On the other hand, it has been shown that CD40 is significantly correlated with CD40LG gene expression in 529 patients with invasive carcinoma of the breast according to the TCGA (Provisional) data set of the Agilent microarray platform (Pearson correlation: 0.53, P < 0.05) (Figure 2c). The gene discussed is CD40LG; the disease is invasive breast carcinoma.
