Figure 4. LncRNA-MALAT1 directly inhibited miR-92a-3p. (A) Heat map of microRNAs (miRs) differentially regulated by exosome^Hypoxia in Dox-treated cardiomyocytes. (B) qRT-PCR validation of the differentially regulated miRs in cardiomyocytes. ^*P < 0.05 versus Dox. (C) Binding sites of lncRNAs and miRs. (D) Dual-luciferase reporter. ^*P < 0.05 versus miR-92a-3p mimic in the WT group. (E) miR-92a-3p mRNA levels were analyzed by RT-qPCR. ^*P < 0.05 versus control; ^▲P < 0.05 versus Dox; ^□P<0.05 versus Dox + exosome^{Hypoxia+siRNA-lncRNA-MALAT1}.
