Parallel experiments were carried out to assess the effects of MIT on the expression of p21 protein. In the previous section it was noted that there were no major differences in p53 band intensity over the dose range tested compared to the control group implying that MIT does not induce the loss of protein as seen in the MSE treated cells. As with the p53 effects noted previously MIT had little effect on p21 levels (Fig. P21 levels of MSE treated SH-SY5Y cells at different time points (6 12 24 and 48 hr). The indo kratom stem powder blots were representatives of duplicate experiments. P21 levels of MIT treated SH-SY5Y cells at different time points

Interestingly in the absence of S9 MIT showed dose-dependant cytotoxicity (low RSG) on its own. The preliminary data shown here are the results taken after 2 days expression period prior to plating. There was no significant difference in cell numbers compared to negative control or positive control groups; however based on the formula which takes into account the suspension growth for two days culturing period low dose-dependant RSG was calculated. The low suspension growth was noted even after 24 hr post treatment (data not shown). Thus all concentration tested in this group were chosen for plating for the final step of red borneo kratom effects assessment. As shown in the table 3. MLA results for MIT in the presence or absence of rat liver S9 show no evidence of genotoxicity.

I therefore predicted that opiate receptor Kratom Euphoric Effects Kinzua antagonists would protect against MSE and MIT induced cell death. MSE toxicity Kratom Euphoric Effects Kinzua both in acute and longer term treatment. Thus it is suggested that apart from MIT there are other chemicals present in the leaves of Mitragyna specioa Korth contributing to the MSE cytotoxicity. A summary of the cytotoxic events leading to MSE or MIT induced SH-SY5Y cell death as discussed above are shown in fig.
Since in my present study the apoptotic-like cell death induced by MSE was suggested to be caspasesindependent an investigation looking at generation of ROS in mediating the apoptotic events was carried out. Unfortunately the results in my study showed that there was no ROS generation upon treatment with high doses of MSE or MIT. During the ROS study another interesting observation was made specifically that MSE co-treatment with NAC appeared to protect the cells from death and that chemicals present in the MSE emphasised this effect.
