Circular RNA circ_SKA3 enhances gastric cancer development by targeting miR-520h.
Article in Histology and histopathology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo explore the mechanisms of action of circ_SKA3 in gastric cancer (GC), which are still not fully understood.
methodsSubcellular localization assay was used to analyze the localization of circ_SKA3, and Actinomycin D assay was applied to confirm the stability of circ_SKA3. The levels of circ_SKA3, microRNA (miR)-520h, and cell division cycle 42 (CDC42) mRNA were gauged by quantitative real-time polymerase chain reaction (qRT-PCR). The protein levels of CDC42 and proliferating cell nuclear antigen (PCNA) were assessed by western blot. Cell proliferation, colony formation, cell cycle distribution, apoptosis, migration, and invasion were detected by 3-[4,5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT), 5-Ethynyl-2'-Deoxyuridine (EdU) incorporation, colony formation, flow cytometry, and transwell assays, respectively. Directed relationship between miR-520h and circ_SKA3 or CDC42 was verified by a dual-luciferase reporter assay. Mouse xenograft experiments were used to elucidate the impact of circ_SKA3 in vivo.
resultsOverexpression of circ_SKA3 was validated in GC tissues and cells. The down-regulation of circ_SKA3 suppressed proliferation, cell cycle progression, colony formation, migration, invasion, and promoted cell apoptosis in vitro, as well as weakening tumor growth in vivo. Circ_SKA3 directly bound to miR-520h, and circ_SKA3 regulated CDC42 expression through miR-520h. Circ_SKA3 exerted regulatory effects on GC cell behaviors by inhibiting miR-520h. Furthermore, CDC42 was a functional target of miR-520h in regulating GC cell behaviors.
conclusionOur findings established a strong molecular mechanism, the miR-520h/CDC42 axis, at least in part, for the oncogenic role of circ_SKA3 in GC.
