Therefore, in this study, we selected and validated eight differentially expressed m7G-related lncRNAs with prognostic values in BC, namely, BAIAP2-DT, COL4A2-AS1, FARP1-AS1, RERE-AS1, NDUFA6-DT, TFAP2A-AS1, LINC00115, and MIR302CHG, created m7G-LPS, and conducted a combined analysis of the clinicopathological characteristics, tumor immune cell infiltration, and TMB to examine the role of m7G-related lncRNAs in BC. This evidence concerns the gene NDUFA6 and breast cancer.
