Figure 5.miR-92a-3p impeded exosome^Hypoxia anti-senescent effect against Dox. (A) miR-92a-3p mRNA levels were analyzed by qRT-PCR. ^*P < 0.05 versus miR-92a mimic. (B) Cell cycle distribution was analyzed. (C and D) p53 and p21 mRNA levels were analyzed by qRT-PCR. (E) Representative images of the SA-β-gal staining. (F) Percentage of β-gal-positive cells. Each column represents the mean ± SD of three independent experiments. ^*P < 0.05 versus control; ^▲P < 0.05 versus Dox; ^□P < 0.05 versus Dox + exosome^Hypoxia + miR-92a-3p mimic.
