Insights

Plasma microRNAs (miRNAs) can predict atherosclerosis in hyperhomocysteinemia patients. Specifically, miR-217 shows diagnostic value for atherosclerosis, aiding in predicting disease progression.

Area of Science:

  • Cardiovascular Research
  • Molecular Biology
  • Biomarker Discovery

Background:

  • Hyperhomocysteinemia (Hhcy) is linked to atherosclerosis.
  • Plasma microRNAs (miRNAs) are potential biomarkers for various diseases.
  • Specific miRNAs regulate genes involved in atherosclerosis development.

Purpose of the Study:

  • To investigate if plasma atherosclerosis-associated miRNAs can predict atherosclerosis in Hhcy patients.
  • To identify specific miRNAs with diagnostic potential for Hhcy-complicated atherosclerosis.

Main Methods:

  • Selected six plasma miRNAs (miR-145, miR-155, miR-222, miR-133, miR-217, miR-30) known to be involved in atherosclerosis.
  • Measured miRNA expression levels in plasma from Hhcy patients with and without atherosclerosis.
  • Correlated miRNA expression with homocysteine (Hcy) and lipid parameters.

Main Results:

  • Significant differential expression of five miRNAs (upregulation of miR-133, miR-217; downregulation of miR-145, miR-155, miR-222) was observed.
  • miR-217 was significantly upregulated in Hhcy + Atherosclerosis (ATH) groups compared to controls.
  • miR-217 showed a negative correlation with Hcy and triglycerides and specific expression patterns in ATH patients.

Conclusions:

  • Plasma miR-217 expression is a potential diagnostic biomarker for atherosclerosis in Hhcy patients.
  • miR-217 may effectively predict the progression of atherosclerosis in individuals with Hhcy.
  • Targeting miR-217 could offer therapeutic strategies for Hhcy-associated atherosclerosis.

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

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...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
