Reactive Oxygen Species-Mediated Cezanne Inactivation by Oxidation of its Catalytic Cysteine Residue in Hepatocellular Carcinoma.
Article in Oncology research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Cysteine oxidation occurs at the active site of deubiquitinases (DUBs) during many biologic signaling cascades. Here we report that hepatocellular carcinoma cells (HCCs) generated higher levels of endogenous reactive oxygen species (ROS). This elevated ROS production was inhibited by NADPH oxidase inhibitor diphenylene iodonium (DPI) and mitochondria electron chain inhibitor rotenone in HCC cells. Moreover, we found that H₂O₂ could activate NF-κB-dependent inflammatory effect through increased induction of matrix metalloproteinase 2 (MMP2), MMP9, and intercellular adhesion molecule 1 (ICAM1) expression levels. In addition, we found that H₂O₂ could prolong NF-κB activation by suppressing the negative regulatory functions of Cezanne in HCC cells. Ubiquitin-derived thiol-reactive probe (HA-UbVME) assay and biotin-tagged 1,3-cyclohexadione derivative (DCP-Bio1) assay showed that H₂O₂ has the capacity to inhibit the catalytic activity of Cezanne, and the reducing agent, DTT, could reactivate the Cezanne deubiquitinating enzyme activity. Taken all together, these findings demonstrated an important role for oxidation of Cezanne by ROS in regulation of the inflammatory effect of hepatocellular carcinoma.
