Summary
The long non-coding RNA LINC00665 and microRNA miR-132-5p are elevated in pediatric epilepsy. Their interaction suppresses neuroinflammation by targeting MAPK3, offering potential therapeutic targets.
Area of Science:
- Neuroscience
- Molecular Biology
- Immunology
Background:
- Epilepsy is associated with neuroinflammation.
- MicroRNAs play crucial roles in regulating cellular processes, including inflammation.
Purpose of the Study:
- To investigate the role of miR-132-5p in the inflammatory response in epilepsy.
- To explore the relationship between LINC00665 and miR-132-5p in epilepsy.
Main Methods:
- Quantitative PCR (q-PCR) to measure gene expression.
- Enzyme-linked immunosorbent assay (ELISA) for cytokine detection.
- Western blot (WB) for protein analysis.
- Dual luciferase assay to confirm targeting interactions.
Main Results:
- LINC00665 and miR-132-5p expression were significantly higher in children with epilepsy.
- Inhibition of miR-132-5p in epilepsy cell models increased LINC00665 and miR-132-5p levels while decreasing inflammatory markers (TNF-α, IL-1β, IL-6) and NLRP3/MAPK3 proteins.
- Dual luciferase assay confirmed LINC00665 targets miR-132-5p.
Conclusions:
- LINC00665 and miR-132-5p are upregulated in pediatric epilepsy.
- The LINC00665/miR-132-5p axis attenuates inflammatory responses in epileptic cells, potentially by targeting MAPK3.

01:07MAPK Signaling Cascades
5.0K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

01:19Interactions Between Signaling Pathways
6.2K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
