OSM receptor Oβ knockout (Oβ-KO) attenuated DCM injury (A) Representative images as evaluated by echocardiography. (B) TEM showed relieved mitochondria impairment in the DCM-Oβ−/− group and OSM could no longer lead to mitochondria impairment in DCM-Oβ−/− group mice (scale bar = 2 μm). (C) Sirius red staining showed decreased fibrosis area in the DCM-Oβ−/− group compared with the DCM group, and no increased fibrosis area was detected in the DCM-Oβ−/− +OSM group (magnification, ×400). (D–G) Statistical analysis of EF, FS, ±LV dp/dt max, LVEDV and LVESV. (H) Statistical analysis of fibrosis area. *P < 0.05 vs. DCM group.
