Curcuma aromatica and Curcuma comosa extracts and isolated constituents provide protection against UVB-induced damage and attenuate matrix metalloproteinase-1 expression in HaCaT cells.

บทคัดย่อ ( Abstract )

Ultraviolet-B (UVB) exposure is one of the primary extrinsic factors causing skin photoaging. It stimulates inflammatory responses and arrests the cell cycle. Matrix metalloproteinase-1 (MMP-1) secreted by keratinocytes is one of the important extracellular matrixes to attenuate UVB-induced skin aging via collagen degradation. Curcuma aromatica (CA) and Curcuma comosa (CC), the herbaceous plants in the Zingiberaceae family, are commonly used in Thai traditional women’s medicines. The present work was aimed to investigate the potential of the CA and CC extracts and their isolated compounds to attenuate UVB-induced MMP-1 and cell cycle arrest in HaCaT keratinocytes. Total phenolic contents and antioxidant capacities of the extracts were determined. CC extract contains more phenolic components and provides more potent antioxidant activities than CA extract. HaCaTs were pretreated with the extracts or their isolated constituents 1–4 for 24 h and then repeatedly exposed to UVB at 100 mJ/cm2 10 times. Both extracts and compounds 1–4 effectively reduce UVB-induced MMP-1 levels in HaCaT cells and restore cell cycle arrest. This is the first report on the potential of CA and CC extracts in reducing UVB-induced MMP-1 expression and regulating cell proliferation in HaCaT cells. Thus, CA and CC extracts might be used as alternative natural agents to prevent UVB-induced skin photoaging.
