Summary
Circular RNAs (circRNAs) are versatile molecules with emerging roles in cellular functions. These non-coding RNAs can be translated into peptides, impacting various diseases and offering potential as biomarkers.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- Circular RNAs (circRNAs) are covalently closed, single-stranded non-coding RNAs found across diverse organisms.
- They participate in biological processes by acting as miRNA decoys, transcriptional modulators, and interacting with RNA-binding proteins.
Purpose of the Study:
- To explore the emerging roles of circRNAs in cellular physiology and disease.
- To highlight the translational potential of circRNAs and their regulatory mechanisms.
- To underscore the significance of circRNAs as potential diagnostic biomarkers and therapeutic targets.
Main Methods:
- Literature review of recent studies on circRNA biology and function.
- Analysis of proposed mechanisms for circRNA translation, including IRES-driven and m6A-mediated pathways.
- Examination of circRNA expression patterns in various diseases.
Main Results:
- Recent findings indicate that certain cytoplasmic circRNAs can be translated into peptides.
- Potential translation mechanisms include internal ribosome entry site (IRES)-driven and m6A-mediated cap-independent translation.
- CircRNAs exhibit unique expression profiles in multiple diseases.
Conclusions:
- CircRNAs possess a diverse regulatory role in biological processes, particularly in disease pathogenesis.
- The translational capacity of circRNAs adds a new dimension to their functional significance.
- Unique expression patterns suggest circRNAs are promising candidates for diagnostic biomarkers and therapeutic interventions.

Translational Regulation
91
Translational regulation in prokaryotes ensures efficient protein synthesis by controlling ribosome access to mRNA. This regulation is mediated by secondary RNA structures, including translational riboswitches, RNA thermometers, and small RNAs (sRNAs), which respond to intracellular and environmental signals to modulate gene expression.Translational RiboswitchesRiboswitches in the leader region of mRNAs can regulate translation by altering the accessibility of the Shine-Dalgarno (SD) sequence,...

Regulation of Expression at Multiple Steps
994
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...

Regulation of Expression Occurs at Multiple Steps
23.2K
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...

Types of RNA
64.8K
Overview
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 the regulation of 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.

lncRNA - Long Non-coding RNAs
8.9K
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...

Transcriptional Regulation: Riboswitches
113
Riboswitches are RNA elements that regulate gene expression by altering their secondary structures in response to specific effector molecules. These elements, located in the leader regions of certain mRNAs, act as transcriptional regulators by toggling between alternative conformations to control downstream gene expression. Riboswitch-mediated regulation is a precise mechanism for modulating biosynthetic pathways, as exemplified by the riboflavin biosynthesis pathway in Bacillus...
