The basic toxicology data established in the previous chapter has informed us on the potential cytotoxicity of MSE and MIT on several human cell lines which generally shows cytotoxicity with high dose. The lethal effect of the extract and major alkaloid (MIT) on the cells examined prompted the question whether cell death was accompanied by DNA damage. DNA damage as a result of endogenous sources (cellular metabolic processes) or exogenous sources (environmental factors such as chemical insult) could lead to reversible or irreversible genetic change. Based on the long term use of this plant by humans testing for its genotoxic potential using mammalian cells was thought to be more appropriate than conventional first tier testing for gene mutation in bacteria. In fact the primary first tier bacterial genetic toxicology assay the Ames Salmonella assay is incapable of detecting large scale deletion or recombination events of the mutations.

A second incubation time point at 18 hr also showed negative results. The next step was investigating the possibility of involvement of executioner caspases such as caspase 3 and 7. The executioner caspases are also known as downstream caspases as they depend on active initiator caspases for their activation by proteolytic cleavage (Srinivasula et al 2001). As anticipated there was no activation of caspases 3 and 7 activities in cells treated with high dose Kratom Withdrawal Pain Fort Wayne of MSE at both 4 hr and 18 hr incubation time points. Interestingly for MIT there was a clear significant difference of caspases 3 and 7 best way to do kratom activities at both concentrations of MIT tested. This finding suggests that the mode of the cell death of MIT treated cells is dependant on caspase 3 and 7 activation pathway. There were no significant differences in the subG1 population (apoptosis population) between treated groups (caspase 3 inhibitor caspase 8 inhibitor caspase 9 inhibitor and general caspase inhibitor treated with high dose of MSE) and the control and negative control groups.
