Summary
Circular RNAs (circRNAs) show altered expression in Juvenile Myoclonic Epilepsy (JME). Specific circRNAs, hsa_circ_0002010 and hsa_circ_0000143, were upregulated, while hsa_circ_0000249 was downregulated in JME patients, suggesting their role in the disorder.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Juvenile Myoclonic Epilepsy (JME) is a common idiopathic generalized epilepsy syndrome with unclear molecular underpinnings.
- Circular RNAs (circRNAs), stable non-coding RNAs, play regulatory roles and are increasingly implicated in neurological disorders.
Purpose of the Study:
- To investigate the association between specific circRNAs (hsa_circ_0000218, hsa_circ_0000229, hsa_circ_0000249, hsa_circ_0002010, and hsa_circ_0000143) and Juvenile Myoclonic Epilepsy (JME).
Main Methods:
- Total RNA was extracted from peripheral blood of 41 JME patients and 41 healthy controls.
- Quantitative real-time PCR was performed after RNase R treatment to analyze circRNA expression levels.
Main Results:
- hsa_circ_0002010 and hsa_circ_0000143 expression were significantly upregulated in JME patients compared to controls (p < 0.001).
- hsa_circ_0000249 expression was significantly downregulated in JME patients (p < 0.001).
- hsa_circ_0002010 and hsa_circ_0000249 showed associations with drug resistance in JME, with differential expression patterns observed in sex-specific analyses.
Conclusions:
- Specific circRNAs are differentially expressed in Juvenile Myoclonic Epilepsy patients.
- These findings suggest a potential role for circRNAs in JME pathogenesis and may guide future research into their diagnostic or therapeutic relevance.

01:24Epilepsy and Seizures: Overview
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...

01:22Epilepsy ll: Types
Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.
02:24Regulation of Expression Occurs at Multiple Steps
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

01:23Regulation of Expression at Multiple Steps
The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the addition of a...
01:13Formation of Muscle Fibers from Myoblasts
De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers.
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription factors...
