The cells stained with PI were analysed using BD FacsCalibur flow cytometer. PI was excited at 488 nm and 620 nm emissions. Ten thousand Kratom 50x Effects Richview cells were analysed by CellQuest Pro software and the subG1 population representing apoptotic cells were gated manually. Kratom 50x Effects kratom opiate like high venus Richview reactive oxygen species (ROS) analysis in SH-SY5Y cells treated with MSE and MIT ROS generation assay was carried out using SH-SY5Y cells by using a fluorescent dye 27-dichlorofluorescein diacetate (DCFH-DA). Principally this dye diffuses through the cell membrane and is hydrolysed enzymatically by intracellular esterases to form monofluorescent dichlorofluorescein (DCFH) in the presence of ROS.

PI and analysed with BD FacsCalibur flow cytometer in the Centre for Molecular Microbiology and Infection (CMMI) core facility unit Flowers Building South Kensington Campus. The procedures were as described in section 4 –
- As anticipated the experiments clearly showed that p53 was still being expressed in MIT treated groups and in control group but down regulated with time- dependant manner
- Values of each phase of the cell cycle were the mean of the three experiments with SEM
- Most sources say that it is a stimulant in lower doses becoming sedative in higher doses
- The next step was investigating the possibility of involvement of executioner caspases such as caspase 3 and 7
. Human embryo kidney- HEK 293 cells Using HEK 293 cells the effects of various concentration of MSE on the cell cycle profile was Kratom 50x Effects Richview determined at 24 and 48 hr time period (Fig. The 10000 events were collected during the acquisition and the phases of the cell cycle were gated manually using CellQuest Pro software.
In this chapter further investigation was attempted to explain these observations and to examine the mode of cell death of the cells treated with MSE and MIT. In general the two distinct pathways of cell death are via apoptosis or necrosis which are distinguishable morphologically and biochemically (Majno and Joris 1995; Wyllie et al 1980). The term of apoptosis was first coined by Kerr et al (1972) and it was described as an active way of killing the cells and organising its disposal which was easily detected under a microscope as cells undergo condensation of nuclear chromatin followed by formation of blebbing and segregation of the nucleus into fragments known as apoptotic bodies and finally disposed of by digestion via lysosomal pathway (Kerr et al 1972). Whereas necrosis described as a passive way of cell death is morphologically marked by cellular swelling chromatin condensation followed by cellular and nuclear lysis with subsequent inflammation (Wyllie et al 1980).

Under normal circumstances the four phases of the cell cycle G1 S G2 and M phases are tightly regulated. The entry of the cell into each phase of cell cycle is carefully regulated by cell cycle checkpoints which act as the cell cycle control systems. The cell cycle control system has been identified as a series of proteins (e. Cdks) that work together to activate the different phases of cell cycle (Morgan 2008; Alberts et al 2002). M and metaphase-anaphase transition (Murray and Hunt 1993) and these checkpoints maintain cell cycle arrest which gives time for damaged cells to be repaired and then to continue proliferating.
