1 Based on our previous evidence that tumour necrosis factor-alpha (TNF-alpha) acts as an endogenous tumour promoter on BALB/3T3 cells initiated with 3-methylcholanthrene, we found that morphine dose-dependently inhibited TnF-alpha release from KATO III cells (IC50, 5.6 mM) and also from BALB/3T3 cells (IC50, 1.3 mM) induced by okadaic acid, one of the non-TPA type tumour promoters.

3 Moreover, morphine inhibited expression of TNF-alpha mRNA in BALB/3T3 cells (IC50, 1.6 mM), but not expression of early response genes. Morphine tumor necrosis factor Mus musculus
