Prunella vulgaris aqueous extract (PVAE) can downregulate miR-34a level, inhibit the activation of HSCs, and regulate the expression of TIMP-1, MMP-2, and MMP-13, promoting the degradation of collagen, and alleviating hepatic fibrosis (Hu et al., 2016); Paclitaxel has been applied to treat fibrosis by downregulating miR-34a, upregulating SIRT1, and inhibiting p53 activation and TGF-β1/Smads signal pathway (Song et al., 2019). The gene discussed is TP53; the disease is Hepatic fibrosis.
