HGF knockdown suppresses ovarian cancer malignancy: insights from a transient receptor potential-related gene model.
Article in European journal of medical research, 2025. 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
backgroundOvarian carcinoma (OV) is a prevalent gynecologic malignancy. While transient receptor potential (TRP) channels are substantially correlated with tumor growth, their role in OV remains unclear. This study therefore aims to construct a comprehensive TRP-related prognostic model and analyze its association with the cell infiltration and checkpoint expression.
methodsBased on transcriptomic data from public OV databases, TRP activity scores were calculated using single-sample gene set enrichment analysis (ssGSEA), and correlated gene modules were identified through Weighted Gene Co-expression Network Analysis (WGCNA). Functional enrichment analysis was performed to elucidate underlying biological pathways. A prognostic signature was developed via machine learning algorithms, and its clinical utility was validated through construction of a nomogram integrating key clinicopathological parameters. Comprehensive immune characterization was conducted to compare microenvironmental features between risk subgroups. Finally, functional assays including cell counting kit-8 (CCK-8), wound healing, and Transwell were employed to experimentally validate the role of a candidate gene in OV progression.
resultsOf the 21 co-expression modules identified, the brown module demonstrated the strongest positive correlation with TRP scores. Functional enrichment analysis revealed that TRP-related genes were predominantly involved in immune system pathways. Using the nine identified genes, a risk model was developed, and Riskscore was employed to categorize patients into high- and low-risk groups. Overall survival (OS) was notably higher for patients in the OV low-risk group than for those in the high-risk group. The nomogram's findings demonstrated that the Riskscore had an independent impact on prognosis. According to immunological characterization, the low-risk group had higher levels of cellular infiltration, including activated B cells and activated CD4 T cells. High-risk group had low expressions of immune checkpoint genes, including LAG3, CD274, and CD27. In vitro tests showed that HGF knockdown markedly reduced the viability, motility, and invasion of OV cells.
conclusionThe TRP-related gene signature constructed in this study predicts the prognosis and immune microenvironment status of OV patients, providing a new perspective for prognosis assessment and targeted therapy in OV.
