Kratom is in the same family as the coffee tree (Rubiaceae). Kratom Resin Reviews our Kratom is freshly imported Indonesia and is of the highest currently known commercial grade. The genus Mitragyna belongs to the family Rubiaceae and is found in swampy territory in the tropical and sub-tropical regions of Africa and Asia.

In this Kratom Resin Reviews study SH-SY5Y cell death induced by MSE appeared to be independent of p53 and p21 pathway. However the morphological features indicated apoptoticlike type of cell death. Based on these findings it was postulated that the mechanism of cell death of SH-SY5Y cells upon MSE treatment may not follow the common intrinsic pathway which requires the activation of tumour suppressor protein p53.

The fluorometric readings
with SH-SY5Y cells which were treated with high doses of MSE as early as 4 hr failed to show any significant caspase 8 and 9 activities. 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.
S9 that contribute to activating MSE toxicity. Arochlor 1254 is known to be a potent inducer of wide range of mixed-function oxidase enzymes (Puga and Wallace 1998; Ryan et al 1977). CYP 2E1 may have a role in activating MSE toxicity.
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.

C prior reading the absorbance at 405 nm using plate reader. Then the cells were treated with MSE and MIT for 4 hr and 18 hr incubation time points. After each incubation time point the cells were harvested by trypsinisation and centrifugation as described in chapter 2 section 2.
H202 significantly released ROS as soon as it was added to the cells (at the 30 minute time interval) and mitragyna speciosa combinations was consistently higher than other group treatments. The incubation of anti-oxidant NAC 30 minutes prior to adding H202 appears to reduce Kratom Resin Reviews the ROS production. Interestingly both high doses of MSE and MIT appeared similar to control groups and indicate that there was no ROS generation in this cell line. Another important microscopic observation was made after the final readings at the 1 hr time point which showed that all cells in the Control group appeared rounded and floating in the middle of the well.
