BRD4 promotes hepatic stellate cells activation and hepatic fibrosis via mediating P300/H3K27ac/PLK1 axis.

Hepatic fibrosis (HF) is a reversible wound-healing response characterized by excessive extracellular matrix (ECM) deposition and secondary to persistent chronic injury. Bromodomain protein 4 (BRD4) commonly functions as a "reader" to regulate epigenetic modifications involved in various biological and pathological events, but the mechanism of HF remains unclear. In this study, we established a CCl-induced HF model and spontaneous recovery model in mice and found aberrant BRD4 expression, which was consistent with the results in human hepatic stellate cells (HSCs)- LX2 cells in vitro.

Berberine Ameliorates Abnormal Lipid Metabolism via the Adenosine Monophosphate-Activated Protein Kinase/Sirtuin 1 Pathway in Alcohol-Related Liver Disease.

Alcoholic fatty liver disease (AFLD) is an early stage of alcohol-related liver disease characterized by abnormal lipid metabolism in hepatocytes. To date, to our knowledge, there have been no effective strategies for preventing or treating alcohol-related liver disease besides alcohol abstinence. Berberine (BBR) is the main bioactive ingredient extracted from traditional Chinese medicines, such as Coptis and Scutellaria, which protect liver function and relieve liver steatosis.

P2X7 Receptor in Alcoholic Steatohepatitis and Alcoholic Liver Fibrosis.

Alcoholic liver disease is one of the most common chronic liver diseases in the world. It is a liver disease caused by prolonged heavy drinking and its main clinical features are nausea, vomiting, enlargement of the liver, and jaundice. Recent studies suggest that Kupffer cell-mediated inflammatory response is a core driver in the development of alcoholic steatohepatitis and alcoholic liver fibrosis.

CD73 aggravates alcohol-related liver fibrosis by promoting autophagy mediated activation of hepatic stellate cells through AMPK/AKT/mTOR signaling pathway.

CD73 is a membrane-bound glycoprotein that can dephosphorylate AMP to adenosine. Increasing evidence has shown that CD73 is involved in the occurrence and development of liver fibrosis. However, the potential mechanism by which CD73 affects the progression of alcohol-related liver fibrosis (ALF) remains unknown.

Blocking P2X4 purinergic receptor attenuates alcohol-related liver fibrosis by inhibiting hepatic stellate cell activation through PI3K/AKT signaling pathway.

Alcoholic liver fibrosis（ALF）, as a liver disease caused by long-term alcoholism, attracts international attention. Activation of hepatic stellate cells is a key step in the development of alcoholic-associated liver fibrosis. Increasing studies have shown that P2X4 receptor, as a component of purinoceptor family in adenosine pathway, plays an important role in numerous liver diseases.

Blockade of the P2Y2 Receptor Attenuates Alcoholic Liver Inflammation by Targeting the EGFR-ERK1/2 Signaling Pathway.

Purpose: It is well known that inflammation plays a key role in complex pathological progressions of alcohol-associated liver disease (ALD). To date, effective therapy for ALD is lacking. P2Y2 receptor (P2Y2R), a G protein-coupled P2Y purinergic receptor, represents a novel pharmacological target in many inflammations.

Adenosine receptor A2B mediates alcoholic hepatitis by regulating cAMP levels and the NF-KB pathway.

Alcoholic hepatitis is a serious form of liver damage. Inflammation is a key factor in alcoholic hepatitis and plays a key role in the progression of alcoholic liver disease. Adenosine receptor A2B (A2BAR) is a member of the adenosine receptor family and generally considered to be a negative regulator of the inflammatory response.

CD73 Attenuates Alcohol-Induced Liver Injury and Inflammation via Blocking TLR4/MyD88/NF-κB Signaling Pathway.

Background: Alcoholic liver disease (ALD) is liver damage caused by long-term drinking. Inflammation plays a central role in the progression of ALD. CD73 is a ubiquitously expressed glycosylphosphatidylinositol-anchored glycoprotein that is a key enzyme that converts ATP into adenosine.

