Summary
MicroRNAs (miRNAs) are key regulators of cellular senescence, a state of irreversible cell growth arrest. Dysregulation of miRNA-controlled senescence is implicated in age-related diseases like cancer.
Area of Science:
- Molecular Biology
- Cell Biology
- Gerontology
Background:
- Cellular senescence, a state of stable growth arrest, was initially observed in vitro.
- Recent evidence confirms senescence occurs in vivo and contributes to disease.
- Understanding senescence regulatory mechanisms has rapidly advanced.
Purpose of the Study:
- To review the role of microRNAs (miRNAs) in modulating cellular senescence.
- To examine miRNA influence on senescence-regulatory proteins.
- To discuss the link between miRNA-governed senescence and age-associated diseases.
Main Methods:
- Literature review of recent reports on miRNAs and cellular senescence.
- Analysis of miRNA interactions with target mRNAs.
- Examination of miRNA effects on senescence-associated gene expression.
Main Results:
- MicroRNAs (miRNAs) are identified as critical regulators of cellular senescence.
- miRNAs influence specific proteins involved in senescence pathways.
- Dysregulation of miRNA-mediated senescence is linked to disease pathogenesis.
Conclusions:
- MicroRNAs play a pivotal role in controlling cellular senescence.
- Aberrant miRNA regulation of senescence contributes to age-related pathologies, including cancer.

01:23Regulation of Expression at Multiple Steps
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 addition of a...
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...

02:15Replicative Cell Senescence
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...

02:23Master Transcription Regulators
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...
