In contrast, in cancer cells, BTZ downregulates the NF‐κB dependent induction of IL‐6 in bone marrow stromal cells (BMSCs) triggered by MM cell binding and revokes TNF‐α‐induced upregulation of adhesion molecules on MM cells and BMSCs and also inhibits MM cell to BMSC binding [20]. The gene discussed is TNF; the disease is Miyoshi myopathy.
