Summary
Enhancer RNAs (eRNAs) are transcribed from noncoding DNA and play crucial roles in gene regulation. Research highlights their emerging importance in brain health and neurological disorders.
Area of Science:
- Genomics and Transcriptomics
- Molecular Biology
- Neuroscience
Background:
- Noncoding DNA is transcribed into noncoding RNAs with regulatory functions.
- Enhancers are key regulatory elements controlling gene expression.
- Enhancer RNAs (eRNAs) are transcribed from active enhancers and influence gene regulation.
Purpose of the Study:
- To review current literature on enhancer RNA (eRNA) biology in the brain.
- To discuss the role of eRNAs in brain health and disease.
- To identify challenges and future research directions for eRNAs in neurological disorders.
Main Methods:
- Literature review of genomics and transcriptomics studies.
- Analysis of enhancer activity and eRNA transcription in the brain.
- Synthesis of findings related to eRNA function in neurological conditions.
Main Results:
- Enhancers are dynamic regulatory elements involved in complex gene networks.
- eRNAs are produced upon enhancer activation and contribute to gene regulation.
- eRNA dysregulation is implicated in various brain disorders, from injury to neurodegeneration.
Conclusions:
- eRNAs play significant roles in activity-driven gene expression in the brain.
- Emerging evidence points to eRNAs involvement in neurological disease pathogenesis.
- Further research is needed to fully elucidate eRNA function and therapeutic potential in brain disorders.

02:39lncRNA - Long Non-coding RNAs
8.6K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

02:41Chromatin Structure Regulates pre-mRNA Processing
7.0K
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.

02:18Alternative RNA Splicing
21.1K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...

02:23RNA Editing
9.0K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

02:36RNA Polymerase II Accessory Proteins
9.2K
Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...

01:20Types of RNA
5.8K
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
