Insights

Circulating microRNA-145 levels are significantly elevated in patients with ischemic stroke compared to healthy individuals. This finding suggests microRNA-145 may serve as a novel biomarker for stroke diagnosis and understanding hemostatic alterations.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cardiovascular Research

Background:

  • Cerebral ischemia, or ischemic stroke, primarily stems from vascular and circulation issues.
  • While protein biomarkers are known, RNA profiles, including microRNAs, are emerging as potential stroke markers.
  • MicroRNA-145 (miR-145) is recognized for its role in vascular smooth muscle cell phenotype, but its expression in ischemic stroke was unexamined.

Purpose of the Study:

  • To investigate the expression levels of circulatory microRNA-145 in patients with ischemic stroke.
  • To determine if microRNA-145 can serve as a biomarker for ischemic stroke.

Main Methods:

  • Real-time quantitative PCR was used to analyze circulatory microRNA-145 expression.
  • The study included 32 ischemic stroke patients and 14 healthy control subjects.

Main Results:

  • Circulatory microRNA-145 expression was significantly higher in ischemic stroke patients compared to healthy controls.
  • The elevated levels indicate that hemostatic mechanisms are impacted by ischemic stroke.

Conclusions:

  • Circulating microRNA-145 shows potential as a diagnostic biomarker for ischemic stroke.
  • Further research is warranted to explore the role of miR-145 in stroke pathophysiology and hemostasis.

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
