Insights

Circular RNAs (circRNAs) show potential as aging biomarkers due to their stability and age-related accumulation. These molecules may drive aging processes and offer therapeutic targets for age-associated diseases.

Area of Science:

  • Gerontology
  • Molecular Biology
  • Biochemistry

Background:

  • Aging is a major challenge for healthcare systems, necessitating reliable biomarkers for progression assessment.
  • Circular RNAs (circRNAs) are stable, age-accumulating molecules found in biological fluids, making them promising aging biomarkers.
  • Understanding circRNA biogenesis and function is crucial for aging research.

Purpose of the Study:

  • To review current knowledge on circRNA expression and function in aging.
  • To explore the role of circRNAs in aging hallmarks like genomic stability and metabolism.
  • To identify circRNAs as potential epigenetic biomarkers and therapeutic targets for age-related diseases.

Main Methods:

  • Systematic review of scientific databases for circRNA expression data in aging.
  • Analysis of circRNA biogenesis and regulatory mechanisms.
  • Focus on circRNAs involved in aging-related cellular processes.

Main Results:

  • CircRNAs accumulate with age and are differentially expressed across species, including humans.
  • Age-related circRNA accumulation and deregulation may drive aging processes.
  • Specific circRNAs (e.g., circFOXO3, circRNA100783, circPVT1) are linked to aging.

Conclusions:

  • CircRNAs represent a novel class of epigenetic biomarkers for aging.
  • CircRNAs may play a causative role in aging and associated diseases.
  • Targeting circRNAs could offer new therapeutic strategies for age-related conditions.

Types of RNA

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.

RNA Stability01:53

RNA Stability

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Transcriptional Regulation: Riboswitches01:23

Transcriptional Regulation: Riboswitches

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...

Translational Regulation01:29

Translational Regulation

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,...

lncRNA - Long Non-coding RNAs

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...

Circadian Rhythms and Gene Regulation

The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...
