Evaluation and enzyme-aided enhancement of anti-photoaging properties of Camellia japonica in UVA-irradiated keratinocytes.
Exposure to ultraviolet (UV) radiation is the main reason behind extrinsic skin aging. Changes due to chronic UV exposure are called photoaging. Natural products are effective ingredients against UV-mediated skin damage. Present study investigated the anti-photoaging properties of Camellia japonica flowers which possess various bioactivities. To enrich the extracts of C. japonica flowers, pectinase and beta-glucosidase treatment was employed. Anti-photoaging effect was screened using the changes in MMP-1 and collagen levels in UVA-irradiated human HaCaT keratinocytes. The crude extract of C. japonica flowers (CE) was shown to decrease the UVA-induced MMP-1 secretion while attenuating the collagen levels. Pectinase and beta-glucosidase treated CE (ECE) showed increased anti-photoaging effects against UVA-induced changes in MMP-1 and collagen production. Camellenodiol (CMD), a known triterpenoid from C. japonica, isolated as the active ingredient of ECE and its anti-photoaging effect was screened. Results showed that CMD ameliorated the UVA-induced deterioration in collagen levels by suppressing MMP-1 production in transcriptional level. CMD treatment downregulated the phosphorylation of p38, ERK, and JNK MAPKs along their downstream effectors, c-Fos, and c-Jun. In conclusion, enzyme-assisted extraction of C. japonica flowers was suggested to enhance the anti-photoaging properties suggestively through high bioactive content such as CMD.
期刊介绍:
A Journal of Biosciences: Zeitschrift für Naturforschung C (ZNC) is an international scientific journal and a community resource for the emerging field of natural and natural-like products. The journal publishes original research on the isolation (including structure elucidation), bio-chemical synthesis and bioactivities of natural products, their biochemistry, pharmacology, biotechnology, and their biological activity and innovative developed computational methods for predicting the structure and/or function of natural products. A Journal of Biosciences: Zeitschrift für Naturforschung C (ZNC) welcomes research papers in fields on the chemistry-biology boundary which address scientific ideas and approaches to generate and understand natural compounds on a molecular level and/or use them to stimulate and manipulate biological processes.
