Discovery of a family of cysteine protesases named caspases (Srinivasula et al 2001; Alnemri et al 1996) in mammalian cells has made important discoveries towards its function in cell death mainly in apoptosis. Their characteristic ability is to perform proteolytic cleavage at defined aspartate acid residues in various cellular substrates (Srinivasula et al 2001). Therefore the inference that MSE and MIT induced apoptosis which was kratom health effects suggested by cytological examination was further determined using caspases activation pathway. Kratom Powder Dosage Kodak in the first instance an assay was performed to look for possible activation of caspases 8 and 9 which are the main initiators in activating another caspases. 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.

This is consistent with the immmunoblot finding which indicates that p53 and p21 proteins were marginally expressed even at high doses of MIT. These findings indicate that MIT treated SH-SY5Y cells may execute cell death via an apoptosis pathway. If time had permitted more detailed examination of the involvement of caspases and other apoptosis-related proteins in MIT treated cells would have been desirable.

For cytotoxicity assay; MSE treated HepG2 cells were cultured as described in section 2. C for 10 min. The reaction was terminated with stop solutions provided with the kit. The plate was read using a fluorescent plate reader with an excitation wavelength of 560 nm and emission wavelength of 590 nm. Culture medium background) The total number of cells in each assay well was assessed using the proliferation assay protocol.
MSE in this cell line revealed that cell cycle arrest was again noted at 24 hr and more prominent at G1 phase. Again on reflection inclusion of control group for each time points would have aided Kratom Powder Dosage Kodak interpretation of these experiments. Based on the results of the three different cell lines examined it is suggested buy kratom herbal that MSE causes cell cycle arrest at G1 phase and S phase.
M for MSE and MIT respectively (Chapter 2). The nature of cell death observed was unknown and to the best of my knowledge there are no reports or information available on Mitragyna speciosa Korth toxicity on mammalian cells. In this study therefore an attempt was made to characterise the MSE and MIT toxicity by looking at cell cycle distribution. Firstly attempt was made to look at the cell cycle distribution in different cell lines using flow cytometry approach. Propidium Iodide is one of the most common and recommended dyes to use to quantitatively assess DNA content by flow cytometry (Darzynkiewicz et al 2001).
