The effect of the 50% EtOH extract and EtOAc fraction of coffee silverskin on UVB-induced MMP-1 expression. Cell viability determined using the MTT assay (a). The levels of UVB-induced MMP-1 expression in HaCaT cells were measured by ELISA (b) and western blot analysis (c). Data are presented as the mean ± S.D. values. *p < 0.05 compared with the UVB-irradiated control, #p < 0.05 compared with the unirradiated control. β-actin was used as an internal control
