Similarly, in BLCA samples, D2 remained uncorrelated with both GATA3 (Pearson correlation coefficient, rho, ρ = −0.08, Fig. 3f) and UPK3A (Pearson correlation coefficient, rho, ρ = −0.09, Fig. 3f), indicating that D2 upregulation occurs independently of the classical urothelial markers. This evidence concerns the gene UPK3A and bladder transitional cell carcinoma.
