Summary
Physical activity induces beneficial adaptations via molecular pathways, including microRNAs (miRNAs). These small RNA molecules regulate gene expression and may serve as biomarkers for exercise adaptation and injury prevention.
Area of Science:
- Exercise physiology and molecular biology
- Genetics and epigenetics
- Biochemistry and bioinformatics
Background:
- Physical activity drives crucial adaptations for lifelong health.
- Molecular mechanisms of exercise benefits are still being uncovered.
- MicroRNAs (miRNAs) are key regulators of gene expression.
Approach:
- This review examines exercise-induced changes in miRNA activity.
- Focus on miRNAs in the heart, skeletal muscle, and circulation.
- Analysis of miRNAs as indicators of exercise adaptation.
Key Points:
- Exercise alters miRNA expression in key tissues and circulation.
- miRNAs are small, noncoding RNAs regulating gene expression.
- Specific miRNAs are linked to exercise-induced adaptations.
Conclusions:
- Altered miRNA profiles reflect adaptation to physical activity.
- miRNAs show potential for monitoring exercise status and preventing injuries.
- Further research into miRNA function can optimize exercise interventions.

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
