Effect of salidroside (SAL) on the miR-22 expression in near-senescent human fibroblasts. (a) The miR22 expression was analyzed by miRNA microarray, presented as fold changes in the miRNA expression. (b) Relative quantitation of the miR-22 expression in 2BS fibroblasts at 30PD, 50PD, or 50PD cells treated with SAL at 10 μM for 48 h was analyzed by qRT-PCR analysis. miR-22 expression levels were indicated relative to those in 30PD set at 1. U6 was used as an internal normalization control. ∗∗P < 0.05 versus 30PD; #P < 0.05 versus 50PD.
