[Research advance of microRNA in the pathogenesis of chronic rhinosinusitis]

Insights

MicroRNAs (miRNAs) are implicated in chronic rhinosinusitis (CRS) pathogenesis. This review explores miRNA expression and their role in CRS, aiming to clarify the disease

Area of Science:

  • Otorhinolaryngology
  • Head and Neck Surgery
  • Molecular Biology

Background:

  • Chronic rhinosinusitis (CRS) is a prevalent inflammatory condition affecting the nasal sinuses.
  • The exact causes and mechanisms underlying CRS development remain incompletely understood.
  • MicroRNAs (miRNAs) have emerged as potential regulators of gene expression relevant to CRS.

Purpose of the Study:

  • To review and summarize the current understanding of miRNA expression in chronic rhinosinusitis.
  • To investigate the specific roles of various miRNAs in the pathogenesis of CRS.
  • To provide insights that may help elucidate the underlying mechanisms of CRS.

Main Methods:

  • Literature review of studies investigating miRNA expression in chronic rhinosinusitis.
  • Analysis of existing research on the functional roles of miRNAs in CRS.
  • Synthesis of findings to present a comprehensive overview.

Main Results:

  • Evidence suggests altered expression of specific miRNAs in the sinonasal mucosa of CRS patients.
  • MiRNAs are involved in regulating key cellular processes implicated in CRS, such as inflammation and immune response.
  • Specific miRNA profiles may correlate with different subtypes or severity of CRS.

Conclusions:

  • MicroRNAs play a significant role in the pathogenesis of chronic rhinosinusitis.
  • Understanding miRNA dysregulation offers potential therapeutic targets for CRS.
  • Further research into miRNA-mediated pathways is crucial for advancing CRS treatment.

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...

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Asthma: Pathogenesis and Management01:20

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.

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

COPD: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
