USP2 WT transfection promoted TGF1-induced nuclear localization of SMAD3, and increased SMAD3-mediated transcriptional activity, the protein level of TGFBR1 , and the mRNA level of TGF signaling target genes ( COL1A1, COL1A2, SERPINE1 , and SMAD7 ), while USP2 K447R abolished these effects (Fig
7 Recent advances and clinical trials for neurodegenerative diseases 7.1 NP-based siRNA delivery for ADs The instability of siRNA therapy in the circulation and the fact that it is unable to reach target cells in the central nervous system (91, 92) because of the BBB poses the biggest hurdle in siRNA therapy
Its multifaceted mechanisms of action include antioxidative effects, anti-inflammatory properties, modulation of lipid metabolism, improvement of insulin sensitivity, and mitochondrial protection, all of which contribute to its hepatoprotective potential
