Fig. 2From: Cudrania tricuspidata leaf extracts and its components, chlorogenic acid, kaempferol, and quercetin, increase claudin 1 expression in human keratinocytes, enhancing intercellular tight junction capacityExpression of tight junction-related genes. a HaCaT cells were treated with different concentrations of WECT for 24 h. Only claudin 1 mRNA was increased, in a dose-dependent manner. **p < 0.01, ***p < 0.001 (two-sided t-test, versus control) b Upon treatment with EECT, there were no significant changes in expression of tight junction-related genesBack to article page
