CircTADA2A up-regulates MAPK8 by targeting MiR-214-3p and recruiting EIF4A3 to promote the invasion and migration of non-small cell lung cancer cells.

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
backgroundNon-small cell lung cancer (NSCLC) occupies 87% of all lung cancer cases. Due to delayed diagnosis, the prognosis of NSCLC is unfavorable. To improve the survival of patients with NSCLC, more effective therapeutic targets urgently need to be identified. Recently, circular RNAs (circRNAs) have been revealed to play a crucial role in NSCLC progression. PURPOSE: This research focused on the influence of circTADA2A on the malignant phenotype of NSCLC cells and its in-depth regulatory mechanisms.
methodsRT-qPCR and western blot assays were done to examine the level of gene/protein of interest. Wound healing and transwell assays were conducted to monitor the migration and invasion of NSCLC cells. Bioinformatics tools and mechanistic assays were utilized to delve into the underlying mechanism of circTADA2A in NSCLC cells.
resultsThe results demonstrated that circTADA2A presented a high expression in NSCLC. CircTADA2A knockdown was revealed to hamper migration and invasion of NSCLC cells. Mechanistically, circTADA2A elevated MAPK8 expression through sequestering miR-214-3p and recruiting EIF4A3.
conclusionCircTADA2A enhances MAPK8 expression by serving as a miR-214-3p sponge and EIF4A3 decoy, consequently promoting invasion and migration of NSCLC cells.
