Tris 2 g SDS in 500 ml distilled water pH 8. Sources and dilutions of primary and secondary antibodies for p53 and p21 protein used for the immunoblot assay. The DNA profiles of three different cell lines (HEK 293 MCL-5 and SH-SY5Y cells) treated with MSE and MIT were assessed using nucleic acid kratom herbal pain killer staining with PI and analysed with BD FacsCalibur flow cytometer in the Centre for Molecular Microbiology and Infection (CMMI) core facility unit Flowers Building South Kensington Campus.
However due to its narcotism properties it has been misused by drug addicts as an alternative to opium or to moderate the withdrawal symptoms of opium. After years of research with this plant mainly using crude alkaloid extracts its dominant alkaloid mitragynine (MIT) and congeners their analgesic properties have been confirmed in vitro and in vivo. This medicinal property has so far been reported in the leaves of this plant but not from other species of Mitragyna.

The excess stain was then drained onto absorbent paper and the slides were transferred into basic solution dye (methylene blue in phosphate buffer) for another 5 seconds. Finally the slides were rinsed briefly in the buffered water (pH 7. The slides were mounted with DPX and microscopic examination was then carried out similarly as described for WrightGiemsa staining procedure. AAD double staining for Kratom No More Euphoria Egypt apoptosis detection In principle the cell membrane of live cells is covered by phospholipids (lipid bilayer) in which phosphatidylserine is located on the inner layer of the plasma membrane.
MSE treated SH-SY5Y cells was not established in my preliminary experiments further assays were carried out to confirm this finding. The inhibitors used were caspase 3 inhibitor caspase 8 inhibitor caspase 9 inhibitor general caspase inhibitor negative control and doxorubicin as a positive control ( as described in section 5. The positive control doxorubicin confirmed the assay works by showing a highly significant response for apoptosis.
This phenomenon creates disadvantages for this assay as when the whole FACS profile shifts to the right side of the scale the determination of the stages of cell death is difficult to interpret as the cells are no longer located in specific quadrants. This observation is clearly in contrast with the previous cytological examinations which indicated that SH-SY5Y cells treated with high dose of MSE undergo apoptosis rather than necrosis. The right shifting phenomenon for MIT treated cells observed in fig. For HEK 293 and MCL-5 cells the effects seen were in agreement with the cytological examinations.

The cells were then ready to be used for the assay. The kratom dosage maeng da chemicals used in the assays unless indicated in the text were obtained from Invitrogen Company (U. K) and Sigma-Aldrich Company Kratom No More Euphoria Egypt (U.

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. 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. Therefore the possible involvement of the caspase enzymes such as upstream caspases 8 and 9 which are involved in both intrinsic and extrinsic pathways and also the executioner caspases 3 and 7 were investigated. Kratom No More Euphoria Egypt MSE mediated cell death was found to not involve any of the caspase cascades examined. Thus this finding is consistent with the previous data which indicates that the apoptotic-like cell death seen for MSE treated SH-SY5Y cells is p53independent and caspase independent.
