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

purposeThis work was initiated to offer solid evidence regarding the expression and roles of long noncoding RNA (lncRNA) CCDC144NL-AS1 in hepatocellular carcinoma (HCC). PATIENTS AND

methodsCell Counting Kit-8 assay, flow cytometric analysis, and invasion assays were used to explore the malignant biological characteristics of cells. Immunohistochemistry (IHC), Western blotting analysis, and real-time quantitative PCR (RT-qPCR) were used to analyze the expression level of related proteins and nucleic acids. Bl6/Rag2/GammaC double knockout mice were used for HCC modeling to address the therapeutic value of CCDC144NL-AS1.

resultsCCDC144NL-AS1 was significantly upregulated in HCC tissue and had a marked relationship with the 5-year prognosis. In vitro study revealed that CCDC144NL-AS1 was highly expressed in HCC cell line MHCC97H but lowly expressed in normal hepatic cell line L02. Overexpression of CCDC144NL-AS1 in L02 enhanced the invasion and proliferation abilities of cells but inhibited the apoptosis rate. Knockdown of CCDC144NL-AS1 in MHCC97H weakened the invasion and proliferation abilities of cells but increased the apoptosis rate. CCDC144NL-AS1 was found to sponge miR-940 to induce the expression of WD repeat domain 5 (WDR5). ChIP-seq analysis identified that matrix metalloproteinase (MMP) 2, MMP9, and cyclin-dependent kinase (CDK) 1, CDK2, and CDK4 were all targets of WDR5. The recruitment of WDR5 to the promoter of these target genes upregulated the histone H3 lysine 4 trimethylation (H3K4me3) level in these regions and further induced the transcription of MMP2, MMP9, CDK1, CDK2, and CDK4. In vivo study revealed that compared to the normal liver tissue, CCDC144NL-AS1, WDR5, MMP2, MMP9, CDK1, CDK2, and CDK4 were all significantly upregulated in HCC tissue from the same mouse, while miR-940 was decreased. Besides, knockdown of CCDC144NL-AS1 or WDR5 or overexpression of miR-940 could all inhibit tumor growth.

conclusionCCDC144NL-AS1 drives HCC development by inducing MMP2/MMP9 and CDK1/CDK2/CDK4 expressions through miR-940/WDR5-regulated epigenetic pathway.
