Although to date there is no report of cancer associated with consuming the leaves of this plant a 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. Kratom Borneo Maeng Da Oshkosh this finding again strongly supported the suggestion that MSE toxicity requires metabolic activation.
SH-SY5Y cells (105 cells per well) were seeded in 6 well plates and treated with various

concentrations of MSE and MIT for what is kratom made from the designated time period. Cells were harvested by routine trypsinisation procedure as described in chapter 2 (section 2. After the centrifugation process the supernatant was aspirated and the cell pellet was washed with PBS followed by centrifugation (1000 r.
M) MIT apparently stimulated cell proliferation that persisted up to 96 hr (Fig. This stimulation was small but consistent at 48 h to 96 hr. At higher doses of MIT buy kratom online usa (3.
Whether the MSE or MIT could possibly induce the same mechanism requires further investigations. As cell cycle arrest was noted further assessment using best head shop kratom immunoblotting was carried out using SH-SY5Y cells to determine the expression of p53 which is known to play a central role in cell cycle kratom induced anxiety larkspur arrest. Another fascinating finding noted was
that p53 protein was found to be lost in a dose-dependant manner with MSE treatment and to a lesser extent in the MIT treated cells.

The cells were then ready to be used for the assay. The chemicals used in the assays unless indicated in the text were obtained from Invitrogen Company (U. K) and Sigma-Aldrich Company (U. The Arochlor 1254-induced rat liver S9 was a kind gift from Dr.
This inhibition of proliferation persisted up to 72 hr (the duration of the study). Using pure compound MIT induced a differential response with maeng da kratom resin the HEK 293 cells. At very low doses (3.
