Summary
MicroRNAs (miRNAs) regulate biological processes and are implicated in aging. Studies show miRNAs are differentially expressed in aging, targeting aging pathways and coordinating complex networks.
Area of Science:
- Molecular Biology
- Genetics
- Aging Research
Background:
- MicroRNAs (miRNAs) are small RNAs regulating gene expression post-transcriptionally.
- Their network-level function is crucial for complex biological processes.
- Aging is a complex process involving multiple interconnected pathways.
Purpose of the Study:
- To investigate the role of microRNAs in the aging process.
- To understand how miRNAs function at a network level during aging.
- To identify specific miRNAs involved in coordinating aging-associated pathways.
Main Methods:
- Genome-wide miRNA expression profiling.
- Analysis of miRNA targeting of known aging-associated pathways.
- Investigating global trends in miRNA expression over time.
Main Results:
- Many miRNAs exhibit differential expression during aging.
- Target genes of these miRNAs are frequently involved in aging pathways.
- Global patterns of miRNA expression change are observed over time.
- Several miRNAs appear to coordinate multiple aging-related pathways.
Conclusions:
- MicroRNAs play a significant role in regulating aging processes.
- Understanding miRNA networks is key to deciphering aging pathogenesis.
- MicroRNAs connect disparate pathways involved in aging.

01:22MicroRNAs
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 ends...

01:37Mitochondria
Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
01:22PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
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...
