After identifying that LINC00426 is associated with immune-related and cancer-related processes, we used CIBERSORTx to estimate the abundance of 22 tumor-infiltrating immune cell populations (Chen C. et al., 2018; Newman et al., 2019) in groups of patients with low and high expression of LINC00426 in the PAM50 LB subtype from the BRCA-TCGA cohort. Here, LINC00426 is linked to cancer.
