Abstract
BACKGROUND: UVB radiation triggers skin photoaging by inducing excess cellular oxidants, contributing to senescence, and overproducing matrix metalloproteinase-1 (MMP-1), causing skin wrinkles. Senescence also impedes skin wound closure. Passion fruit seeds (PFS) boast abundant piceatannol (PCT), recognized for its antioxidant and anti-aging properties. OBJECTIVE: To study potential of PFS extract in diminishing photoaging, accelerating wound healing, and enhancing SIRT1 production in human keratinocytes (HaCaT cells). METHODS: The PFS extract was assessed for PCT using HPLC analysis. The antioxidant effects, reduced senescence-associated β-galactosidase (SA-β-gal) activity, and MMP-1 production were measured in HaCaT cells exposed to UVB using a DCFA-DA assay, SA-β-gal activity, and flow cytometry/immunofluorescent including MMP-1 mRNA expression, respectively. The effect of wound healing acceleration was evaluated, including EGFR mRNA expression. Additionally, SIRT1 enhancement was investigated using flow cytometry and immunofluorescent techniques, which also included the assessment of SIRT1 mRNA expression. RESULTS: The PFS extract, which is rich in PCT, effectively diminished cellular oxidants and aging. It decreased UVB-induced cellular oxidants, senescence, and MMP-1 production at both protein and mRNA levels. Moreover, the extract enhanced wound closure by boosting cell migration and increasing EGFR mRNA expression. Additionally, SIRT1 production and expression, associated with cellular rejuvenation, increased in extract-treated cells. CONCLUSIONS: PFS extract exhibits potential for skincare and wound healing applications, offering a natural strategy to combat skin aging effects and support tissue repair.
