Abstract

Insights

Novel therapies for alcoholic hepatitis (AH) may target TNF superfamily receptors. Research identified Fn14 as exclusively upregulated in AH patients, correlating with mortality and disease severity, suggesting it as a potential therapeutic target.

Area of Science:

  • Hepatology
  • Molecular Biology
  • Translational Medicine

Background:

  • Alcoholic hepatitis (AH) is a severe liver condition requiring new therapeutic strategies.
  • Identifying therapeutic targets is challenging due to a lack of advanced AH animal models.
  • Transcriptome analysis in AH patients can reveal novel molecular targets.

Purpose of the Study:

  • To identify new molecular targets for alcoholic hepatitis therapy.
  • To investigate the role of TNF superfamily receptors in AH pathogenesis.
  • To determine if Fn14 is a specific biomarker and therapeutic target for AH.

Main Methods:

  • DNA microarray analysis of hepatic gene expression in AH patients and controls.
  • Gene set enrichment analysis to identify regulated pathways.
  • Quantitative PCR, immunohistochemistry, and western blotting in patient cohorts and animal models.

Main Results:

  • Overexpression of several TNF superfamily receptors, but not ligands, was observed in AH.
  • Fn14 was exclusively upregulated in AH compared to other liver diseases.
  • Fn14 expression correlated with 90-day mortality and portal hypertension severity in AH patients.

Conclusions:

  • Translational research identified TNF superfamily receptors as overexpressed in AH.
  • Fn14 is selectively upregulated in AH patients and could be a potential therapeutic target.
  • Further investigation of TNF superfamily receptors may lead to novel AH treatments.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
