- Metabolic-associated fatty liver disease (MAFLD) is a common chronic liver disease caused by lipid accumulation in hepatocytes, and multiple deubiquitinating enzymes (DUBs) have been reported to play roles in the pathogenesis of MAFLD. However, the role of ubiquitin-specific protease 47 (USP47) in MAFLD remains unclear. - Source: PubMed

Cao YaWen ZhengrongChen JiachuanZhang HuangyanLi QiaoyangHu Zongqiang - Liver fibrosis is a pathological process caused by excessive deposition of extracellular matrix (ECM) in the liver stimulated by chronic injury or inflammation. Nuclear pore protein 85 (NUP85) has been implicated in the development of various liver diseases. However, its involvement in liver fibrosis remains unclear. The present study aimed to explore the role of NUP85 in liver fibrosis. The expression level of NUP85 was found to be elevated in the liver tissues of liver fibrosis patients and mice. Knockdown of NUP85 not only ameliorated liver injury and collagen deposition, but also suppressed endoplasmic reticulum stress (ERS). Conversely, the opposite pathological and biochemical changes are observed with NUP85 overexpression. Mechanistically, NUP85 competitively binds ubiquitin-specific peptidase 47 (USP47) to apoptosis signal-regulating kinase 1 (ASK1), deubiquitinates lysine residue 805 of ASK1, and regulates the activation of ASK1, thereby exacerbating collagen deposition and ERS. Furthermore, we developed a CREKA-coupled liposome as a targeted delivery system to deliver Mogroside V (MV), a pharmacological inhibitor of NUP85, to activated HSCs and attenuate liver fibrosis. Taken together, the present study demonstrated that NUP85 is a novel regulator of liver fibrosis and that the NUP85-USP47-ASK1 signaling pathway might be a strategy for therapeutic intervention. - Source: PubMed

Yang DashuaiYang HaoranPan LinxinTian ChangZuo FuchengHuang ShileiLi XianruiChen MingQian ChengWang JieChen ZhaolinXu Tao - Diabetic cataract has become the second-largest blind causing disease among the complications of diabetes mellitus in eyes. Ferroptosis is responsible for many complications associated with diabetes mellitus, but the role of ferroptosis in diabetic cataract has not yet been studied. Here, we first ascertained that ferroptosis was triggered during diabetic cataract, as identified by elevated levels of transferrin receptor protein 1 (CD71) and solute carrier family 7 member 11 (SLC7A11), lipid peroxidation , total iron and Fe under conditions of excessive glucose. Moreover, voltage-dependent anion channel 3 (VDAC3) was found to decrease under high levels of glucose both in vivo and in vitro. VDAC3 knockdown resulted in increased reactive oxygen species (ROS) levels and reduced nicotinamide adenine dinucleotide (NADH) levels, indicating that decreased VDAC3 modulates ferroptosis in diabetic cataract via ROS-induced lipid peroxidation. Furthermore, we verified that the level of ubiquitin-specific peptidase 47 (USP47) was decreased in high glucose-treated lens epithelial cells. We found that USP47 bound to and modulated the deubiquitination of VDAC3. This binding between USP47 and VDAC3 was weakened and VDAC3 was subsequently ubiquitinated and degraded under high glucose conditions, which ultimately resulted in ferroptosis and diabetic cataract. Overall, we verified that the USP47-VDAC3-ROS/NADH axis regulates ferroptosis in high glucose-treated lens epithelial cells (LECs) and in an animal model of diabetic cataract. Our findings increase the understanding of human diabetic cataract and provide important mechanistic insight into potential ferroptosis treatments in medicine and technology for treating diabetic cataract. - Source: PubMed

Xu HaoranWang WenjingLi JianqiaoZhao XiaofeiZhang Han - Solid tumors frequently preferentially metastasize to specific organs. Metabolites within metastatic niches have emerged as critical regulators of organotropic metastasis. In this study, we found that palmitic acid (PA) accumulated in both premetastatic and macrometastatic lung niches. Lung-preferential metastatic breast cancer (LM-BC) cells secreted exosomal USP47 that was taken up by lung-resident alveolar type II epithelial cells and enhanced fatty acid synthesis via YAP activation, resulting in PA enrichment and subsequent lung metastasis. ACSL5 in LM-BC cells facilitated PA adaptation by inducing COX2-mediated PGE2 accumulation and subsequent activation of the PI3K/AKT and ERK signaling pathways through EP4, which promoted cell survival and lung metastasis. Moreover, ACSL5 boosted levels of palmitoyltransferases, further enhancing COX2 expression, which could be inhibited by the palmitoylation inhibitor 2-bromopalmitate. Notably, the enrichment of PA, accumulation of PGE2, and activation of the ACSL5/COX2/EP4 axis in lung metastases of patients with breast cancer correlated with poorer clinical outcomes. Limiting PA intake or targeting the ACSL5/COX2/EP4 axis enhanced paclitaxel efficacy in a breast cancer mouse model. Collectively, these findings highlight the critical role of PA and ACSL5/COX2/EP4 signaling in lung metastasis, which can act as promising targets for enhancing the efficacy of chemotherapy in patients with breast cancer with lung metastasis. - Source: PubMed

The epigenetic regulator HDAC2 has been implicated, but the upstream regulatory mechanisms and precise downstream pathways are unclear. Using a CS-induced mouse atrophy model and C2C12 myotubes treated with cigarette smoke extract (CSE), we systematically investigated the role of USP47/HDAC2/CYP1A1/ROS axis through gain/loss-of-function studies, RNA-seq, ChIP-qPCR, co-immunoprecipitation, and ubiquitination assays. HDAC2 was downregulated in atrophic muscle, and its overexpression mitigated CS-induced atrophy, improved grip strength, and enhanced muscle regeneration. HDAC2 acted as a transcriptional repressor of CYP1A1 by deacetylating H3K9 and H3K27 at the promoter, thus curtailing ROS-driven excessive autophagy. We further discovered that the deubiquitinase USP47 is the key upstream regulator of HDAC2. USP47 directly interacted with HDAC2, promoted its deubiquitination, and enhanced its protein stability. Consequently, USP47 overexpression phenocopied the benefits of HDAC2 overexpression, which were effectively nullified by restoring CYP1A1 expression. In conclusion, we delineate a previously unrecognized signaling axis wherein USP47 stabilizes HDAC2 to inhibit the CYP1A1/ROS/autophagy cascade, ultimately protecting against CS-induced skeletal muscle atrophy. Targeting the USP47-HDAC2 interface presents a novel therapeutic strategy for combating muscle wasting in COPD. - Source: PubMed
