Abstract: OBJECTIVE: Granules (QSG) on adenine-induced renal fibrosis in mice and in uric acid (UA)-stimulated NRK-49F cells and its mechanism for regulating exosomes, miR-330-3p and CREBBP. METHODS: -SMA, FN, and E-cad were analyzed. Dual luciferase reporter assay was employed to examine the targeting relationship between miR-330-3p and CREBBP, whose expressions were detected by RT-qPCR and Western blotting in treated NRK-49F cells. RESULTS: -SMA, and FN increased and Ecad decreased in the mouse models but these changes were reversed by QSG treatment. QSG treatment obviously alleviated renal fibrosis in the mouse models. Intravenous injection of adeno-associated viral vector obviously inhibited miR-330-3p, increased CREBBP levels, and reduced fibrosis in the mouse models. Dual luciferase assay confirmed CREBBP as a target of miR-330-3p, which was consistent with the results of the cell experiments. CONCLUSION: QSG inhibits renal fibrosis in mice by regulating the exosomes, reducing miR-330-3p levels, and increasing CREBBP expression.
