Summary
Aging impacts tissue repair and increases cancer risk. This review explores how sirtuins, key aging regulators, influence adult stem cell self-renewal in both normal tissue maintenance and cancer development.
Area of Science:
- Gerontology and Cancer Biology
- Stem Cell Biology and Molecular Aging
Background:
- Aging is a degenerative process linked to impaired tissue maintenance and heightened disease susceptibility, including cancer.
- Adult stem cells (ASCs) are crucial for lifelong tissue repair, but their function declines with age.
- Dysregulated ASC self-renewal is implicated in both aging-related tissue dysfunction and cancer stem cell (CSC)-driven tumorigenesis.
Purpose of the Study:
- To review the emerging evidence connecting sirtuins to ASC self-renewal.
- To elucidate the role of sirtuins in regulating normal tissue maintenance and tumorigenesis.
- To explore the dual role of sirtuins in both aging and cancer stem cell biology.
Main Methods:
- Literature review of studies on aging, stem cells, and sirtuins.
- Analysis of genetic and molecular pathways linking sirtuins to stem cell regulation.
- Synthesis of evidence from mammalian models and human studies.
Main Results:
- Sirtuins are evolutionarily conserved regulators implicated in aging processes.
- Evidence suggests sirtuins modulate ASC self-renewal, affecting tissue maintenance.
- Aberrant sirtuin activity may promote CSC self-renewal, contributing to cancer.
Conclusions:
- Sirtuins represent a critical link between aging pathways and stem cell behavior.
- Targeting sirtuins may offer therapeutic strategies for age-related diseases and cancer.
- Further research into sirtuin-stem cell interactions is vital for understanding aging and cancer.

01:12Loss of Tumor Suppressor Gene Functions
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

03:03mTOR 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.

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...
02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
01:05Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
