In the present study a possible involvement of caspase proteases both pro-apoptotic caspases (caspase 8 and 9) and executor caspases (caspase 3 and 7) were examined using commercially available kits as described in section 5. Possible involvement of pro-apoptotic caspases (8 and 9) The caspase 8 colorimetric assay performed on SH-SY5Y cell lysates indicated little difference between all MSE treated groups and control group for both 4 hr and 24 hr incubation time period (Fig. A and B).
Q3 and Q4 indicating increased of apoptotic and necrotic cells. For MCL-5 cells (Fig 5. The majority of the cells were evidently located in the Q3 and Q4 indicating the necrotic and late stage of apoptotic populations. This finding supports the cytological examinations previously noted where the cells were predominantly necrotic and in the late stage of
apoptosis. Control 1 10 50 100 250 91.
The morphology of MSE treated cells are discussed as follows. The HEK 293 and SH-SY5Y cells which were treated for 24 hr were allowed to grow for another 24 hr in fresh untreated medium prior to microscopic examination in order to allow a further doubling time. MSE) appear to have a mixture of necrotic cells ( lysis of cell membrane and lost of cell content) and apoptotic cells ( typically chromatin condensation with some Where To Buy Kratom In Fort Lauderdale Washburn blebbing formation) (Fig.
Flow cytometry analysis using Annexin V conjugate assays were employed in order to distinguish the mode of cell death upon treatment with MSE and MIT. Biochemical analysis using caspase enzymes and fluorescent dye 27dichlorofluorescein diacetate (DCFH-DA) for detecting ROS generation in live cells were also conducted to confirm the mode of cell death. And finally the possible involvement of opioid receptors in mediating the MSE and MIT cytoxicity has also been investigated. A diagram showing the extrinsic and intrinsic pathways of apoptotic cell death involving initiator caspases 8 and 9 and executioner caspases 3 and 7. The involvement of cell death receptors and its ligands p53 protein
and chemicals released from mitochondria in completing the cell death cascade are also shown.
Unfortunately difficulties in interpreting the analysis were encountered as dose-dependant shifts in dye uptake were found as in the earlier cell cycle analysis. The right shifting of the whole cell population made the interpretation of apoptotic and necrotic populations very difficult as they were not located in the anticipated quadrants thus the results green malaysian kratom forum remain inconclusive. This finding however gives strong justification to the hypothesised mechanism discussed earlier in which MSE and MIT may have the ability to change membrane permeabilisation or cause pore opening. In this study SH-SY5Y cell death induced by MSE appeared to be independent of p53 and p21 pathway. However the morphological features indicated apoptoticlike type of cell death. kratom vendor list Based on these findings it was postulated that the mechanism of cell death of SH-SY5Y cells upon MSE treatment may not follow the common intrinsic pathway which requires the activation of tumour suppressor protein p53.

Thus this information poses the question of whether the opioid receptors mediating the biological activity of the Mitragyna speciosa Korth plant may also mediate the MSE and MIT induced toxicity or cell death. I therefore predicted that opiate receptor antagonists would protect against MSE and MIT induced cell death. MSE toxicity 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. Mechanisms of MSE and MIT induced SH-SY5Y cells arrest and cell death.

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).
