The survival rate was reduced to 17% of the vehicle treated control and this was thought due to the low viability rate (18. RSG) determined during the expression period (Table 3. The MF result for this concentration however was below the accepted criteria required to be positive. Kratom Herb Drug Test Danbury in view of these findings it is likely that the involvement of other chemicals that are present in the MSE most probably explained why metabolic activation by S9 increased MSE toxicity.

Many agents are currently known to induce cell death via caspase independent pathways as described above such as campothecin doxorubicin and paclitaxel. The necrotic type of cell death induced by MSE which is morphologically seen in cell lines such as MCL-5 and HEK 293 cells could not be confirmed biochemically due to time limitations. Unlike MSE MIT treated SH-SY5Y cells have shown a different mechanism of cell death in which there was an involvement of caspases 3 and 7. This is consistent with the immmunoblot finding which indicates mitragyna speciosa plants for sale florida that p53 and p21 proteins were marginally expressed even at high doses of MIT. These findings indicate that MIT treated SH-SY5Y cells may execute cell death via an apoptosis pathway. If time had permitted more detailed examination of the involvement of caspases and other apoptosis-related proteins in MIT treated cells would have been desirable.
The incubation of anti-oxidant NAC 30 minutes prior to adding H202 appears to reduce the ROS production. Interestingly both high doses of MSE and MIT appeared similar to control groups and indicate that there was no ROS generation in this cell line. Another important microscopic observation was made after the final readings at the 1 hr time point which showed that all maeng da kratom feeling cells in the Control group appeared rounded and floating in the middle of the well.
M) was then added to the wells under subdued lighting and NAC was also added to appropriate wells. C (5% CO2) for 30 minutes. As the addition of DCFH-DA dye led to precipitation as seen in the preliminary experiment after 30 min the cultured solutions were aspirated and fresh PBS (1 ml) was added to each well prior to adding the test compounds kratom sellers mount ida (H202 MSE and MIT).

The effect of MIT on the expression of p53 was also assessed. MIT has demonstrated weak toxicity effects compared to MSE. As anticipated the experiments clearly showed that p53 was still being expressed in MIT treated groups and in control group but down regulated with time- dependant manner. M) the same pattern of p53 down regulations was seen as with the higher dose of MSE:
- However as shown by MSE treated groups in the absence of S9 MSE even at highest dose administered did not show any toxic effects
- The cell cycle control system has been identified as a series of proteins (e

. The next experiment was carried out to further investigate if there was a correlation between p53 changes and its target gene p21 in response to MSE and MIT treatment. The control and low dose groups however did express p21 protein consistent with Kratom Herb Drug Test Danbury the p53 expression. In the parallel experiment with MIT again p21 was expressed in a time-dependant manner that correlated with p53 expression.
Morphologically after MSE insult SH-SY5Y cells appeared to die via apoptosislike cell death whereas MCL-5 and HEK 293 cells show predominantly a necrotic type of cell death. Biochemical investigations confirmed that MSE induced SH-SY5Y cell death independent of p53 or caspases therefore the mechanism of apoptotic-like morphology features is not entirely clear however a few possible mechanisms for this type of cell death can be proposed. MIT induced cell death in SH-SY5Y cells appeared to be associated with p53 and caspasesdependant pathway however lacking morphological examinations restricts the confirmation of this finding.
