B also revealed a negative outcome for genotoxicity under conditions with or without the presence of metabolic activation by S9. In this case the metabolic activation by S9 did not activate the toxic effects of MIT which was contrary to what we had seen for MSE. The survival rate was reduced to 17% of the vehicle treated control and this was thought due to the low viability rate (18.

Take 50 grams of dried crushed kratom leaves and put them in a pot. Add 1 liter of water. Boil gently for 15-20 minutes. Put the leaves back in the pot and add another liter of fresh water.
Based on the kratom hangover treatment literature it was well known that p53 has the ability to induce G1 arrest and its target gene p21 facilitates the arrest (Ko and Prives 1996) by inhibiting the function of CDKs (Gu et al 1993; Harper et al 1993). Therefore the role of p53 and p21 in MSE and MIT induced toxicity were examined. However in the present studies the cell cycle arrest noted appeared to be independent of induction of p53 and p21. The loss of the protein was strongly dose-dependant as there was a time dependant induction of p53 expression observed in the control and lower dose groups indicating a normal p53 expression response in this cell line.

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.

Effects of MSE and MIT on p53 target gene product p21 It is well does kratom affect gaba berlin established that induction of p53 can lead to expression of target gene p21 and thereby cell cycle kratom powder how to prepare arrest.

Kratom is the common name for a plant that carries the scientific name: Mitragyna speciosa Korthals. The traditional use of this plant dates back many centuries and of course has its origins in Thailand. In recent times kratom has become popular for recreational purposes because of the pleasant effects the leaves of this plant can have.

The effect of MIT on the expression of p53 was also assessed. MIT has demonstrated weak toxicity effects compared to ME. As anticipated the experiments clearly showed that p53 was still being expressed in MIT treated groups and in control group but down regulated with time- dependant manner. M) the same pattern of p53 down regulations was seen as with the higher dose of MSE. The next experiment was carried out to further investigate if there was a correlation between p53 changes and its target gene p21 in response to MSE and MIT treatment. The control and low dose groups however did express p21 protein consistent with the p53 expression. In the parallel experiment with MIT again p21 was expressed in a time-dependant manner that correlated with p53 expression.
The subG1 phase has been proposed to be a population of apoptotic cells (Darzynkiewicz et al 1992). Effects of MSE on cell cycle distribution of HEK 293 cells after 24 and 48 hours of treatment.
