These cleave regulatory and structural molecules to execute the cell death programme (Ghobrial et al 2005). Extrinsic pathway The extrinsic pathway or death receptor pathway triggers apoptosis via various pro-apoptotic protein receptors located on the plasma membrane of the cells (Fulda and Debatin 2006) which mainly belong to the tumour necrosis factor (TNF) receptor superfamily (Zapata et al 2001). These proteins include death receptors the membrane bound Fas ligand (FasL) the Fas complexes and the Fas associated death domain (FADD) and also the initiator caspase 8 and 10 (Ghobrial et al 2005).

study provided information that MSE itself is not able to promote cellular migration in vitro. The results from different cell lines used in the viability studies demonstrated that the human neuronal SH-SY5Y cell was the most sensitive cell Kratom Reviews 2013 line examined.

HEK 293 cells treated with MSE and Arochlor 1254-induced rat liver S9 (Fig. B) appeared to be more resistant to the toxicity effects compared to SHSY5Y cells (Fig. These results indicate that MSE is being activated to a metabolic product that is cytotoxic to both cell lines; however the SH-SY5Y cells appear to be most susceptible.
Salmonella typhimurium (Ames et al 1972). Principally this test employed bacterial strains of S. Therefore only bacteria mutated to histidine independence may continue to grow and form colonies.
This stimulation was small but consistent at 48 hr to 96 hr. At higher doses of MIT (3. M) cell proliferation was inhibited (Fig. These concentrations also induced substantial cell death (Fig. The IC50 of these cells at 24 hours treatment are estimated as 282.
In addition currently nothing is known on any involvement of mammalian metabolism in MSE and MIT associated toxicity. Therefore to examine this objective both metabolically competent and non-competent cell lines and also rat liver post mitochondrial supernatant (S9) have been used to examine the potential role of metabolism in toxicity. MSE was the main agent used in this study. It has been proposed that MSE extracted using modification of Houghton and Ikram method (1986) contains more MIT than any other reported crude extraction processes (Baharuldin 2000).
These results indicate that MSE is being activated to a metabolic product that is cytotoxic to both cell lines; however the SH-SY5Y cells appear to be most susceptible.

The cells which have lysed plasma membrane such as in late apoptosis are permeable to dye (Puranam and Boustany 1998). FITC (fluorescein isothiocyanate) or PI (Vermes et al 1995) or 7-AAD (7Amino-actinomycin D) (Schmid et al 1992). Other in vitro cytotoxicity assays which assess the biochemical activity of damaged cells include lactate dehydrogenase assay (LDH) which in principle measures the release of lactate dehydrogenase enzyme during pathological states such as cell
