Downregulation of ferroptosis-related Genes can regulate the invasion and migration of osteosarcoma cells.
Article in Scientific reports, 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
Osteosarcoma (OS) is a prevalent form of bone cancer among younger people, particularly children and adolescents. Ferroptosis is a non-apoptotic cell death identified by increased levels of iron-dependent lipid peroxidation. This study was designed to develop a prognostic model based on differentially expressed genes (DEGs) associated with ferroptosis and examined the functions of ferroptosis-related genes (FRGs) in OS cells. Gene expression profiles in OS were retrieved from TARGET and GEO databases, while GTEx provided data for healthy tissues. Prognostic genes were identified through bioinformatics analysis and data integration. In vitro experiments, cell cultures, qRT-PCR, immunohistochemistry (IHC), cell transfection, Edu assays, DHE assays, migration, and invasion assays validated the prognostic model and explored the functional role of FRGs in OS cells. Univariate Cox regression analysis demonstrated that 12 DEGs were differentially expressed. Based on four FRGs in OS constructed a risk-scoring model. The high-risk (HR) group showed a considerably lower OS rate than the low-risk (LR) group (p < 0.001 in the TARGET and p < 0.05 in the GSE21257 cohorts). A risk score was validated as an independent predictive factor for OS via multivariate Cox regression. Functional analysis shows that these FRGs affect the occurrence of ferroptosis by influencing the intracellular ROS levels and play a regulatory role in the proliferation, migration, and infiltration of OS cells. The findings suggested that four FRGs demonstrate significant prognostic value in OS, offering potential insights into novel therapeutic targets for OS treatment.
