Abstract:

Heart failure characterized by cardiac remodeling is a global problem. Angiotensin II (Ang II) induces cardiac inflammation and oxidative stress, which also is implicated in the pathophysiology of adverse collagen accumulation-induced remodeling. Kaempferol (KPF), a kind of flavonoid compounds, is capable of anti-inflammatory and antioxidant activities. However, the target of KPF still remains blurred. In this study, we investigated the effect of KPF on Ang II-induced collagen accumulation and explored the underlying mechanisms. Our results suggested that KPF prevented Ang II-induced cardiac fibrosis and dysfunction, in mice challenged with subcutaneous injection of Ang II. In culture cells, KPF significantly reduced Ang II-induced collagen accumulation. Furthermore, KPF remarkably decreased inflammation and oxidative stress in Ang II-stimulated cardiac fibroblasts by modulating NF-κB/mitogen-activated protein kinase and AMPK/Nrf2 pathways.