Circular RNA CREBBP Suppresses Hepatic Fibrosis Targeting the hsa-miR-1291/LEFTY2 Axis.

CircRNAs (circRNAs) are commonly dysregulated in a variety of human diseases and are involved in the development and progression of cancer. However, the role of circRNAs in hepatic fibrosis (HF) is still unclear. Our previous high throughput screen revealed changes in many circRNAs in mice with carbon tetrachloride (CCl4)-induced HF.

Review on Biological Characteristics of Kv1.3 and Its Role in Liver Diseases.

The liver accounts for the largest proportion of macrophages in all solid organs of the human body. Liver macrophages are mainly composed of cytolytic cells inherent in the liver and mononuclear macrophages recruited from the blood. Monocytes recruitment occurs mainly in the context of liver injury and inflammation and can be recruited into the liver and achieve a KC-like phenotype.

CD39-mediated ATP-adenosine signalling promotes hepatic stellate cell activation and alcoholic liver disease.

CD39 is associated with diverse physiological and pathological processes, including cell proliferation and differentiation. Adenosine triphosphate (ATP) is hydrolysed to adenosine by different enzymes including ecto-nucleoside triphosphate diphosphohydrolase-1/ENTPD1 (CD39) and ecto-5'-nucleotidase (CD73), regulating many physiological and pathological processes in various diseases, but these changes and functions in alcoholic liver disease are generally unknown. In this study, an alcoholic liver disease model in vivo was induced by ethanol plus carbon tetrachloride(CCl) administered to C57BL/6 mice, who were the intraperitoneally injected with the CD39 inhibitor sodium polyoxotungstate (POM1) or colchicine from the 5th week to the 8th week.

CD73 regulates hepatic stellate cells activation and proliferation through Wnt/β-catenin signaling pathway.

Alcoholic liver fibrosis (ALF) is commonly associated with long-term alcohol consumption and the activation of hepatic stellate cells (HSCs). Inhibiting the activation and proliferation of HSCs is a critical step to alleviate liver fibrosis. Increasing evidence indicates that ecto-5'-nucleotidase (CD73) plays a vital role in liver disease as a critical component of extracellular adenosine pathway.

LEFTY2 alleviates hepatic stellate cell activation and liver fibrosis by regulating the TGF-β1/Smad3 pathway.

Activated hepatic stellate cells (HSCs) are the major cell type involved in the deposition of extracellular matrix (ECM) during the development of hepatic fibrosis. In this study, we revealed that left-right determination factor 2 (LEFTY2), one of the proteins belonging to the transforming growth factor-β (TGF-β) protein superfamily, was remarkedly decreased in human hepatic fibrosis tissues and in a carbon tetrachloride (CCl)-induced liver fibrosis mouse model. In addition, TGF-β1 treatment markedly reduced the level of LEFTY2 in HSCs.

Regulation of CD39 expression in ATP-P2Y2R-mediated alcoholic liver steatosis and inflammation.

Inflammation plays a central role in the progression of alcoholic liver disease. ATP-P2Y2R signaling and CD39 play an important role in various diseases, but little is known about their role in alcoholic liver steatosis and inflammation. As a transmembrane hydrolase, CD39 hydrolyzes ATP, while the mutual regulation of CD39 and ATP-P2Y2R in alcoholic steatohepatitis is poorly understood.

Application of Herbal Traditional Chinese Medicine in the Treatment of Acute Kidney Injury.

Acute kidney injury (AKI) is a clinical syndrome characterized by a rapid loss of renal function, which may further develop into chronic kidney damage (CKD) or even end-stage renal disease (ESRD). AKI is a global health problem associated with high morbidity and costly treatments, and there is no specific or effective strategy to treat AKI. In recent years, Traditional Chinese Medicine (TCM) has attracted more attention, with lines of evidence showing that application of TCM improved AKI, and the mechanisms of action for some TCMs have been well illustrated.
