Therefore to further determine whether p21 is positively linked with p53 in response to MSE or MIT we examined p21 levels using immunoblots. The quantitation of p21 protein is described in section 4. There was a clear up regulation of p21 protein seen for the control group at 24 and 48 hours consistent with the upregulation of p53 noted earlier.
A similar phenomenon has been described in the literature with dynorphins endogenous opioid Kratom Tea Easy Prudence Island peptides which function as ligands for the kappa-opioid receptor and induce non-opioid excitotoxic effects. Kratom Tea Easy Prudence Island dynorphins mitragyna bridge city are believed to cause excitotoxic effects by inducing perturbations or pore formation on the lipid bilayer of plasma membrane (Hugonin et al 2006). Hugonin et al (2006) also mentioned in their work that the high positive charge of the compound contributed to the mechanism as it will bind with the negative charge of the Kratom Tea Easy Prudence Island glycosaminoglycan of plasma membrane and thus enhance the dynorphin activities. Whether the MSE or MIT could possibly induce the same mechanism requires mitragyna speciosa trees for sale wadena further investigations. As cell cycle arrest was noted further assessment using 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 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.
Human lymphoblastoid – MCL-5 cells For this cell line the cell cycle analysis was carried out using Cellquest Pro software and the aggregated cells (doublet cells) were gated out. The DNA profiles were determined using Modfit LT cell cycle analysis software (Verity Software Topsham ME). The effect of MSE for 24 and 48 hr time period (Fig. M phase cells was noted for all doses compared to control cells for the first 24 hr treatment period. However there were no apparent DNA profile changes seen for the 48 hr treatment group.
Cytological examination of SH-SY5Y cells after 48 hr treatment with MSE (24 hr treatment and 24 hr Kratom Tea Easy Prudence Island doubling time). Each photo is representative of 3 similar experiments with the same treament concentration stained with WrightGiemsa staining. Magnification (x 1000). Cytological examination of HEK-293 cells after 48 hr treatment with MSE (24 hr treatment and 24 hr doubling time). Each photo is representative of 3 similar experiment with the same treatment concentration stained with WrightGiemsa staining. Necrotic cells were noted based on the lysis of membrane appearance and swelling of cells with reduced staining intensity compared to control and low dose mitragyna rotundifolia la harpe groups.

Cells treated with both high concentrations of MSE (Fig. A) and cells pre-treated with NAC appeared similar to Control group. This infers that MSE did not generate ROS which confirmed the earlier finding. With MIT treatment groups (Fig. B) similar findings were clearly seen. NAC appeared no different compared difference between bali and thai kratom to Control group.
