MiR-590-5p promotes cisplatin resistance via targeting hMSH2 in ovarian cancer.
Article in Molecular biology reports, 2023. 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
objectiveThe mechanisms of ovarian cancer generate chemotherapy resistance are still unclear. This study aimed to explore the role of microRNA (miR)-590-5p in regulating hMSH2 expression and cisplatin resistance in ovarian cancer.
methodsMiR-590-5p was identified as a regulator of hMSH2 with miRDB database and Target Scan database. Then cisplatin sensitive cell line (SKOV3) and resistant cell line (SKOV3-DDP) of ovarian cancer were cultured for cell functional assay and molecular biology assay. The expression levels of MiR-590-5p and hMSH2 were compared between the two cell lines. Dual luciferase reporter assay was used to verify the targeted regulatory relationship between miR-590-5p and hMSH2. CCK-8 assay and cell apoptosis assay were utilized to assess the role of MiR-590-5p and hMSH2 in cell viability under cisplatin.
resultsThe expression of hMSH2 was significantly decreased, and miR-590-5p was significantly up-regulated in SKOV3-DDP. Up-regulation of hMSH2 weakened the viability of SKOV3 and SKOV3-DDP cell under cisplatin. Transfection with miR‑590-5p mimics reduced the expression of hMSH2 and enhanced the viability of ovarian cancer cells under cisplatin, whereas inhibition of miR‑590-5p increased the expression of hMSH2, and decreased ovarian cancer cells' viability under cisplatin. Furthermore, luciferase reporter assay showed that hMSH2 was a direct target of miR-590-5p.
conclusionThe present study demonstrates that miR‑590-5p promotes cisplatin resistance of ovarian cancer via negatively regulating hMSH2 expression. Inhibition of miR‑590-5p decreases ovarian cancer cells' viability under cisplatin. Thus miR‑590-5p and hMSH2 may serve as therapeutic targets for cisplatin resistant ovarian cancer.
