FIGURE 2 | (A) The network between necroptosis-related genes and lncRNAs (correlation coeffcients >0.4 and p < 0.001). (B) The prognostic necroptosis-related lncRNAs extracted by univariate Cox regression analysis. (C) . The heatmap that showed the expression pro fi les of 46 prognostic lncRNAs, which showed signi fi cant difference between normal and cancer tissues. (D) The 10-fold cross-validation for variable selection in the LASSO model. (E) The LASSO coeffcient pro fi le of 22 necroptosis-related lncRNAs. (F) Correlation analysis between risk groups and clinical features. (G) Expression of the 22 NRlncRNAs in the model between normal tissues and BRCA tissues. (H) The value of logFC of the 22 NRlncRNAs. (I – L) qRT-PCR results showing the expression of lncRNAs in the normal breast and fi ve breast cancer cell lines. *P<0.05; **P<0.01;
