PGP and diffuse large B-cell lymphoma: As illustrated in Figure 5a–i, strong correlations were determined between survivin and either Bcl-2 (Figure 5a,d,g) or MRP1/ABCC1 expression (%) (Figure 5b,e,h), p < 0.001, respectively, and moderate correlations with either P-gp or BRCP/ABCG2 (p < 0.05) (Figure 5c,f,i) in all DLBCL groups.
