However, the latent mechanisms remain insufficiently resolved. In the present research, we evaluated the therapeutic effects of baicalein on isoprenaline (ISO)-induced heart failure and investigated the possible underlying mechanisms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Toxicity was analyzed in zebrafish embryos and mouse atrial myocytes HL-1. The MTT assay was used to evaluate the effectiveness of baicalein. DCFH-DA was used as a fluorescence probe to detect intracellular reactive oxygen species (ROS). Superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-Px) levels were measured using SOD, MDA and GSH-Px commercial kits. Adult BALB\/c mice were randomized into six groups of ten animals each. Cardiac function was analyzed by echocardiographic images. Structural changes were analyzed by hematoxylin &amp; eosin (HE) staining, Masson staining and TUNEL staining. The mechanism of baicalein was investigated by analyzing relative signaling pathways through western blotting.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Our studies show that baicalein both significantly reduces ISO-induced oxidative stress, apoptosis and cardiac fibrosis in vitro and vivo, this phenomenon was related to mitochondrial fusion\/fission balance and inhibiting GRP78\/CHOP pathway.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Our results suggested that baicalein controls mitochondrial fusion\/fission balance and inhibits GRP78\/CHOP pathway, thus exerting therapeutic effects in ISO-induced heart failure in HL-1 cells and BALB\/c mice.
