The clinical significance of necroptosis(NCPS) in UVM is unclear.\nMETHODS: We first identified necroptosis genes in UVM by single-cell analysis of the GSE139829 dataset from the GEO database and weighted co-expression network analysis of TCGA data. COX regression and Lasso regression were used to construct the prognostic model. Then survival analysis, immune microenvironment analysis, and mutation analysis were carried out. Finally, cell experiments were performed to verify the role of ITPA in UVM.\nRESULT: By necroptosis-related prognostic model, UVM patients in both TCGA and GEO cohorts could be classified as high-NCPS and low-NCPS groups, with significant differences in survival time between the two groups (P<0.001). Besides, the high-NCPS group had higher levels of immune checkpoint-related gene expression, suggesting that they might be more likely to benefit from immunotherapy. The cell experiments confirmed the role of ITPA, the most significant gene in the model, in UVM. After ITPA was knocked down, the activity, proliferation, and invasion ability of the MuM-2B cell line were significantly reduced.\nCONCLUSION: Our study can provide a reference for the diagnosis and treatment of patients with UVM.", "claims": [{"id": "claim-method", "statement": "COX regression and Lasso regression were used to construct the prognostic model.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:35242144", "locator": "sections[0] \"Abstract\" paragraph 2", "quote": "COX regression and Lasso regression were used to construct the prognostic model."}], "state": "complete"}, {"id": "claim-data-access", "statement": "The original contributions presented in the study are included in the article/ Supplementary Material .
