NFKBIA and breast cancer: Additionally, by analyzing the correlation between NFKBIA mRNA levels and the infiltration of 22 inflammatory cells in breast cancer tissues based on the TCGA dataset (Fig. 5C, D & Supplementary Fig. 5E-F), we showed that NFKBIA mRNA levels were positively correlated with infiltration levels of M1, CD4+ T cells, CD8+ T cells and naïve B cells (Fig. 5C & Supplementary Fig. 5E), whereas negatively correlated with infiltration levels of M2 cells, resting mast cells and eosinphils in breast cancer tissues based on the TCGA dataset (Fig. 5D).
