DAZAP1 overexpression promotes growth of HCC cell lines: a primary study using CEUS.
Article in Clinical & translational oncology : official publication of the Federation of Spanish Oncology Societies and of the National Cancer Institute of Mexico, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
purposeHepatocellular carcinoma (HCC) is one of the most common types of hepatic carcinoma. The overall prognosis is poor. DAZAP1, a regulator of alternative splicing (AS) events, may participate in tumor growth.
methodsWe collected 105 HCC patients and tissue samples from the Department of Hepatological Surgery in the Second Affiliated Hospital of Qiqihar Medical University. TCGA datasets were downloaded and operated using the R project. DAZAP1 expressions were examined by quantitative RT-PCR and western blotting. CCK8 assay was used to investigate the cell proliferation, and transwell assay was employed to examine the ability of migration and invasion in vitro. Contrast-enhanced ultrasound (CEUS) was used to evaluate images and parameters of the tumor.
resultsDAZAP1 is highly expressed in the tissue samples of HCC. The peak intensity (PI) and area under the curve (AUC) of the tumor is higher than that of liver parenchyma, and correlated with high DAZAP1 expression. Parameters of CEUS in the tumor are correlated with TNM stage, tumor size, and vascularity. High DAZAP1 expression correlates with a shorter survival time and advanced histologic grade (G3-G4). Bioinformatical analysis revealed that downregulation of DAZAP1 identified differentiated expressed genes (DEGs) involved in the tumor growth process.
conclusionsDAZAP1 is highly expressed in hepatic carcinoma and related to the blood flow, and high DAZAP1 expression predicts poor prognosis. DAZAP1 may promote liver carcinoma cell proliferation, migration, and invasion of HEPG2 cells. CEUS parameters are related to the high DAZAP1 expression, and will help to differentiate the HCC tumor.
