Insights

MicroRNAs (miRNAs) are key regulators of gene expression. This review covers their role in liver diseases, highlighting their potential as diagnostic biomarkers and therapeutic targets.

Area of Science:

  • Molecular Biology
  • Genetics
  • Hepatology

Background:

  • MicroRNAs (miRNAs) are short non-coding RNAs regulating gene expression post-transcriptionally.
  • miRNAs play crucial roles in cellular processes like differentiation, proliferation, and apoptosis.
  • Dysregulated miRNAs are implicated in various pathophysiological conditions, particularly liver diseases.

Purpose of the Study:

  • To review recent advances in identifying deregulated miRNAs in liver diseases.
  • To critically assess the role of miRNAs as biomarkers and therapeutic targets in liver pathobiology.
  • To highlight emerging techniques and clinical trials for miRNA-based therapies.

Main Methods:

  • Literature review of recent studies on miRNA deregulation in liver diseases.
  • Analysis of miRNA roles in obesity, hepatitis, steatohepatitis, cirrhosis, and hepatocellular carcinoma.
  • Examination of preclinical and clinical trials for miRNA-based interventions.

Main Results:

  • Identification of specific miRNAs deregulated across a spectrum of liver diseases.
  • Evidence supporting the utility of miRNAs as biomarkers for diagnosis and prognosis.
  • Demonstration of therapeutic potential for miRNA modulation in preclinical models.

Conclusions:

  • miRNAs are pivotal in liver pathobiology and represent promising diagnostic and therapeutic targets.
  • Further research and clinical trials are essential to translate miRNA findings into effective liver disease treatments.
  • Emerging techniques offer new avenues for restoring miRNA homeostasis in liver disorders.

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 ends...

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...

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...
