MicroRNA in hepatic fibrosis and cirrhosis

Insights

MicroRNAs (miRNAs) play a key role in liver fibrosis and cirrhosis development. This review details how miRNAs regulate hepatic stellate cells in various liver diseases, including viral hepatitis and hepatocellular carcinoma.

Area of Science:

  • Hepatology
  • Molecular Biology
  • Gastroenterology

Background:

  • Hepatic fibrosis results from extracellular matrix imbalance due to chronic liver injury.
  • Hepatic stellate cell activation drives fibrosis progression.
  • Cirrhosis, advanced fibrosis, can lead to hepatocellular carcinoma (HCC).

Purpose of the Study:

  • To review the role of microRNAs (miRNAs) in the pathogenesis of liver fibrosis.
  • To explore miRNA involvement in cirrhosis and HCC onset.
  • To highlight miRNA regulation of hepatic stellate cells in various liver diseases.

Main Methods:

  • Literature review of studies on miRNA function in liver fibrosis.
  • Analysis of miRNA involvement in viral hepatitis, non-alcoholic steatohepatitis, and primary biliary cirrhosis.
  • Focus on miRNA-mediated regulation of hepatic stellate cells.

Main Results:

  • MicroRNAs are implicated in the development of hepatic fibrosis and cirrhosis.
  • miRNAs influence the progression from fibrosis to hepatocellular carcinoma.
  • Specific miRNAs regulate the activation and proliferation of hepatic stellate cells.

Conclusions:

  • MicroRNAs are critical regulators in liver fibrosis and cirrhosis pathogenesis.
  • Targeting miRNA pathways may offer therapeutic strategies for liver diseases.
  • Understanding miRNA roles is essential for preventing HCC development from fibrosis.

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 the pre-miRNA...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...
