Since previous studies suggest that some lncRNAs could be related with these immune-functional markers in cancer (Peng et al., 2020; Salama et al., 2020; Samir et al., 2021), we evaluated whether the LINC00426 expression correlates with ICGs (PDCD1, PDCD1LG2, CD274, CTLA4, LAG3, TIGIT and IDO1) and CARGs (GZMA, GZMB and PRF1) expression in the PAM50 LB subtype from the BRCA-TCGA cohort. Here, LAG3 is linked to cancer.
