Despite having a crucial role for cellular energy metabolism mitochondria are also known to be a key player in cell death. DIABLO in completing the cell death cascade. Mitochondria have also been shown as an important factor in other caspase-independant apoptosis.
HEK 293 MCL-5 and SH-SY5Y cells were used in this analysis. The cells were cultured and maintained as described in chapter 2 section 2. The chemicals for cell cycle analysis; propidium iodide RNase triton-x100 and ethyl alcohol absolute were purchased from Sigma-Aldrich (U. TEMED) from Bio-rad laboratories (Hemel Hempstead Kratom Capsules Review Monterey U.

RNase and 0. C for 30 minutes. Samples were analysed using the Cellquest Pro software on a Becton Dickinson FACSCalibur flow cytometer.
PI was excited at 488 nm using an Argon laser and the fluorescence analysed at 620 nm. Immunoblot For this
experiment the procedure was adapted from Laemmli method (Laemmli 1970). SH-SY5Y cells were used as it was the most sensitive cell line for the toxicity effects of MSE and MIT.
PBS followed by centrifugation (1200 r. Cells were re-suspended in Annexin-binding Kratom Capsules Review Monterey buffer (10mM HEPES 150 mM NaCl and 2. M CaCl2 at pH 7. The cells were then incubated on ice for 5 minutes until data acquisition with a Becton Dickinson FACSCalibur flow cytometer using CellQuest Pro software. Annexin V conjugate was measured at 650 nm excitation and 665 nm emission and 7-AAD at 488 nm excitation and 620 nm emission. Thirty thousand (30000) cells were analysed for each treatment using FLOW JO 8. Caspases enzyme assay Caspases play an important role in mammalian apoptosis.
MSE were observed and mechanisms other than direct genotoxicity per se can lead to false positive results which are related to cytotoxicity and not genotoxicity such as events associated with apoptosis etc (ICH 1995). Such events are likely to happen once a certain concentration threshold is reached for a toxic compound. For instance in figure 2.
The mutant frequency value was determined from the derived number of mutant colonies in medium containing TFT and the number of colonies growing in nonTFT medium. The preliminary data on selection of dose range and final summary of the MLA results for the MSE and MIT are discussed below: 3. MLA for MSE As shown in table 3.
If time had permitted the role of metabolism in activating MSE and MIT would have been an important area to pursue. As part of a kratom drug side effects toxicological assessment genotoxic potential of a compound is important to characterise. A genotoxic agent is capable of causing DNA damage and if repair is unsuccessful it can lead to further major problems such as carcinogenesis.
It has been noted that plants grown in cold climates are weaker. Kratom tea can be stored in the refrigerator for several days.
Kratom extract can be stored for a couple of weeks until use.
Outside Thailand very little is known about kratom. It stimulates the body and thus increases activity. They did this mostly on a daily basis. When it was first used has not been determined since it goes too far back. In is kratom legal in delaware traditional medicine the Thai people use kratom to treat diarrhoea.
Involvement of several enzymes from lysosomal pathways such cathepsins and calpains were shown to highly correlate to apoptotic-like or even necrotic cell death (Jiang et al 2006; Yamashita et al 2003). Mitochondria which play a key role in the intrinsic pathway for apoptosis may also again be involved as apoptotic inducing factor (AIF) which is usually released after activation of Bcl-2 family acted with the EndoG protein released from plasma membrane to trigger apoptotic-like cell death ( Jiang et al 2001). 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.

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 blebbing formation) (Fig. MSE) fewer cells remained with the majority of them apoptotic with typical chromatin condensation appearance. For the HEK 293 treated cells (Fig. SH-SY5Y cells as discussed previously.
