Summary
Researchers discovered a novel class of circular RNAs derived from introns, termed circular intronic RNAs (ciRNAs). These ciRNAs can potentially boost the transcription of the genes from which they originate.
Area of Science:
- Molecular Biology
- Gene Regulation
- RNA Biology
Background:
- Circular RNAs (circRNAs) are increasingly recognized for their diverse biological roles.
- Intronic regions of the genome were traditionally considered non-coding and largely functional.
Purpose of the Study:
- To identify and characterize novel types of circular RNAs.
- To investigate the function of intron-derived circular RNAs in gene expression.
Main Methods:
- Bioinformatic analysis of RNA sequencing data.
- Molecular cloning and validation of circular RNA candidates.
- Quantitative PCR and other molecular assays to assess gene transcription.
Main Results:
- Identification of a new class of circular RNAs originating from introns (ciRNAs).
- Demonstration that ciRNAs are relatively stable molecules.
- Evidence that ciRNAs can enhance the transcription of their cognate host genes.
Conclusions:
- Circular intronic RNAs (ciRNAs) represent a newly discovered class of regulatory RNAs.
- ciRNAs possess the capacity to positively regulate gene transcription.
- These findings expand our understanding of RNA-based gene regulation and the functional potential of introns.

02:02Cis-regulatory Sequences
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

02:04Co-activators and Co-repressors
Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

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...
