Insights

Molecular ageing involves complex tumor suppressor pathways like p53 and pRB, and telomere maintenance. Modern functional RNA tools offer new ways to understand and potentially intervene in ageing processes for improved quality of life.

Area of Science:

  • Gerontology and Molecular Biology
  • Genomics and Post-genomic Technologies

Background:

  • Ageing is a fundamental biological process with increasing molecular complexity.
  • Tumor suppressor pathways (p53, pRB) and telomere maintenance are key players in ageing.
  • Understanding these mechanisms is crucial for addressing age-related decline.

Purpose of the Study:

  • To review the current understanding of molecular ageing.
  • To explore modern intervention strategies, particularly in culture systems.
  • To highlight the role of emerging functional RNA tools.

Main Methods:

  • Discussion of molecular mechanisms of ageing, including senescence pathways.
  • Review of novel functional RNA tools for genomic analysis.
  • Application of post-genomic technologies for target discovery.

Main Results:

  • Identification of distinct roles for p53, pRB, and telomere pathways in ageing.
  • Demonstration of functional RNA tools' efficacy in decoding the human genome.
  • Potential for discovering gene targets for anti-ageing interventions.

Conclusions:

  • Molecular ageing is intricate, involving multiple genetic and cellular pathways.
  • Functional RNA tools and post-genomic approaches are powerful for ageing research.
  • Interventions targeting identified gene pathways may enhance healthspan, not just lifespan.

Aging01:26

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...
Mitochondria01:37

Mitochondria

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,...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/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...
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 the telomeric...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...
