This is in agreement with both previous gene expression data [1] and current RT-PCR data on DLBCL cell lines (Figure 2) and thus confirms that the cytoplasmic staining seen in IHC for DLBCL and other non-MCLs [1,3-5,18] should not be considered to be specific for SOX11. Here, SOX11 is linked to diffuse large B-cell lymphoma.
