Varying degrees of BATF3 expression were observed in primary mediastinal large B-cell lymphoma (PMBL) (n = 14/15), diffuse large B-cell lymphoma (DLBCL) (n = 7/22), T-cell/histiocyte-rich large B-cell lymphoma (THRLBL) (n = 3/3), follicular lymphoma (FL) (n = 5/22), chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL) (n =1/15), plasma cell neoplasm (PCN) (n = 1/15), peripheral T-cell lymphoma (PTCL) (n = 6/12), intestinal T-cell lymphoma (ITCL) (n = 2/2) and NLPHL (n = 7/16) (Figure 1). This evidence concerns the gene BATF3 and B-cell chronic lymphocytic leukemia.
