TGFB1 and hydrops fetalis: As reported, NEAT1 was significantly expressed in both HF patients and TAC-induced HF mouse models, inhibition of its expression attenuated the TGF-β1-induced cardiac fibrosis, GSK126 (an EZH2 inhibitor) weakened TGF-β1-induced downregulation of Smad7 expression and upregulation of p-Smad2/3, and upregulation of Smad7 reversed the cardiac fibrosis caused by NEAT1 over-expression (Zhang et al., 2020b).
