Fig. 4: LncRNA HCG15 in exosomes released from hypoxic cells contributed to cardiomyocyte apoptosis and the production of inflammatory cytokines.

A qRT-PCR was performed to determine the expression of HCG15 in AC16 cells after transfection with HCG15 siRNAs. B qRT-PCR was performed to detect the expression of HCG15 in AC16 cells after transfection with HCG15 siRNA and subsequent incubation with Exo-H. C MTT assays detected the proliferation of AC16 cells after transfection with HCG15 siRNA and subsequent incubation with Exo-H. TUNEL staining (D) and flow cytometry (E) were performed to measure the apoptosis of AC16 cells after the indicated treatment. F ELISAs were used to measure the production of inflammatory cytokines in AC16 cells after the indicated treatment. *p value < 0.05, ***p value < 0.001. Each assay was performed in triplicate.
