Summary
MicroRNAs (miRNAs) are key regulators in the brain, influencing neurological disorders like ischemic stroke. Research highlights their neuroprotective potential and use as biomarkers for stroke treatment.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression, crucial in brain function.
- Dysregulated miRNAs are implicated in neurological disorders, including cerebrovascular diseases.
- Specific miRNAs play roles in ischemic stroke, affecting processes like apoptosis and neuroprotection.
Purpose of the Study:
- To review the emerging role of miRNAs in neuroprotection.
- To focus on specific miRNAs central to ischemic stroke pathology.
- To explore miRNAs as biomarkers and therapeutic targets for stroke.
Main Methods:
- Literature review of studies on miRNAs in neurological disorders and ischemic stroke.
- Analysis of miRNA involvement in signaling pathways relevant to cerebrovascular diseases.
- Discussion of computational tools and systems biology approaches.
Main Results:
- miRNAs regulate gene expression in pathways linked to ischemic stroke, subarachnoid hemorrhage, and vascular dementia.
- Examples include miR-21 (atherosclerosis, anti-apoptosis), miR-497 (neuronal death), and miR-210 (hypoxia).
- Deregulated miRNA expression in stroke offers potential as non-invasive biomarkers; antagomirs show therapeutic promise.
Conclusions:
- miRNAs are significant players in neuroprotection and ischemic stroke.
- Targeting specific miRNAs and utilizing them as biomarkers represent promising avenues for stroke treatment.
- Systems biology aids in understanding miRNA-target interactions in stroke pathology.

01:17Ischemic Heart Disease: Overview
4.0K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

2.3K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

01:30Peripheral Artery Disease I: Introduction
640
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

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)...
