the TME. Conclusions: This study highlights the importance of USO1 and ER-Golgi vesicular transport system in LUAD. USO1 overexpression occurs as an early event in LUAD and independently of commonly mutated genes in NSCLC and therefore may represent an attractive diagnostic biomarker as well as a potential target for treatment.
