Insights

MicroRNAs are crucial in regulating genes in pulmonary arterial hypertension (PAH). Research highlights specific microRNAs involved in PAH, suggesting potential therapeutic avenues for this vascular disease.

Area of Science:

  • Molecular Biology
  • Cardiovascular Research
  • Gene Regulation

Background:

  • MicroRNAs (miRNAs) are key regulators of gene expression implicated in various diseases, including cancer and cardiovascular conditions.
  • Pulmonary arterial hypertension (PAH) is a vascular disease characterized by increased pulmonary resistance and vessel occlusion.
  • PAH shares common pathways with cancer, involving aberrant proliferation and survival of pulmonary arterial smooth muscle cells (PASMCs).

Purpose of the Study:

  • To review the current understanding of microRNA involvement in pulmonary arterial hypertension (PAH).
  • To highlight recent findings on specific microRNAs and their roles in PAH pathogenesis.
  • To discuss future directions and therapeutic potential of microRNAs in PAH.

Main Methods:

  • Literature review of recent studies on microRNAs in PAH.
  • Analysis of identified microRNAs and their association with PAH pathways.
  • Synthesis of current knowledge and future perspectives.

Main Results:

  • Specific microRNAs, including miR-204 and miR-206, are implicated in PASMC proliferation.
  • Other miRNAs like miR-145, miR-21, and the miR17/92 cluster are linked to the disrupted BMPR2 pathway in PAH.
  • The role of microRNAs in PAH is a rapidly expanding and significant area of research.

Conclusions:

  • MicroRNAs play a critical role in the molecular mechanisms underlying PAH.
  • Further research is needed to translate microRNA knowledge into effective clinical therapies for PAH.
  • MicroRNA-based therapies hold promise but require further development and validation for clinical application.

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme (ECE). Of...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists

Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

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...

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...
