Abstract:

Ginsenoside Rc (Rc) is a major ginsenoside isolated from Panax ginseng, and has exhibited pharmacological effects on skin cells. The present study aimed to investigate the putative skin‑protective properties of Rc, including its anti‑photoaging and barrier function‑protective effects, in human HaCaT keratinocytes exposed to UVB radiation. The protective properties of Rc were evaluated through the assessment of keratinocyte viability, reactive oxygen species (ROS) production, total glutathione (GSH) and superoxide dismutase (SOD) activity, caspase‑14, matrix metalloproteinase (MMP)‑2 and ‑9 activity, and MMP‑2, MMP‑9 and filament aggregating protein (filaggrin) expression following UVB irradiation. Treatment with Rc was revealed to prevent the UVB‑induced increase in ROS production and pro‑MMP‑2 and ‑9 levels in HaCaT keratinocytes. In addition, treatment with Rc resulted in enriched GSH contents and enhanced SOD activity following exposure to UVB radiation. Furthermore, Rc treatment enhanced caspase‑14 activity and counteracted the UVB‑induced downregulation in filaggrin expression. However, no significant difference was identified between Rc‑treated and normal groups in terms of keratinocyte viability, regardless of exposure to radiation. The present findings suggested that Rc may exert anti‑photoaging and barrier function‑protective effects in keratinocytes, and thus protect the skin against photooxidative stress induced by exposure to UV radiation.
