1 · What the graph read from 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.

2 · The registry

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

backgroundThe deubiquitinase OTUB1 plays critical oncogenic roles and facilitates tumor progression in cancer. However, less is known regarding the aberrant expression, clinical significance and biological functions of the non-coding RNA OTUB1-isoform 2. We aimed to evaluate the OTUB1-isoform 2 levels in gastric cancer and their possible correlation with clinicopathologic features and patient survival to reveal its biological effects in gastric cancer progression.

methodsTotal RNA extraction was performed on 156 gastric cancer case samples, and RT-qPCR was conducted. Chi-square test analysis was used to calculate the correlation between pathological parameters and the OTUB1-isoform 2 mRNA levels. Kaplan-Meier and Cox proportional hazards analyses were used to analyze the overall survival (OS) and disease-free survival (DFS) rates. Nuclear and cytoplasmic RNAs were isolated to detect the subcellular localization of OTUB1-isoform 2. We also assessed whether overexpression of OTUB1-isoform 2 influenced in vitro cell proliferation, cell cycle progression, tumor cell invasion and migration, as well as in vivo nude mouse xenograft and metastasis models.

resultsThe OTUB1-isoform 2 expression levels were higher in the gastric cancer samples than in the paratumorous gland samples. OTUB1-isoform 2 expression levels tightly correlated with tumor size, lymph node metastasis and TNM staging. Higher OTUB1-isoform 2 expression levels led to significantly poorer OS and DFS rates, and a multivariate analysis revealed that OTUB1-isoform 2 was an independent risk factor for DFS. OTUB1-isoform 2 was predominantly localized in the cell nucleus. Ectopic overexpression of OTUB1-isoform 2 in gastric cancer cells stimulated proliferation by inducing G1-S transition, suppression of cell apoptosis and promotion of tumor cell invasion and migration. Finally, OTUB1-isoform 2 overexpression promoted tumor growth and tumor metastasis in nude mice models.

conclusionsOur study suggests that OTUB1-isoform 2 independently predicts poor prognosis and promotes tumor progression in gastric cancer. The non-coding RNA OTUB1-isoform 2 should be targeted in future molecular therapies.
