Therefore to further determine whether p21 is positively linked with p53 in response to MSE or MIT we examined p21 levels using immunoblots. The quantitation of p21 protein is described in section 4. There was a clear up regulation of p21 protein seen for the control group at 24 and 48 hours consistent with the upregulation of p53 noted earlier. Kratom Black Label Pills Lignum mSE at any time point. This finding supports the previous p53 results. Parallel experiments were carried out to assess the effects of MIT on the expression of p21 protein.
MCL-5 cells With the metabolically competent MCL-5 cells kratom dosage opiate like effects there was a pronounced dosedependent inhibition of cell proliferation at all concentrations of MSE within 24 hr (Fig. By 48 hr proliferation of cells treated with the lowest concentration of MSE (1. As with the HepG2 cells MSE associated cell death was only apparent at doses Kratom Black Label Pills Lignum higher than 11. The IC50 for this cell at 24 hr period is 410. MSE (Table 2.

Propidium Iodide is one of the most
common and recommended dyes to use to quantitatively assess DNA content by flow cytometry (Darzynkiewicz et al 2001). The dose response and temporal effects of treatment were examined in this assay in order to maximally evaluate the effect on the cell cycle. Cell cycle analysis was initially performed using HEK 293 cells and the DNA profile was determined manually using the Cellquest Pro software (Fig.

It is proposed that despite taking up the trypan blue dye the cells were still alive but may not be fully functional. It is speculated that one effect of the MSE treatment could be opening of membrane pores to allow the dyes mitragyna speciosa – premium kratom leaf to get in without proceeding to cell death. However at higher dose of MSE dye uptake is more likely to represent cell death. The 1H-NMR analysis of MSE and MIT from two different sources revealed the similarity of most spectral peaks for both samples of MIT except there is an extra minor peak at 7. MIT from Japan. This contamination was not seen in the MIT from Malaysia.
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.
Naloxone ANOVA with Bonferroni post test. Cyprodime hydrobromide (C). Nt ANOVA with Bonferroni post test. The nature of cell death and mechanism associated with it is yet to be reported. Thus in this part of this thesis several investigations were attempted to provide possible mechanism of the nature and mode of cell death seen with a selected panel of human cell lines. The cytological examination using three different cell lines (SH-SY5Y HEK 293 and MCL-5 cells) was the first investigation.
C prior reading the absorbance at 405 nm using plate reader. Then the cells were treated with MSE and MIT for 4 hr and 18 hr incubation time points. After each incubation time point the cells were harvested by trypsinisation and centrifugation as described in chapter 2 section 2. This assay was performed as instructed by the manufacturer Promega USA. Serial fluorescence readings were performed using a plate reader at 485 nm excitation and 520 nm emission.

However on the longer term effects of treatment (clonogenicity assay) as shown in fig. M kratom 15x bluelight naloxone was found not sufficient to inhibit the MSE toxicity at the same concentration used for previous experiments. M did give a positive response.
