Summary
Non-coding RNAs (ncRNAs) are active in the brain and change after cerebral ischemia. Modulating specific microRNAs may offer new therapeutic targets for stroke brain damage.
Area of Science:
- Genomics
- Neuroscience
- Molecular Biology
Background:
- The mammalian genome contains numerous non-coding (nc) RNA genes with largely unknown functions.
- The central nervous system (CNS) exhibits high ncRNA activity, with emerging roles in neurological diseases.
- Cerebral ischemia significantly alters the expression profiles of various ncRNA classes, including microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and piwi-interacting RNAs (piRNAs).
Purpose of the Study:
- To explore the role of ncRNAs in the context of CNS diseases, particularly following cerebral ischemia.
- To highlight the potential of ncRNAs, especially miRNAs, as therapeutic targets for mitigating secondary brain damage after stroke.
Main Methods:
- Review of recent studies investigating ncRNA expression changes in response to cerebral ischemia.
- Analysis of research demonstrating the impact of miRNA modulation on post-ischemic neuronal outcomes.
Main Results:
- Expression profiles of miRNAs, lncRNAs, and piRNAs are rapidly altered by cerebral ischemia.
- Modulation of specific miRNAs can influence neuronal death and plasticity/regeneration after ischemia.
Conclusions:
- ncRNAs play a significant role in the CNS and are dynamically regulated by ischemic events.
- Targeting specific ncRNAs, particularly miRNAs, presents a promising avenue for developing novel therapeutic strategies against stroke-induced brain injury.

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
01:15Ischemic 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.
