Role and underlying mechanisms of miR‑200 family in breast cancer (Review).
Review in International journal of oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Βreast cancer (BC) is the most common malignant tumor among women. Its significant heterogeneity and complex molecular mechanisms pose major clinical challenges, including limited therapeutic efficacy and drug resistance. Recently, microRNAs (miRs) have been recognized as key post‑transcriptional regulators involved in tumorigenesis and tumor progression through multiple pathways. Among these, the miR‑200 family (miR‑200a, miR‑200b, miR‑200c, miR‑429 and miR‑141) has attracted considerable attention due to its pivotal role in BC. The present review systematically summarizes the genomic characteristics, expression regulation mechanisms and biological functions of the miR‑200 family in BC. Special emphasis is given to their roles in epithelial‑mesenchymal transition, cell proliferation, apoptosis, maintenance of stemness, and remodeling of the tumor microenvironment. Furthermore, members of the miR‑200 family have potential as diagnostic and prognostic biomarkers and are closely linked to chemotherapy resistance. The present review aims to provide novel insights and a theoretical foundation for the diagnosis, treatment, and deeper investigation of BC by comprehensively examining the functional mechanisms of the miR‑200.
