Abstract

Insights

MicroRNAs (miRs) are key regulators in asthma pathogenesis, impacting gene expression and airway remodeling. Understanding miRs offers potential for developing novel therapeutic strategies for this chronic respiratory condition.

Area of Science:

  • Respiratory Medicine
  • Molecular Biology
  • Genetics

Background:

  • Asthma is a complex chronic inflammatory airway disorder with variable airflow obstruction and bronchial hyper-responsiveness.
  • The precise molecular mechanisms underlying asthma pathogenesis are not fully understood, hindering effective therapeutic development.
  • Recent advancements in identifying microRNAs (miRs) provide new tools to investigate asthma's disease processes.

Purpose of the Study:

  • To review the current understanding of the role and regulation of microRNAs (miRs) in asthma.
  • To explore how miRs contribute to the pathophysiology of asthma.
  • To discuss the potential of miRs in developing novel therapeutic strategies for asthma.

Main Methods:

  • Literature review of current research on microRNAs and asthma.
  • Analysis of studies investigating miR regulation of gene expression in asthma.
  • Synthesis of findings on the role of miRs in asthma pathophysiology and airway remodeling.

Main Results:

  • MicroRNAs (miRs) are identified as key regulatory RNAs with significant roles in numerous biological processes, including asthma.
  • miRs regulate gene expression by controlling messenger RNA translation, influencing multiple signal transduction pathways involved in asthma.
  • miRs are implicated in acute and chronic asthma, as well as airway remodeling, suggesting a fundamental role in the disease.

Conclusions:

  • MicroRNAs (miRs) play a crucial role in the pathophysiology of asthma.
  • Understanding miR regulation in asthma can lead to a fundamental shift in comprehending the disease.
  • miRs hold promise for the development of novel and efficacious therapeutic strategies for asthma.

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...

Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
