Anti-Aging Effects of Gyrophoric Acid on UVA-Irradiated Normal Human Dermal Fibroblasts

Abstract

This research was conducted to identify the anti-aging effects of gyrophoric acid on the skin, using normal human dermal fibroblasts. The anti-aging effects of gyrophoric acid on dermal fibroblasts were demonstrated through cell viability, verification of collagen, type I, alpha 1 (COL1A1)/COL3A1/matrix metalloproteinases 1 (MMP1) messenger ribonucleic acid (mRNA) expression levels with quantitative real-time reverse-transcription polymerase chain reaction, and protein estimation using type I collagen/MMP1-enzyme-linked immunosorbent assay. Further, the effects of gyrophoric acid on superoxide dismutases (SODs)/catalase were investigated by assessing their mRNA expression. In ultraviolet A (UVA)-treated dermal fibroblasts, gyrophoric acid was observed to increase mRNA levels of COL1A1/COL3A1/SOD2 genes and type I collagen protein levels, consistent with its anti-aging role. Furthermore, gyrophoric acid treatment decreased both MMP1 mRNA and protein expression levels. Therefore, the results of this study demonstrate that gyrophoric acid can be considered as an important natural compound with potent anti-aging effects on the skin. Based on the findings of this study, further research about the mechanism of action of gyrophoric acid should be pursued so as to develop novel anti-aging strategies not only in the field of cosmetics but also for healthcare.
