B12 is particularly important for us humans as it plays an essential role in the formation of red blood cells, which carry oxygen around the body
The difference between the effects of both QIs on the cell viability ( Figure 2 ) and caspase 3 activation ( Figure 4 ) suggests that upon GSH depletion, the decrease in cell viability is not only apoptosis dependent but also most likely depends other cell death pathways, such as necrosis ( IC 50 values of QIs under GSH-depleted conditions were around 20 M ( Figure 2 ), which is higher than the plasma concentrations of AQ and DEAQ found in patients, normally in nanomolar to micromolar ranges ( in vivo may be lower, exposure continues for a prolonged period as the half-life of DEAQ is 10 to 12 days ( The relative contribution of GSTP1 to GSH-conjugation of both QIs was highest at GSH-depleted conditions, while in absolute quantities a higher GSTP1-dependent increase of GSH conjugate formation was seen without BSO pre-treatment ( Figure 5 )
It has been reported that the incubation of HepG2 cells for 24 h with 60 M QE resulted in numerous cells that had smaller nuclei with chromatin condensation and perinuclear apoptotic bodies
