Effects of almond skin extract (AE) and CHL on SIR2 (a), SOD1 (b) and SOD2 (c) gene expression determined by RT-qPCR. Expression was normalized with TUB1 gene and expressed relative to young yeast cells (Y). Y CTL was young yeast (on day 2 of cultivation) and A CTL was aged yeast (on day 5 of cultivation). AE, almond extract (1 mg/mL). CHL: chlorogenic acid at 3 concentrations (CHL5, CHL10 and CHL25 corresponding to chlorogenic acid addition at 5, 10 and 25 µM, respectively). E-Resveratrol (RES, 10 µM) was used as control antiaging drug. Values are means ± standard deviations (SD) of 4 independent experiments. Different letters represent significant differences between the various extraction conditions (p < 0.05).
