FGF1 and familial dilated cardiomyopathy: Studies have shown that FGF1 has a wide range of physiological functions, such as antioxidant damage (Pena et al., 2017), induction of endothelial and smooth muscle cell proliferation and angiogenesis (Zhao et al., 2016), promotion of tissue wound repair (Xu et al., 2018), neurotrophic regeneration (Tsai et al., 2015), etc. Therefore, FGF1 has a great potential in the prevention and treatment of DCM.
