| Abstract |
The cryoprotective effect of intracellular free high-mannose oligosaccharides (HMOS) on mammalian cells and proteins was examined by monitoring PC-12 cell viability and assaying protein kinase C (PKC)-epsilon activity. 1-Deoxymannojirimycin, an inhibitor of alpha-mannosidase, to cause an increase in intracellular free HMOS, significantly rescued PC-12 cells with 2-h freezing insult at -15 degrees C in a concentration (1-50mM)- and pretreatment time (48-72h)-dependent manner, as compared with unpretreated cells; full rescue from freezing injury was obtained with 1-deoxymannojirimycin at more than 25mM for 48-h pretreatment and more than 3mM for 72- and 96-h pretreatment. For PC-12 cells pretreated with 1-deoxymannojirimycin at 1mM for 72h, thawed cell viability after more than 8-w cryopreservation at -80 degrees C in 10% (v/v) dimethyl sulfoxide was much higher than that for cells without pretreatment. PKC-epsilon activity was well preserved after 16-h cryopreservation at -20 degrees C in the presence of mannose 9-N-acetylglucosamine 2 (Man9-GlcNAc2) (1 mM), an HMOS, while the activity was reduced to 15% without Man9-GlcNAc2. Collectively, the results of the present study suggest that intracellular free HMOS is a key molecule to protect mammalian cells and proteins from freezing injury; in other words, HMOS could be a new target for cryopreservation of mammalian cells and proteins.
