In the present work, by TMA immunostaining analyses, using cutoff criteria based on the median percentage of positive cells, we confirmed the existence of a negative correlation between PATZ1 and BCL6 in DLBCL, indicating that the upregulation of BCL6 in this NHL sub-group could be linked to a downregulation of PATZ1. Here, PATZ1 is linked to diffuse large B-cell lymphoma.
