The basic toxicology data established in the previous chapter has informed us on the potential cytotoxicity of MSE and MIT on several human cell lines which generally shows cytotoxicity with high dose. The lethal effect of the extract and major alkaloid (MIT) on the cells examined prompted the question whether cell death was accompanied by DNA damage. DNA damage as a result of endogenous sources (cellular metabolic processes) or exogenous sources (environmental factors such as chemical insult) could lead to reversible or irreversible genetic change. Based on the long term use of this plant by humans testing for its genotoxic potential using mammalian cells was thought to be more appropriate than conventional first tier testing for gene mutation in bacteria. In fact the primary first tier bacterial genetic toxicology assay the Ames Salmonella assay is incapable of detecting large scale deletion or recombination events of the mutations.

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; Uei Kratom For Opiate Withdrawal it could be due to the plasma membrane integrity being compromised due the treatment effects thus creating pores or increase membrane permeabilisation. Numerous studies have shown that wild-type p53 can restrain cell cycle progression and induce cell death via apoptosis when the cell is irreversibly damage (Sugrue et al Uei Kratom For Opiate Withdrawal 1997). WAF 1 is a p53 target gene and both are well known to have positive correlation with cell cycle arrest (Morgan 2007; Harper et al 1993).

M MIT indicating the loss of p53 protein over time. The findings described above suggest that the cell cycle arrest of MSE treated cells seen previously with flow cytometry was independent of p53 protein induction and to the lesser extent for MIT treated cells. P53 levels of MSE treated SH-SY5Y cells after 24 hr treatment. Bars are the mean of three experiments with SEM. P53 levels of MSE treated SH-SY5Y cells at different time points (6 12 24 and 48 hr). P53 levels of MIT treated SH-SY5Y cells after 24 hr treatment.
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.
