GFI1 and carcinoma: This analysis showed that mean GFI1 and TNFRSF11A mRNA expression levels within carcinoma cells were significantly higher compared to other cell types (F = 14.86, P = 1.89E-08 and F = 10.27, P = 1.11E-06), including normal epithelial cells, stromal fibroblasts and lymphocytes (Figure 3 and Table 5).
