Insights

Alcoholic liver disease (ALD) involves liver damage and inflammation, with alcohol altering microRNA (miRNA) profiles. Research explores miRNA roles in ALD pathogenesis, potential as biomarkers, and future miRNA-based therapies.

Area of Science:

  • Hepatology
  • Molecular Biology
  • Biochemistry

Background:

  • Alcoholic liver disease (ALD) is marked by liver cell damage, inflammation, and increased gut permeability.
  • Alcohol consumption alters microRNA (miRNA) expression in the liver and circulation of ALD patients.
  • Dysregulated miRNAs impact genes involved in inflammation, lipid metabolism, and cancer development in ALD.

Purpose of the Study:

  • To review recent findings on miRNA expression and function in ALD pathogenesis.
  • To discuss the significance of cell-specific and circulating extracellular miRNAs as potential ALD biomarkers.
  • To evaluate the therapeutic potential of miRNA-based strategies for ALD.

Main Methods:

  • Literature review of studies on miRNA expression and function in ALD.
  • Analysis of research on alcohol's impact on miRNA profiles.
  • Examination of studies investigating miRNA biomarkers and therapeutic applications.

Main Results:

  • Alcohol significantly affects specific miRNAs, leading to abnormal profiles in ALD.
  • Altered miRNAs regulate key pathways implicated in ALD, including inflammation, lipid metabolism, and oncogenesis.
  • Extracellular miRNAs show promise as non-invasive biomarkers for ALD detection and monitoring.

Conclusions:

  • MicroRNAs play a critical role in the molecular mechanisms underlying ALD.
  • miRNAs, particularly circulating ones, represent promising biomarkers for ALD.
  • miRNA-targeted therapies offer a potential new avenue for ALD treatment.

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

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...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Chronic Pancreatitis II: Pathophysiology

Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
