Clinical correlation between activated NF-κB and noncanonical Hh signaling pathways. (A) Immunofluorescence analysis of p65 and GLI1 in non-neoplastic lymph nodes and DLBCL tumors. Non-neoplastic lymph nodes (controls) and DLBCL tissue sections were stained with GLI1 (red) and p65 (green) antibodies. (B) The diagram shows the correlation between GLI1 and p65-integrated nuclear density expression (percentage) in GCB (n = 16) and ABC (n = 15) DLBCL subtypes.
