From: Protective effects of Camellia japonica flower extract against urban air pollutants
Anti-pollution effects of CJFE assessed by MMP-1 inhibition (a) and quantitative RT-PCR results of urban dust-induced MMP-1 expression in NHDFs (b). The results are mean ± standard deviation (SD) (n = 3). *P < 0.05, **P < 0.01 vs. pollutant-untreated control. #P < 0.05, ##P < 0.01 vs. pollutant-treated control
