Moreover, the correlations between single lncRNAs in the PRlncSig and tumor-infiltrating immune cells were further explored using the CIBERSORT algorithm (Supplementary Figure 3C), and the results showed that LINC01224 had significant positive correlations with T follicular helper cells, memory-activated CD4 T cells, and resting dendritic cells, whereas it showed a significant negative correlation with activated NK cells. This evidence concerns the gene CD4 and neoplasm.
