Route of Administration: Topical
When normal human dermal fibroblasts were irradiated with UVA after a pre-treatment with 10 uM of Zinc Pidolate (Zinc PCA) for 16 h, this pretreatment suppressed the UVA-induced c-Fos expression to 110%, in comparison with the value of 200% obtained without such Zinc PCA pre-treatment. Zinc PCA induced SVCT2 mRNA expression in NHDFs in a dose-dependent manner, i.e., 115% at 25 uM and 125% at 50 uM, in comparison with the control.
