Fig. 2From: A standardized extract of Asparagus officinalis stem prevents reduction in heat shock protein 70 expression in ultraviolet-B-irradiated normal human dermal fibroblasts: an in vitro studyEffect of EAS pretreatment on the UV-B irradiation-induced reduction in HSP70 protein levels in NHDFs. The cells were treated with EAS or dextrin for 24 h; immediately after UV-B irradiation, the cells were further cultured in supplemented medium for 6 h. The relative ratios of HSP70 with respect to GAPDH are shown. Mean ± SEM (n = 3). *p < 0.05; **p < 0.01 (one-way ANOVA and Tukey’s test)Back to article page
