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). kratom and opiate high 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. The effect of several concentrations of MSE was compared at two times 24 and 48 hr. MSE with concomitant increased subG1 population especially after 48 hr treatment. The subG1 phase is proposed to be an apoptotic population (Darzynkiewicz et al 1992) as cells with condensed DNA appeared to stain less with PI and will appear to the left of the G1 peak.
This finding suggests that the mode of the cell death of MIT treated cells is dependant on caspase 3 and 7 activation pathway. There were no significant differences in the subG1 population (apoptosis population) between treated groups (caspase 3 kratom capsules what do they do inhibitor caspase 8 inhibitor caspase 9 inhibitor and general caspase inhibitor treated with high dose of MSE) and the control and negative control groups. At this stage it seems that despite having high MIT content in Kratom Legal Military Scottsville the MSE the high dose MSE treatment in SH-SY5Y cells does not activate caspase enzymes.

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 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. Although to date there is no report of cancer associated buy kratom seeds australia chesnee with consuming the leaves of this plant genotoxic assessment such as mutagenicity aids prediction of carcinogenicity potential. Thus for the first time I have shown that genotoxicity testing using the mouse lymphoma tk gene mutation assay (MLA) suggests that MSE and MIT have no genotoxic potential. This MSE toxicity was similar to that noted for MSE with the human cell lines (SH-SY5Y and HEK 293 cells) in the presence of S9.
M where there was evidence for a G1 arrest. The
observations on the right shifting of the DNA profiles which was pronounced in the high doses of MSE and MIT in MCL-5 and SH-SY5Y cells has raised question in this study. This phenomenon implies that the live cells have taken up more PI thus increasing the DNA staining intensity. At this stage the possible explanation for this phenomenon is unknown however; it could be due to the plasma membrane integrity being compromised due the treatment effects thus creating pores or increase membrane mitragyna speciosa effecten hartsburg permeabilisation. Numerous studies have shown that wild-type p53 can restrain cell cycle progression and kratom ban in indiana chilhowie induce cell death via apoptosis when the cell is irreversibly damage (Sugrue et al 1997).
