To determine the biological function of the B7-CD28 family in DLBCL, the 200 genes most strongly correlated with the B7-CD28 family (ranked by Pearson lRl) were identified in GSE10846 and GSE31312 cohort patients who were analyzed using the GPL570 platform (Figure 3). The gene discussed is CD28; the disease is diffuse large B-cell lymphoma.
