Beta-galactosidase expressions in HDFs. HDFs were treated for 24 h with 0.2 mg/ml aqueous extract of P. betle, 0.1 mg/ml hot water extract of C. vulgaris and 0.5 mg/ml TRF. Black, blue, red and green bars represent control, P. betle, C. vulgaris, and TRF treatments, respectively. ap < 0.05 compared to young HDFs, bp < 0.05 compared to pre-senescent HDFs, cp < 0.05 compared to P. betle-treated young HDFs, dp < 0.05 compared to P. betle-treated pre-senescent HDFs, ep < 0.05 compared to senescent HDFs, fp < 0.05 compared to C. vulgaris-treated young HDFs, gp < 0.05 compared to C. vulgaris-treated pre-senescent HDFs, hp < 0.05 compared to TRF-treated young HDFs, ip < 0.05 compared to TRF-treated senescent HDFs. Data are presented as mean ± SEM, n = 6.
