Effects of PLG on chemokine production in TNF-α/IFN-γ-induced HaCaT cells. a The cytotoxicity of PLG was determined by MTT assay. b–d Expression of RNATES, TARC, and MDC was analyzed with real-time RT-PCR. e–i Production of RNATES, TARC, MDC, MCP-1, and MIP-3α was examined by ELISA. Data represent the mean ± SEM of three independent experiments. ^#P < 0.05 ^##P < 0.01 and ^###P < 0.001 vs. Normal group; ^*P < 0.05, ^**P < 0.01 and ^***P < 0.001 vs. Control group
