Figure 7. Cell death in UMUC-6 from AZ58 is mediated through a TNF-α-independent mechanism. (A) The effects on UMUC-6 of chemotherapy and AZ58 were not mitigated by the TNF-α blocking antibody. (B) Representative images of IHC for TNF-α demonstrate no difference in expression between treatment conditions. (C) Ennumeration with cell counting confirms the lack of a statistical difference in TNF-α expression.
