Open AccessMETTL3-mediated macrophage exosomal NEAT1 contributes to hepatic fibrosis progression through Sp1/TGF-β1/Smad signaling pathway
Hepatic fibrosis (HF) is caused by chronic hepatic injury and is characterized by hepatic stellate cells (HSCs) activation. Studies focusing on the function of exosomes derived from macrophages in HF progressi...

Open AccessThe METTL3/MALAT1/PTBP1/USP8/TAK1 axis promotes pyroptosis and M1 polarization of macrophages and contributes to liver fibrosis
Pro-inflammatory M1 macrophages, via activating hepatic stellate cells, contribute to liver fibrosis. In this study, we examined the mechanism and the significance of a signaling axis, METTL3/MALAT1/PTBP1/USP8...
