MicroRNA-543 controls pancreatic cancer development by LINC00847-microRNA-543-STK31 axis.
Article in Journal of gastrointestinal oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Background: Pancreatic cancer (PC) is one of the most malignant cancers of the gastrointestinal tract. However, the study of targeted therapy research in PC is not very thorough. Therefore, targeted molecular markers are needed to aid in the diagnosis and treatment of PC. Methods: In our research, we investigated the biological functions and molecular mechanism of microRNA-543 in PC. Western blotting (WB) and quantitative real-time polymerase chain reaction (qRT-PCR) were performed to analyze the transcription and protein expression of microRNA-543, Serine/threonine kinase 31 (STK31), and LINC00847 in BxPC-3 and PANC-1 cells. Subsequently, Cell Counting Kit-8 (CCK-8), Transwell, colony formation, and flow cytometry (FCM) assays were utilized to evaluate cell growth, migration, invasion, and apoptosis. WB and fluorescence in-situ hybridization (FISH) were used to evaluate the epithelial-mesenchymal transition (EMT) process and subcellular localization. RNA immunoprecipitation (RIP), double luciferase reporter, and RNA-pull down assays were performed to determine the targeting relationship between microRNA-543 and STK31 or microRNA-543 and LINC00847. Results: While microRNA-543 expression was discovered to be low in PC, LINC00847 and STK31 were overexpressed at significant levels. MicroRNA-543 knockdown dramatically increased PC cell growth, invasion, metastasis, and EMT, as well as decreased apoptosis in functional studies. Furthermore, microRNA-543 and STK31 were found to be mutual targets. LINC00847 acted as a molecular sponge for microRNA-543 and a competitive endogenous RNA (ceRNA) for STK31, thereby increasing STK-31 transcription. Conclusions: Our results suggest that microRNA-543, through the LINC00847/microRNA-543/STK31 axis, plays a role in the development of PC as a tumor suppressor. As a result, microRNA-543 may prove to be an effective diagnostic and therapeutic target for PC.
