WAF 1 is a p53 target gene and both are buy kratom manhattan well known to have positive correlation with cell cycle arrest (Morgan 2007; Harper et al 1993). Based on the 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 Kratom Pills Bluelight Big Sur 1993). Therefore the role of p53 and p21 in MSE and MIT induced toxicity were examined. Kratom Pills Bluelight Big Sur however in the present studies the cell cycle arrest noted appeared to be independent of induction of p53 and p21.

Morphologically after MSE insult SH-SY5Y cells appeared to die via apoptosislike cell death whereas MCL-5 and HEK 293 cells show predominantly a necrotic type of cell death. Biochemical investigations confirmed that MSE induced SH-SY5Y cell death independent of p53 or caspases therefore the mechanism of apoptotic-like morphology features is not entirely clear however a few possible mechanisms for this type of cell death can be proposed. MIT induced cell death in SH-SY5Y cells appeared to be Kratom Pills Bluelight Big Sur associated with p53 and caspasesdependant pathway however lacking morphological examinations restricts the confirmation of this finding.
Further experiments were carried out to determine the
time course of the down regulation or loss of p53 (Fig. MSE and control groups implying that this cell line expresses p53 protein and the lost of p53 protein seen at high doses was due to treatment effects. kratom tea in the morning princeton juncti kratom powder or leaves Parallel immuno blotting experiments were also carried out Kratom Pills Bluelight Big Sur for MIT as shown in fig. There was no significant difference in the p53 levels noted over the dose range used however they appeared to be down regulated compared to the control group. The time course of MIT induced p53 change was also carried as shown in fig.
In the early stage of the testing ICH has recommended an approach called standard test battery which includes three core tests as below: i) a test for gene mutation in bacteria (the Ames Test). Chemicals giving positive results in the standard battery tests depending on their intended use Kratom Pills Bluelight Big Sur may need to be tested more extensively whereas negative results will usually provide a sufficient level of assurance of safety
(ICH 1997). Based on the ICH recommendation for staged genotoxicity assessment gene mutation in bacteria (the Ames test) was the appropriate first Kratom Pills Bluelight Big Sur test to be performed; however since the leaves of Mitragyna speciosa Korth have long been used by humans an in vitro test using mammalian cells was thought to be more relevant to perform in the current study.
