Summary
Understanding ageing reveals interventions to extend healthy lifespan. Research suggests a finite capacity for detoxification and recycling limits life, offering new therapeutic targets for age-related diseases.
Area of Science:
- Gerontology and molecular biology.
- Cellular and organismal ageing research.
Background:
- Ageing involves progressive failure of defence and repair mechanisms, leading to frailty and loss of homeostasis.
- Significant advancements in understanding ageing mechanisms have occurred over the last decade.
- Studies on natural mutants and genetic interventions reveal the malleability of the ageing process.
Purpose of the Study:
- To explore the mechanisms underlying ageing and identify potential interventions.
- To investigate the 'green theory' of ageing and its implications for lifespan.
Main Methods:
- Studying natural mutants that exhibit accelerated ageing phenotypes.
- Identifying mutations in various species that confer extended healthy lifespans.
- Analyzing data to formulate and test the 'green theory' of ageing.
Main Results:
- Mutations can significantly delay ageing and associated conditions, indicating a malleable ageing process.
- The 'green theory' of ageing proposes detoxification and recycling capacity as a key lifespan determinant.
- Experimental approaches and interventions targeting these processes are being developed.
Conclusions:
- The ageing process is highly malleable, with potential for interventions to extend healthy lifespan.
- The 'green theory' provides a novel mechanistic framework for understanding lifespan limits.
- Targeting detoxification and recycling pathways offers promising strategies for increasing healthspan.

01:26Aging
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...

01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
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,...
01:22iPS Cell Differentiation
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
01:30Development of Human Microbiota
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
01:29Somatic to iPS Cell Reprogramming
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012 for this...
