HBx Protein Contributes to Liver Carcinogenesis by H3K4me3 Modification Through Stabilizing WD Repeat Domain 5 Protein.

Background And Aims: Cancer is typically considered as a genetic and epigenetic disease. Although numerous studies have indicated that an aberrant structure, function, or expression level of epigenetic enzymes contribute to many tumor types, precisely how the epigenetic mechanisms are involved in the hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) remains unknown.

Approach And Results: In this study, we found that the WD repeat domain 5 protein (WDR5)-a core subunit of histone H3 lysine 4 methyltransferase complexes, which catalyze the generation of histone H3 lysine 4 trimethylation (H3K4me3) modification-is highly expressed in HBV-related HCC and promotes HCC development.

[HBsAg loss with Pegylated-interferon alfa-2a in hepatitis B patients with partial response to nucleos(t)-ide analog: new switch study].

Hepatitis B surface antigen (HBsAg) loss is seldom achieved with nucleos(t)ide analog (NA) therapy in chronic hepatitis B patients but may be enhanced by switching to finite pegylated-interferon (Peg-IFN) alfa-2a. We assessed HBsAg loss with 48- and 96-week Peg-IFN alfa-2a in chronic hepatitis B patients with partial response to a previous NA. Hepatitis B e antigen (HBeAg)-positive patients who achieved HBeAg loss and hepatitis B virus DNA < 200 IU/mL with previous adefovir, lamivudine or entecavir treatment were randomized 1:1 to receive Peg-IFN alfa-2a for 48 ( = 153) or 96 weeks ( = 150).

causes most of aspergillosis in clinic and comprehensive function analysis of its key protein would promote anti-aspergillosis. In a previous study, we speculated actin depolymerizing factor cofilin might be essential for viability and found its overexpression upregulated oxidative response and cell wall polysaccharide synthesis of this pathogen. Here, we constructed a conditional mutant to determine the essential role of cofilin.

Development and validation of a radiomics signature for clinically significant portal hypertension in cirrhosis (CHESS1701): a prospective multicenter study.

Clinically significant portal hypertension (CSPH) is associated with an incremental risk of esophageal varices and overt clinical decompensations. However, hepatic venous pressure gradient (HVPG) measurement, the gold standard for defining CSPH (HVPG≥10 mm Hg) is invasive and therefore not suitable for routine clinical practice. This study aims to develop and validate a radiomics-based model as a noninvasive method for accurate detection of CSPH in cirrhosis.

Hepatitis B Virus-Upregulated LNC-HUR1 Promotes Cell Proliferation and Tumorigenesis by Blocking p53 Activity.

Recent studies have indicated that a number of long noncoding RNAs (lncRNAs) are dysregulated in hepatocellular carcinoma, while their aberrant expressions are associated with tumorigenesis and poor prognosis. To identify hepatitis B virus (HBV)-related lncRNAs, we used RNA deep sequencing to quantify the abundances of lncRNAs in HepG2 cells and HBV transgenic HepG2-4D14 cells. Here, we demonstrate that lnc-HUR1 is significantly upregulated in HepG2-4D14 cells.

A systems pharmacology-oriented discovery of a new therapeutic use of the TCM formula Liuweiwuling for liver failure.
