The Long Non-Coding RNA CASC2 Suppresses Cell Viability, Migration, and Invasion in Hepatocellular Carcinoma Cells by Directly Downregulating miR-183.
Article in Yonsei medical journal, 2019. 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
purposeHepatocellular carcinoma (HCC) is the most common malignant tumor of liver cells. Researchers have reported that cancer susceptibility candidate 2 (CASC2), a long non-coding RNA, is down-regulated in various cancers, including HCC. Our study aimed to investigate the molecular mechanism(s) of CASC2 in HCC. MATERIALS AND
methodsReal-time quantitative PCR (RT-qPCR) was used to analyze the expression of CASC2 and miR-183 in HCC tissues and cells. The viability of HCC SMMC-7721 and Huh-7 cells was detected through MTT assay. Colony formation assay was performed to assess the colony formation ability of HCC cells. The migration and invasion abilities of HCC cells were evaluated by Transwell assay. Western blot was conducted to examine levels of key Wnt/β-catenin signaling pathway factors, C-myc, cyclinD, survivin, and β-catenin. The interaction between CASC2 and miR-183 was affirmed by bioinformatics analysis and luciferase reporter assay.
resultsCASC2 was down-regulated in HCC tissues and cell lines, while miR-183 was up-regulated. The expression of miR-183 was negatively correlated with CASC2 expression in HCC tissues. Overexpression of CASC2 inhibited cell viability, colony formation, migration, and invasion in HCC cells, as well as Wnt/β-catenin signaling pathway activity. miR-183 was a downstream target of CASC2 and negatively regulated by CASC2. Introduction of miR-183 rescued CASC2-induced suppressive effects on HCC cell viability, colony formation, migration, and invasion and Wnt/β-catenin signaling.
conclusionCASC2 inhibited cell viability and the colony formation, migration, and invasion abilities of HCC cells by directly downregulating miR-183 through inactivation of the Wnt/β-catenin signaling pathway.
