Hsa_circ_0013561 promotes epithelial-mesenchymal transition and tumor progression by regulating ANXA2 via miR-23b-3p in ovarian cancer.
Article in Cancer gene therapy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Our preliminary experiment discovered that hsa_circ_0013561 was aberrantly expressed in OC. However, the underlying mechanism is unclear. The expression of hsa_circ_0013561 in OC cells and tissues was detected by RT-qPCR and fluorescence in situ hybridization. The effects of hsa_circ_0013561 on the proliferation and metastasis of OC were explored by functional experiments such as cell counting kit-8, transwell, and tumor xenograft models. To mechanistically understand the regulatory role of hsa_circ_0013561, bioinformatics analysis, Western blot, luciferase reporter assay, and a series of rescue experiments were applied. We found that the hsa_circ_0013561 expression was elevated in OC cells and tissues, and was correlated with metastasis formation. Downregulation of hsa_circ_0013561 suppressed the proliferation and migration of OC cells both in vitro and in vivo. Regarding the interactions of hsa_circ_0013561, the luciferase reporter assay verified that miR-23b-3p and Annexin A2 (ANXA2) were its downstream targets. MiR-23b-3p inhibition or ANXA2 overexpression reversed OC cell proliferation, migration, and epithelial-mesenchymal transition (EMT) post-hsa_circ_0013561 silencing. Moreover, ANXA2 overexpression also reversed OC cell migration, proliferation, and EMT after miR-23b-3p upregulation. Our data suggest that hsa_circ_0013561 increases the expression of ANXA2 by regulating miR-23b-3p competitively, resulting in EMT and metastasis of OC. Thus, hsa_circ_0013561 may serve as a novel oncogenic biomarker for OC progression.
