Project description:To understand the mechanisms of NASH, we detected mRNA level in human NASH (n=5) and normal tissue (n=5) by RNA-Seq. The normal tissues were collected from the patients who received hepatic haemangioma surgery, and the steatotic liver samples were collected from the eligible patients who received bariatric surgery underwent liver biopsy or surgical resection at Nanjing Drum Hospital (Nanjing,China). This RNA-Seq might help us to find the important target genes and signaling pathway during NASH.
Project description:Non-alcoholic fatty liver disease (NAFLD) is characterized by a series of pathological changes that can progress from simple fatty liver disease to non-alcoholic steatohepatitis (NASH). The objective of this study is to describe changes in global gene expression associated with the progression of NAFLD. This study is focused on the expression levels of genes responsible for the absorption, distribution, metabolism and excretion (ADME) of drugs. Differential gene expression between three clinically defined pathological groups; normal, steatosis and NASH was analyzed. The samples were diagnosed as normal, steatotic, NASH with fatty liver (NASH fatty) and NASH without fatty liver (NASH NF). Genome-wide mRNA levels in samples of human liver tissue were assayed with Affymetrix GeneChipM-. Human 1.0ST arrays
Project description:To investigate the function of read-through circRNAs in liver, we obtained human NASH liver tissues and normal liver tissues patients without NAFLD undergoing surgery for hepatic hemangioma.Patients with positive hepatitis B surface antigen or anti-hepatitis C virus (HCV) antibody with detectable HCV RNA, excessive alcohol consumption (20 g/day in men or 10 g/day in women), secondary fatty liver (e.g., use of systemic steroids or tamoxifen), or malignancies before baseline were excluded. We then performed exome capture mRNA sequencing using livers from three NASH patients and three patients with hepatic hemangioma.
Project description:We performed RNA-seq analysis of pooled RNA extracted from liver of mice fed normal chow (control), WDF (NASH), and WDF+TH (TH-treated NASH).
Project description:Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of disease that ranges from simple steatosis, to inflammatory form non-alcoholic steatohepatitis (NASH), cirrhosis, and up to hepatocellular carcinoma. While NASH usually takes decades to develop at a rate of one stage per seven years, in the case of post-trasplant NASH (pt-NASH) develops fibrosis much more rapidly, with almost 50% of liver transplant recipients presenting stage 3 fibrosis by 5 years post-transplant. Archived fresh-frozen transplanted liver biopsy samples from four liver biopsy samples with evidence of NASH (2 recurrent and 2 de novo), two with simple steatosis (both de novo), and five with normal histology as controls had their transcriptome sequenced in two batches for deeper coverage.
Project description:The tumor microenvironment (TME) plays an important role in tumorigenesis1. The TME is usually studied in tumor tissue and in relation to tumor progression2,3, which can limit understanding of how the TME is involved in processes associated with initial tumorigenesis as well as tumor recurrence and metastasis after surgery. To describe the underlying mechanisms of human hepatocellular carcinoma (HCC) occurrence and progression, we propose a new concept, the peritumor microenvironment (PME). We collected normal (all biochemical indicators of liver function, imaging examination and histopathology examination were normal) and peritumor (The liver tissues adjacent to the tumor were approximately 2 cm away from the tumor and were taken from patients with HCC who did not receive tumor radiotherapy, tumor chemotherapy or targeted drug therapy before surgery) to perform a proteomic characterization of the PME in peritumor liver tissues.
Project description:Gene expression profiling reveals a potential role of isorhamnetin in the mitigation of NASH features including steatosis, liver injury, and fibrosis Microarray gene expression profiling was conducted for technical replicates of healthy liver as control (CTL), NASH-induced (NASH), NASH-induced treated with isorhamnetin for 14 days (50 mg/kg of body weight) (NASH+ISO) liver tissues to identify its effect in the regulation of pathways involved in pathologic features of 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.
