Associations of Wnt5a expression with liver injury in chronic hepatitis B virus infection.

Background: Aberrant Wnt5a expression contributes to immunity, inflammation and tissue damage. However, it remains unknown whether Wnt5a is associated with liver injury in chronic hepatitis B virus (HBV) infection. We aimed to explore the potential role of Wnt5a expression in liver injury caused by chronic HBV infection.

Noncanonical Wnt5a/JNK Signaling Contributes to the Development of D-Gal/LPS-Induced Acute Liver Failure.

Acute liver failure (ALF) is a deadly clinical disorder with few effective treatments and unclear pathogenesis. In our previous study, we demonstrated that aberrant Wnt5a expression was involved in acute-on-chronic liver failure. However, the role of Wnt5a in ALF is unknown.

Increased BATF expression is associated with the severity of liver damage in patients with chronic hepatitis B.

T helper (Th) 17 cells have a critical role in the pathogenesis of chronic hepatitis B virus (HBV) infection, and basic leucine zipper transcription factor, ATF-like (BATF) is a newly identified transcriptional factor regulating the differentiation of Th17 cells. However, its precise role in patients with chronic hepatitis B remains unclear. Sixty chronic hepatitis B (CHB) patients, twenty-two acute-on-chronic hepatitis B liver failure (ACHBLF) patients and seventeen healthy controls were included in our study.

High promoter methylation levels of glutathione-S-transferase M3 predict poor prognosis of acute-on-chronic hepatitis B liver failure.

Aim: This study aimed to evaluate the prognostic value of glutathione-S-transferase M3 (GSTM3) gene promoter methylation in patients with acute-on-chronic hepatitis B liver failure (ACHBLF).

Methods: A total of 119 patients with ACHBLF, 60 patients with chronic hepatitis B and 30 healthy controls were enrolled. We used a quantitative methylation detection technique, MethyLight, to examine the methylation levels of GSTM3 in peripheral blood mononuclear cells.

A noninvasive model to predict liver histology in HBeAg-positive chronic hepatitis B with alanine aminotransferase ≤ 2upper limit of normal.

Background And Aim: Liver biopsy remains the gold standard to evaluate liver histology. However, it has several limitations. This study aims to construct a noninvasive model to predict liver histology for commencing antiviral therapy in HBeAg-positive chronic hepatitis B (CHB) with aminotransferase (ALT) ≤ 2 upper limit of normal (ULN).

Methylation of the Glutathione-S-Transferase P1 Gene Promoter Is Associated with Oxidative Stress in Patients with Chronic Hepatitis B.

Glutathione-S-transferase P1 (GSTP1) and glutathione-S-transferase M3 (GSTM3) catalyze the glutathione-related clearance of xenobiotics. The methylation of these gene promoters was associated with oxidative stress that induced liver damage. This study aims to explore the relationship among GSTP1 and GSTM3 methylation, DNA methyltransferases (DNMTs) expression, and oxidative stress in patients with chronic hepatitis B (CHB).

Promoter methylation status and expression of PPAR-γ gene are associated with prognosis of acute-on-chronic hepatitis B liver failure.

Background: Peroxisome proliferator-activated receptor gamma (PPAR-γ) has been demonstrated to be involved in anti-inflammatory reactions, but its role in acute-on-chronic hepatitis B liver failure (ACHBLF) is unclear. Therefore, DNA methylation patterns and expression level of PPAR-γ gene were detected in peripheral blood mononuclear cells (PBMCs) from 81 patients with ACHBLF, 50 patients with chronic hepatitis B (CHB), and 30 healthy controls, and the possible role of PPAR-γ in ACHBLF was analyzed.

Results: We found that aberrant PPAR-γ promoter methylation was attenuated in ACHBLF patients compared with CHB patients and was responsible for the elevated PPAR-γ expression level, which was negatively correlated with total bilirubin and international normalized ratio.

Methylation of tissue factor pathway inhibitor 2 as a prognostic biomarker for hepatocellular carcinoma after hepatectomy.

Background And Aim: Methylation of tissue factor pathway inhibitor 2 (TFPI2) gene has been detected in hepatocellular carcinoma (HCC). However, the clinicopathologcial significance and prognostic value of TFPI2 methylation in HCC remains largely unknown. This study aimed to investigate the prognostic value of TFPI2 methylation in HCC after hepatectomy.

Overexpression of serum sST2 is associated with poor prognosis in acute-on-chronic hepatitis B liver failure.

Background And Objective: Interleukin-33 (IL-33) and soluble ST2 (sST2) have been demonstrated to be involved in liver injury. The present study aims to evaluate serum IL-33 and sST2 level in acute-on-chronic hepatitis B liver failure (ACHBLF) and determine their predictive value for prognosis.

Methods: Serum IL-33 and sST2 level in patients with ACHBLF, chronic hepatitis B (CHB) and healthy controls (HCs) were determined by enzyme-linked immunosorbent assay (ELISA).

Serum wnt5a is a predictor for the prognosis of acute on chronic hepatitis B liver failure.

Objectives: To find a biomarker to predict the prognosis of acute on chronic hepatitis B liver failure (ACHBLF).

Methods: Expression gene profiles in wnt pathway were determined in serum from 63 patients with ACHBLF, 60 patients with chronic hepatitis B (CHB) and 30 healthy controls (HCs).

Results: Serum wnt5a concentration of 1.

MT1M and MT1G promoter methylation as biomarkers for hepatocellular carcinoma.

Aim: To investigate the potential of promoter methylation of two tumor suppressor genes (TSGs) as biomarkers for hepatocellular carcinoma (HCC).

Methods: A total of 189 subjects were included in this retrospective cohort, which contained 121 HCC patients without any history of curative treatment, 37 patients with chronic hepatitis B (CHB), and 31 normal controls (NCs). DNA samples were extracted from 400 μL of serum of each subject and then modified using bisulfite treatment.

Aberrant DNA methylation of G-protein-coupled bile acid receptor Gpbar1 (TGR5) is a potential biomarker for hepatitis B Virus associated hepatocellular carcinoma.

Background: G-protein-coupled bile acid receptor Gpbar1 (TGR5) is a newly identified liver tumor suppressor in carcinogenesis. This present study was therefore to determine the potential value of serum TGR5 promoter methylation in identifying hepatocellular carcinoma (HCC) from chronic hepatitis B (CHB) patients.

Methods: The circulating cell-free DNA (cfDNA) was extracted from a retrospective dataset including 160 HCC, 88 CHB and 45 healthy controls (HCs).
