Quercetin promotes the proliferation, migration, and invasion of trophoblast cells by regulating the miR-149-3p/AKT1 axis.
Article in The Kaohsiung journal of medical sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Recurrent spontaneous abortion (RSA) has a complex pathogenesis with an increasing prevalence and is one of the most intractable clinical challenges in the field of reproductive medicine. Quercetin (QCT) is an effective active ingredient extracted from Semen Cuscutae and Herba Taxilli used in traditional Chinese medicine for tonifyng the kidneys and promoting fetal restoration. Although QCT helps improve adverse pregnancy outcomes, the specific mechanism remains unclear. The trophoblast cell line HTR-8/SVneo cultured in vitro was treated with different concentrations of QCT, and the cell counting kit-8 assay, wound healing assay, transwell assay, and western blotting were used to evaluate the effects and mechanisms of QCT on the proliferation, migration, and invasion of HTR-8/SVneo cells, respectively. To assess the expression levels of miR-149-3p and AKT serine/threonine kinase 1 (AKT1), quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting analysis were performed. A dual-luciferase reporter assay was used to investigate the potential regulatory relationship between miR-149-3p and AKT1. Our results showed that QCT promoted the proliferation, migration, and invasion of trophoblast cells, promoted the expression of MMP2, MMP9, and vimentin, and downregulated the expression of E-cadherin. Mechanistically, QCT downregulated the expression of miR-149-3p and upregulated the expression of AKT1, and miR-149-3p directly targets AKT1, negatively regulating its expression. Overexpression of miR-149-3p and silencing of AKT1 counteracted the promotional effects of QCT on trophoblast proliferation, migration, and invasion. Taken together, QCT regulates the migration and invasion abilities of HTR-8/SVneo cells through the miR-149-3p/AKT1 axis, which may provide a promising therapeutic approach for RSA.
