Use your common sense. Kratom Shop Europe pregnant or breast-feeding women and children under 18 should not take any drug or medicationexcept on medical advice. We strongly advise that any woman who could possibly be pregnant NOT use kratom.
The loss of p53 protein was noted as early as 6 hr after MSE treatment. A similar finding was also observed for p21 protein. P21 is one of the main target genes for p53 and both p53 and p21 are well known to have a positive correlation in assisting the cycle arrest by inhibiting the cyclinCdks complex formation (Morgan 2007).
Prior to this study MIT was thought to be the compound responsible for the narcotic effects of this plant. In the early part of this study basic in vitro toxicology revealed

that MSE and MIT have dose dependant toxicity to several human cell lines and the SH-SY5Y cell was the most sensitive. This is not surprising as the central nervous system was pharmacologically determined as the target system for the biological effects of this plant thus a toxicity response might be anticipated in neuronal cells.

Such events are more common in mammalian cell mutagenesis (Clive et al 1990). Mitchell et al 1997). In general MSE with or without the presence of metabolic activation (Arochlor 1254 induced rat liver S9) was negative for genotoxic potential. MSE in the presence of S9 turned out to be positive. RTG and also low RSG (24%) prior plating.
A second incubation time point at 18 hr also showed negative results. The next step was investigating the possibility of involvement of executioner caspases such as caspase 3 and 7. The executioner caspases are also known as downstream caspases as they depend on active initiator caspases for their activation by proteolytic cleavage (Srinivasula et al 2001). As anticipated there was no activation of caspases 3 and 7 activities in cells treated with high dose of MSE at both 4 hr and 18 hr incubation time points. Interestingly for MIT there was a clear significant difference of caspases 3 and 7 activities at both concentrations of MIT tested. This finding suggests that the kratom caps review charlotte 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 inhibitor caspase 8 inhibitor caspase 9 inhibitor and general caspase inhibitor treated with high dose of MSE) and the control and negative control groups.
