For example, N-FOXP1 protein is up-regulated in diffuse large B-cell lymphoma (DLBCL) and extranodal marginal zone or mucosa-associated lymphoid tissue (MALT) lymphoma [7], while loss of N-FOXP1 expression characterizes malignancy in certain solid tumors, including endometrial and prostate tumors as well as familial and sporadic breast cancer [3, 8–10]. This evidence concerns the gene FOXP1 and diffuse large B-cell lymphoma.
