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 ends...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
Cirrhosis I: Introduction01:23

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...

Area of Science:

  • Hepatology
  • Molecular Biology
  • Genetics

Background:

  • Cholangiopathies encompass diverse diseases affecting bile duct cells, stemming from various causes like genetic, neoplastic, immune, infectious, vascular, and drug-induced factors.
  • MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.
  • miRNAs are implicated in pathophysiological processes across multiple organs and cell types, suggesting their potential in disease mechanisms.

Purpose of the Study:

  • To review the current knowledge on the role of miRNAs in the development and progression of cholangiopathies.
  • To highlight key findings in the field of miRNA research related to bile duct diseases.
  • To explore the potential of miRNAs as diagnostic and therapeutic targets in hepatology.

Main Methods:

  • Literature review of scientific articles and research papers.
  • Analysis of studies investigating the involvement of miRNAs in cholangiocyte function and disease.
  • Synthesis of findings related to miRNA expression and function in various cholangiopathies.

Main Results:

  • miRNAs are significantly involved in the pathogenesis of cholangiopathies, influencing cholangiocyte proliferation, regression, and transformation.
  • Specific miRNAs have been identified as potential biomarkers for early diagnosis of certain cholangiopathies.
  • miRNA-based therapeutic strategies are emerging as a promising avenue for treating bile duct diseases.

Conclusions:

  • MicroRNAs are critical regulators in the development and progression of cholangiopathies.
