Consistently, previously published data from our group [44] showed that expression levels of NF-κB signature gene sets were elevated in adherent JeKo-1 MCL cells compared to suspension cells in the co-culture as well as mono-cultured cells, reaching the expression levels seen in mono-cultured REC-1 cells (Table S1 and Figure S1A). This evidence concerns the gene NFKB1 and mantle cell lymphoma.
