Amelioration of nonalcoholic fatty liver disease by inhibiting the deubiquitylating enzyme RPN11 (MeRIP-m6A-mRNA-seq)

ABSTRACT: Nonalcoholic fatty liver disease (NAFLD) including its more severe manifestation, nonalcoholic steatohepatitis (NASH), is a global public health challenge with no approved pharmacological therapies. Here, we reveal an indispensable role for the deubiquitinating enzyme RPN11 in the development of NAFLD and NASH. Ablation of hepatic RPN11 markedly protected mice from several diets-induced liver steatosis, insulin resistance and steatohepatitis, whereas RPN11 overexpression had the opposite effects. Mechanistically, RPN11 interacts with and stabilizes METTL3 via deubiquitination initiated at lysine 241, to increase the m6A modification and expression of acyl-CoA synthetase short chain family member 3 (Acss3). RPN11-Acss3 axis generates propionyl-CoA and functions in histone propionylation to transcriptionally upregulate lipid metabolism-related genes. Of pathophysiological significance, RPN11-METTL3-Acss3-histone propionylation modification pathway is activated in the livers of patients with NAFLD and positively correlated with hepatic triglyceride contents. More importantly, pharmacological inhibition of RPN11 by Capzimin showed dramatic beneficial effects in ameliorating NAFLD, NASH and related metabolic disorders in mice. Capzimin also reduces intracellular lipid contents in human primary hepatocytes cultured in 2D and 3D spheroids. Together, these results demonstrate that RPN11 is essential for the development of NAFLD/NASH and that suppressing RPN11 has therapeutic potential for the treatment.

Amelioration of nonalcoholic fatty liver disease by inhibiting the deubiquitylating enzyme RPN11 (mRNA-seq db vs. lean)

Transcriptome profiling of human non-alcoholic fatty liver disease

Project description:Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide. Nonalcoholic steatohepatitis (NASH), the progressive form of NAFLD, and advanced fibrosis are associated with poor outcomes but their molecular pathogenesis is not fully elucidated. Global RNA sequencing of snap frozen liver tissue from 98 patients with biopsy-proven NAFLD was performed. Unsupervised hierarchical clustering well-distinguished NASH from NAFL, and NASH patients exhibited molecular abnormalities reflecting their pathological features. Transcriptomic analysis identified multiple secreted proteins upregulated in NASH and/or advanced fibrosis

circRNA expression profiles of fibroblasts: normal vs. NASH cirrhosis

Project description:The progression from steatosis to nonalcoholic steatohepatitis (NASH) in nonalcoholic fatty liver disease (NAFLD) patients is one of the major causes of liver-related death worldwide and have limited effective therapies. We comparing the circular RNomics of liver fibroblasts isolated from patients with NAFLD-caused cirrhosis and the ones without NAFLD.

Whole transcriptome profiling of Japanese nonalcoholic fatty liver disease cohort.

Project description:Nonalcoholic steatohepatitis (NASH) is a severe form of nonalcoholic fatty liver disease (NAFLD) that is characterized by hepatic steatosis, inflammation, hepatocellular injury, and fibrosis, which lead to progressed cirrhosis and hepatocellular carcinoma. Despite its increasing prevalence on a global scale, the pathogenesis of NASH progression is not well understood. To elucidate the underlying mechanisms of NASH progression, we conducted transcriptome analyses of Japanese NAFLD cohort in our facility.

Dyslipidemia Alters HDL Metabolism and Function in NAFLD

Project description:Dyslipidemia and inflammation play key roles in the pathogenesis of both nonalcoholic fatty liver disease (NAFLD) and atherosclerosis. NAFLD, particularly its severe form nonalcoholic steatohepatitis (NASH) is associated with increased cardiovascular disease (CVD) risk. HDL (high density lipoprotein- also a CVD risk) are decreased in NAFLD but whether HDL function is abnormal in NAFLD is unknown. Furthermore, it is unknown whether dyslipidemia contributes to reduced HDL function in NAFLD and whether hepatic inflammation further impairs HDL function in patients with NASH. Therefore, the aim of this study was to investigate HDL function and to examine the effect of dyslipidemia and inflammation on HDL metabolism in patients with biopsy-proven simple steatosis (SS) and NASH. RESULTS: Compared to controls, SS and NASH subjects had significantly higher levels of plasma triglyceride, insulin, and were more insulin resistant (HOMA, P<0.05) with no differences in total cholesterol, HDL cholesterol, ApoB100 and ApoAI levels. NAFLD patients had increased production and degradation rates of both HDLc and ApoAI that resulted in their levels remaining stable. The degradation rates also were increased of other HDL proteins, including ApoAII, ApoAIV, vitamin D-binding protein, and complement 3 (all P<0.05). NAFLD patients had increased activities of LCAT and CETP, indicating altered HDL lipidation. NAFLD induced alterations in HDL metabolism were associated with reduced anti-oxidant but increased pro-inflammatory activity of HDL. However, no differences were observed in either HDL function or the kinetics of HDLc and HDL proteins between SS and NASH subjects.

Exosomal microRNA expression profiles of NASH: normal vs. NASH

Project description:Non-alcoholic fatty liver disease (NAFLD) is a predominant form of chronic liver disease, affecting nearly 25 % of the global population. The progression from steatosis to nonalcoholic steatohepatitis (NASH) in NAFLD patients is one of the major causes of liver-related death worldwide. We assessed the miRNA expression profiles of the exosomes derived from the peripheral blood of NASH patients or healthy controls.

Nonalcoholic steatohepatitis in adolescents undergoing bariatric surgery

Project description:The genomic landscape of hepatic tissue affected by nonalcoholic steatohepatitis (NASH) in severely obese adolescents undergoing bariatric surgery is unknown. Our purpose here was to uncover genomic profiles of obese controls, and obese cases with nonalcoholic fatty liver disease (NAFLD), borderline nonalcoholic steatohepatitis, and definite nonalcoholic steatohepatitis, in order to clarify molecular functions, biological processes, and pathways that are dysregulated in nonalcoholic steatohepatitis in the severely obese adolescent. In a prospective observational cohort study, we have intra-operatively obtained 165 liver samples; of these 67 were submited for microarray analysis. Through ANOVA, we found 8648 genes with differential regulation between the four histologies; from these, we uncovered gene signatures shared between borderline and definite nonalcoholic steatohepatitis, and gene sets with differential effects between borderline and definite.
