Genomic landscape of endometrial polyps.
Article in Genome medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundEndometrial polyps are common, localized overgrowths of endometrial glands and stroma that protrude into the uterine cavity. These tumor-like lesions can cause symptoms like abnormal uterine bleeding and infertility, and they may undergo malignant transformation. The etiology of endometrial polyps remains largely unknown.
methodsHere, we conducted whole-genome sequencing and global gene expression profiling on 23 polyps. Major findings were validated with targeted DNA (Sanger sequencing) and protein (immunohistochemistry) level analyses. Sanger sequencing was also utilized to validate the observed novel alterations in an additional set of 54 polyp samples.
resultsThe most common alterations were chromosomal rearrangements affecting HMGA1 and HMGA2, identified in 74% (17/23) of the polyps. These rearrangements involved LRMDA, RAD51B, TRAF3IP2, and 7p15.2 as recurrent rearrangement partners. 3'RNA sequencing indicated corresponding overexpression of HMGA1 and HMGA2 as well as a downstream target PLAG1. Elevated protein level expression of HMGA1 and HMGA2 was further shown using immunohistochemistry. In addition to frequent HMGA1 and HMGA2 alterations, we found UBE2A as a novel candidate driver gene with highly specific recurrent mutations. We also identified recurrent low-allelic fraction mutations in well-established cancer genes KRAS, PIK3CA, PIK3R1, and PTEN.
conclusionsHere, we have characterized the genomic landscape of endometrial polyps. We show that chromosomal alterations affecting HMGA1 and HMGA2 are a major underlying cause for polyp development. In addition, we present UBE2A as a novel candidate gene for human tumorigenesis. Our results contribute to a better understanding of endometrial polyp development and pave the way towards the development of targeted, non-invasive treatment options.
