Chronic hepatitis C (CHC) is a leading cause of hepatic fibrosis and cirrhosis. The level of fibrosis is traditionally established by histology and prognosis is estimated using fibrosis progression rates (FPRs; annual probability of progressing across histological stages). However, newer non-invasive alternatives are quickly replacing biopsy. One alternative, transient elastography (TE), quantifies fibrosis by measuring liver stiffness (LSM). Given these developments, the purpose of this study was (1) to estimate prognosis in treatment-naïve CHC patients using TE-based liver stiffness progression rates (LSPR) as an alternative to FPRs and (2) to compare consistency between LSPRs and FPRs...

Activation of the adiponectin (APN) signaling axis retards liver fibrosis. However, understanding of the role of AdipoR1 and AdipoR2 in mediating this response is still rudimentary. Here, we sought to elucidate the APN receptor responsible for limiting liver fibrosis by employing AdipoR1 and AdipoR2 knock-out mice in the carbon tetrachloride (CCl4) model of liver fibrosis. In addition, we knocked down receptor function in primary hepatic stellate cells (HSCs) in vitro. Following the development of fibrosis, AdipoR1 and AdipoR2 KO mice had no quantitative difference in fibrosis by Sirius red staining...

BACKGROUND AND CLINICAL SETTING: Lysosomal acid lipase deficiency is an autosomal recessive storage disease caused by mutations in the LIPA gene. The accumulation of cholesteryl esters and triglycerides in hepatocytes lead to hepatomegaly with progressive fibrosis and liver cirrhosis. Characteristically, patients have a hepatomegaly combined with high serum levels of cholesterol, LDL-cholesterol and in some cases triglyceride, whereas HDL-cholesterol is decreased. Histologically, hepatocytes show a microvesicular steatosis with typically ballooned Kupffer cells...

Thrombotic diseases have become a global burden due to morbidity, mortality, and disability. Traditional Chinese medicine has been proven effective in removing blood stasis and promoting blood circulation, but the exact mechanisms remain unclear. Plasminogen activator inhibitor-1 (PAI-1) is a natural inhibitor of tissue-type and urokinase-type plasminogen activators. In this study, we screened four fractions of Resina Draconis (a traditional Chinese medicine) extract for PAI-1 inhibitory activity. Bioactivity-guided purification and chromogenic substrate-based assay led to the identification of loureirin B as the major PAI-1 inhibitor, with an IC50 value of 26...

Abdominal symptoms are a hallmark of Cystic fibrosis (CF). Yet, their association with morphological abnormalities of different abdominal organs is still poorly understood. Aim was therefore to relate these symptoms, assessed with a questionnaire, to findings in abdominal ultrasound (US). In 114 CF patients of all ages, findings in US considering seventeen specific parameters were related to abdominal symptoms compiled with our novel CF-specific 26-modal symptom score (CFAbd-Score). US abnormalities were detected in 95% of the patients...

Liver fibrosis represents the consequences of a sustained wound healing response to chronic liver injury which could be caused by viral, autoimmune, drugs, and so on. Unfortunately, there was no effective therapy available for liver fibrosis in clinic. In this study, we identified the anti-fibrotic effects of 1,7-dihydroxy-3,4,8-trimethoxyxanthone (ZYC-1) on the dimethylnitrosamine (DMN)-induced rat model. ZYC-1 was isolated from Swertia punicea Hemsl and was administrated to DMN-induced rat model. ZYC decreased the hyaluronic acid (HA), type IV collagen (CIV) and hydroxyproline (Hyp) levels and inhibited the expression of α smooth muscle actin (α-SMA) and transforming growth factor beta 1 (TGF-1β)...

Non-alcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease in the developed world (15% to 40% of the adult population). Introduction of lifestyle changes including dietary intervention and increased physical activity is most often the first-line treatment and is intended to support not only the treatment of liver disease, but also for diseases associated with obesity, insulin resistance, diabetes and dyslipidemia. In addition to well-known metformin, there are new classes of antidiabetic drugs, including GLP-1analog, SGLT-2 antagonist, pioglitazon...

Inhibition of microRNA-21 (miR-21) prevents necroptosis in the mouse pancreas. Necroptosis contributes to hepatic necro-inflammation in the common bile duct ligation (BDL) murine model. We aimed to evaluate the role of miR-21 in mediating deleterious processes associated with cholestasis. Mechanistic studies established a functional link between miR-21 and necroptosis through cyclin-dependent kinase 2-associated protein 1 (CDK2AP1). miR-21 expression increased in the liver of primary biliary cholangitis (PBC) patients and BDL wild-type (WT) mice at both 3 and 14 days...

OBJECTIVES: Circulating cell-free DNA (cfDNA) is a potential biomarker for tumor diagnosis. Hepatocyte damage is characteristic component of the pathobiology of hepatocellular carcinoma (HCC), which would be expected to result in substantial leakage of cfDNA into the circulation. However, the diagnostic value of cfDNA levels for HCC remains unclear. METHODS: Plasma samples were collected from 24 HCC patients and 62 HBV-related liver fibrosis patients. Plasma cfDNA levels was quantified by Qubit method...
