In a public pan‐cancer B cell dataset [16], IREB2 was enriched in memory and cycling B cells, positively associated with (Figure 6I,J), positively associated with functional/prognostic markers (CD19, CD80, CD86, FCRL4, FAS), and negatively with poor‐prognosis genes (IGHG1, IGHA1, CD27), consistent across lung cancer subsets (Figure 6I–O). This evidence concerns the gene IREB2 and lung cancer.
