Insights

MicroRNAs (miRNAs) regulate cellular senescence, a key factor in aging and disease. This review explores how miRNAs impact senescence pathways, offering insights into therapeutic strategies for age-related disorders.

Area of Science:

  • Cellular and Molecular Biology
  • Aging Research
  • Epigenetics

Background:

  • Cellular senescence is a state of stable cell cycle arrest, crucial in development and disease.
  • Senescence is triggered by various stressors and linked to aging and age-related disorders.
  • Therapeutic elimination of senescent cells shows promise for healthy aging.

Purpose of the Study:

  • To review the regulatory role of microRNAs (miRNAs) in cellular senescence.
  • To elucidate how miRNAs modulate key senescence pathways, including p16, p53, SASP, and calcium signaling.
  • To provide a comprehensive understanding of miRNA-mediated senescence control.

Main Methods:

  • Literature review focusing on miRNA involvement in senescence.
  • Analysis of molecular mechanisms underlying miRNA regulation of senescence pathways.
  • Synthesis of current knowledge on miRNAs, senescence, and related signaling.

Main Results:

  • miRNAs are critical regulators of senescence at transcriptional and post-transcriptional levels.
  • miRNAs influence major senescence pathways: p16, p53, senescence-associated secretory phenotype (SASP), and calcium signaling.
  • Dysregulation of miRNA-senescence interactions contributes to aging and disease.

Conclusions:

  • miRNAs play a significant role in orchestrating cellular senescence.
  • Understanding miRNA-senescence interplay is vital for developing novel therapeutic interventions for aging and related diseases.
  • Targeting miRNAs offers a promising avenue for modulating senescence and improving healthspan.

MicroRNAs

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 the pre-miRNA...

Replicative Cell Senescence02:15

Replicative 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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Regulation of Expression at Multiple Steps01:23

Regulation 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...

Regulation of Expression Occurs at Multiple Steps02:24

Regulation 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...
