Lentinuls edodes has been used for traditional food and medicine around Asia, and a variety of biological effects have been reported. In this study, L. edodes water extract (LWE) was investigated for its anti-photodamage effect in HaCaT keratinocytes. To perform the necessary assays, L. edodes was extracted with distilled water for 8 hr at 40℃ in an extract tank. Anti-photodamage activity was assessed using a scratch wound healing assay, cell proliferation, and a reactive oxygen species (ROS) scavenging test and by measuring the mRNA and protein expression levels of matrix metalloproteinases (MMPs) and type I procollagen. MMPs and collagen expression are major markers of UV-induced photodamage in skin. Prior to photodamage analysis, the total polyphenol and β-glucan contents of the LWE were evaluated and found to be 4.64 mg GAE/g DW and 165.96 mg/g, respectively. Treatment with LWE induced cell migration and cell proliferation in UV-irradiated HaCaT cells, and LWE effectively scavenged the ROS induced by H2O2 and UVB irradiation in HaCaT cells. UVB irradiation induced ROS generation and led to increased production of MMP-1 and MMP-9 and to decreased collagen production in human keratinocytes. Treatment with LWE upregulated the expression levels of MMP-1, MMP-9, and type I procollagen in UVB-irradiated HaCaT cells. This study suggests that LWE could be used to develop cosmetic materials with anti-photodamage effects.
