HIP1R and diffuse large B-cell lymphoma: The frequency of FOXP2 expression was also higher in DLBCL with a FOXP1hiHIP1Rlo phenotype (DLBCL with FOXP1 short isoforms potentially capable of transcriptionally repressing its direct target gene HIP1R) than those with FOXP1lo/HIP1Rhi expression (P = 0.0162: Figure 4B).
