The recent review by Zhang et al (2008) stated that morphine for instance induces neurotoxicity and apoptosis after chronic use and heroin also induced apoptotic cell death via mitochondrial malfunction caspase activation leading to PARP cleavage and DNA fragmentation. Thus MIT may show a similar trend of apoptotic cell death as opiates but confirmation of this finding requires further investigations. MSE as death appears to be caspase-independent and thus chemicals other than MIT present in MSE appear to complicate the interpretation of my biochemical findings. Despite having a crucial role for cellular energy metabolism mitochondria are also known to be a key player in cell death.
Thirty thousand (30000) cells were analysed for each treatment using FLOW JO 8. Caspases enzyme assay Caspases play an important role in mammalian apoptosis. In this part of the study two initiator caspases caspases-8 and 9 Premium Bali Kratom Review and two executioner caspases 3 and 7 were used to investigate the mechanism of caspase activation in MSE and MIT induced cell death. In parallel caspase inhibitors were employed to confirm the outcome of the former assays. The caspase-8 and caspase-9 colorimetric assays purchased from Invitrogen U.
Annexin V conjugate was measured at 650 nm excitation and 665 nm emission and 7-AAD at 488 nm excitation and 620 nm emission.

In this part of the study what is kratom side effects saint ann two initiator caspases caspases-8 and 9 and two executioner caspases 3 and 7 were used to investigate the mechanism of caspase activation in MSE and MIT induced cell death.

Scoring kratom shop ch the plates After the incubation period all the plates for viability assessment were scored Premium Bali Kratom Review using a modified mirror box for the absence or presence of colonies in each well. The numbers of negative wells for viability plates and positive wells for mutant plates were also recorded. Test Acceptance
Criteria and Evaluation of the Results Following the protocols obtained from GlaxoSmithKline Company (Ware U. K) the assay was accepted based on the measurement of cytotoxicity by relative total growth (RTG) which reduced to approximately 10-20% when compared to concurrent vehicle control. The mean vehicle control value for mutant frequency (MF) are between 50-170 x 10-6 The mean cloning efficiency is between 65-120%. The mean suspension growth are between 8-32 on day 2 (following 3 hr treatment with S9) After exclusion of obvious outliers at least 2 acceptable vehicle controls cultures remain.
The same peak was also observed in MSE. It was believed to be due to the incomplete removal of chloroform during the preparation of MSE. With this finding a concern arises whether this minor contamination would affect the toxicity of MSE or MIT (from Japan) in the cell based studies.

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.
