Stem Cell-Derived Exosomes Prevent Aging-Induced Cardiac Dysfunction through a Novel Exosome/lncRNA MALAT1/NF-κB/TNF-α Signaling Pathway

Figure 6

EXO prevents cell senescence through the regulation of lncRNA MALAT1. (a) Dual luciferase assay revealed siRNA-MALAT1 reversed the EXO’s effects on NF-κB activity in H2O2-treated cells. (b) siRNA-MALAT1 blocked EXO’s effect on p-p65 expression. (c) siRNA-MALAT1 blocked EXO’s effect on TNF-α expression. (d) siRNA-MALAT1 blocked EXO’s effect on p21 expression. (e) Immunohistochemistry staining of β-gal in cardiomyocytes treated with siRNA-MALAT1. (f) Edu staining for cell proliferation treated with siRNA-MALAT1. /group, , , and .
