It is a known paradox that many TGF beta 1-producing tumor cells are resistant to this, otherwise, inhibitory cytokine. In a lymphoma of B-cell origin exogenous TGF beta 1 was able to induce apoptosis, suggesting that the apoptosis program can be switched on. The apoptosis induction was independent of the death receptors but dependent on mitochondrial pathway and caspase-3. Probably due to the weak starting signal, caspase-3 further activated
caspase-8
which, through the Bid cleavage and Bax translocation into the mitochondria, provided an autocatalytic support for the apoptotic program. There is a time-gat between the early activation of Smad-dependent
TIEG
and the accumulation of ROS, therefore other participants that start the increase in mitochondrial membrane permeability should be identified.
