Abstract:

Normal human skin fibroblast (NHSF) cells and HaCaT cells were applied to establish evaluation models of dehydration, light-aging and oxidative stress. Based on the models, the protective effects of Y2SK2 and SK3 type dehydrins from Agapanthus praecox (ApY2SK2 and ApSK3) on human skin cells were studied. The results showed that, the safe concentration of dehydrins was 0.01-10 μmol/L. Light-aging and oxidative stress could cause oxidative damage and apoptosis of human skin cells. 10 μmol/L ApSK3 could increase the activity of skin cells by 57%-91% after cryopreservation. ApSK3 could significantly improve the activity of skin cells under dehydration. Both the two dehydrins provided anti-oxidative protection for skin cells in the models of light-aging and oxidative stress, in which the level of malondialdehyde was decreased by 10%-36% and the activity of SOD was significantly increased for HaCaT cells. The activity of casepase-3 and casepase-8 was decreased by ApSK3 according to the oxidative stress model, and the occurrence of programmed cell death was reduced. The research showed that, Y2SK2 and SK3 type dehydrins from Agapanthus praecox could protect human skin cells against stress damage, the mechanism of which could possibly be related to the enhanced cell anti-oxidation and their participation in the process of cell apoptosis.

Key words: dehydrin, HaCaT cell, NHSF cell, oxidative stress, cell apoptosis
