Surprisingly, despite a clear activation of the non-canonical NF-κB pathway in the cancer cells tested, they did not secrete the chemokines CXCL12, CXCL13, CCL19 and CCL21, known to be induced as a consequence of activation of this signaling pathway upon LTβR stimulation of other cell types [12]. This evidence concerns the gene CXCL12 and cancer.
