Low expression of AQP9 and its value in hepatocellular carcinoma.
Article in Translational cancer research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundThe mortality rate for liver cancer is high worldwide. The etiology of liver cancer has altered with the high incidence rate of non-alcoholic fatty liver disease (NAFLD) although effective vaccination strategies have been developed. Therefore, it is important to discover new biomarkers for diagnosis and prognosis. Aquaporin 9 (AQP9) has been reported in some cancers, especially in liver cancer, although its role in this malignancy remains to be clarified. In this study, we conducted a bioinformatics analysis to clarify the function of AQP9 in liver cancer.
methodsImmunohistochemistry, real-time qPCR, western blot analysis were applied to detect AQP9 expression in tissue samples or cells. Online databases were used to analyze the correlation of AQP9 expression and clinical factors. LinkedOmics and gene set enrichment analysis (GSEA) were used to analyze the functional network of AQP9 in hepatocellular carcinoma (HCC). Four authoritative databases were used to predict the candidate microRNAs that bind to AQP9. Finally, we used the Tumor Immune Estimation Resource (TIMER) to assess the correlation of AQP9 and immune cell infiltration in HCC.
resultsAll analysis were revealed AQP9 is significantly decreased in HCC tissues and cells. AQP9 was negatively correlated with different tumor stage, grade, and weight, as well as lymph node metastasis, sex, and histological subtypes. AQP9 can be used to predict the prognosis of HCC patients. GSEA revealed that AQP9 was significantly involved in most significant hallmark pathways. LinkedOmics was used to analyze the relationship of AQP9 with Gene Ontology and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Mechanistically, mir-23a-3p and mir-330-3p may downregulate AQP9 expression in HCC. AQP9 was found to be specifically correlated with immune cell infiltration and play a major role in the liver cancer microenvironment.
conclusionsIn this study, we found that AQP9 was significantly decreased in HCC, with low AQP9 levels indicating a poor outcome. GSEA analysis and LinkedOmics revealed that AQP9 was significantly involved in the most significant hallmarks pathways. Mir-23a-3p and mir-330-3p may inhibit AQP9 expression in HCC. Our results also suggest that AQP9 is important in tumor immunity in the liver cancer.
