We also found that B cell related proteins (CD20, BAD, BCL-2, CD27, BIM) were most highly expressed in the stromal compartments (Fig. 2E) while expression of lymphocyte-related markers (CD3, CD8, CD4, Tim-3) were elevated in tumor compartments (Fig. 2F, Additional file 1: Table S5). The gene discussed is PPIB; the disease is neoplasm.
