In determining the mechanism of cell death induced by MSE and MIT it was noted that MSE caused a different mode of cell death depending on cell type. 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. Get Kratom Voucher mIT induced cell death in SH-SY5Y cells appeared to be associated with p53 and caspasesdependant pathway however lacking morphological examinations restricts the confirmation of this finding. The study also confirmed that there was no involvement of ROS production in MSE and MIT induced cell death implying Get Kratom Voucher
that mitochondrial integrity is not compromised.
Cell viability was assessed as routine Trypan blue exclusion procedure described in section 2. Analysis of MSE using UV-VIS spectrometer A UV-VIS spectrometer (WPA Lightwave II) was utilised for estimating the MIT content in the MSE fraction samples by measuring UV spectral characteristics of MIT. Using pure MIT referral compound the UV spectrum exhibited a maximum absorbance at 227 nm. A standard curve for MIT was generated (Fig. The absorbance reading for each MSE fraction at 227 nm wavelength was recorded. Using the equation derived from the MIT standard curve an estimation of MIT present in each MSE fraction was calculated (refer to Appendix 1 for details of best place to order kratom online calculations).

Culture medium background) The total number of cells in each assay well was assessed using the proliferation assay green riau kratom review protocol. In order to estimate the percentage of dead cells after treatment with MSE or MIT cells were harvested by centrifugation and with trypsinisation for adherent cells. The cells were then stained with trypan blue Get Kratom Voucher solution (0.
The increase of subG1 population was also prominent at these two highest doses. DNA replication process occurring (increased S phase cells). This finding was found to be in contrast to the previous MCL-5 results (Fig. The control cells also show a similar DNA profile as the treated cells at the same time point.
MIT has a lesser effect and cells arrest mainly at G1 phase in SH-SY5Y cells. The cell arrest occurring at high doses of MIT was found to be correlated with p53 and Get Kratom Voucher p21
expression although the expression changes were marginal compared to control and lower dose groups. The mechanism Get Kratom Voucher for cell cycle arrest in the cells treated with high doses of MSE remains unclear as there was no correlation with p53 and p21 as both proteins were lost after the treatment.
