Insights

Aging and cancer are linked through molecular pathways. This review focuses on Sirtuins 2-7, exploring their emerging roles in cancer development beyond the well-studied Sirtuin 1.

Area of Science:

  • Molecular biology
  • Gerontology
  • Oncology

Background:

  • Aging is the primary risk factor for cancer, indicating shared molecular pathways.
  • Sirtuins (Sirt1-7) are key regulators of cellular processes implicated in aging and cancer.
  • While Sirtuin 1's role in cancer is documented, the functions of Sirtuins 2-7 remain less understood.

Purpose of the Study:

  • To review the emerging roles of Sirtuins 2-7 in carcinogenesis.
  • To highlight the potential of Sirtuins 2-7 as molecular links between aging and cancer.

Main Methods:

  • Literature review of recent studies on Sirtuins 2-7 and cancer.
  • Analysis of Sirtuin involvement in cellular pathways relevant to tumorigenesis.

Main Results:

  • Sirtuins 2-7 modulate critical cellular pathways including DNA repair, metabolism, and proliferation.
  • Evidence suggests Sirtuins 2-7 can act as either tumor suppressors or promoters depending on context.
  • These sirtuins represent a significant, yet understudied, area in aging and cancer research.

Conclusions:

  • Sirtuins 2-7 play crucial, context-dependent roles in cancer development.
  • Further research into Sirtuins 2-7 is essential for understanding the aging-cancer axis.

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.

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,...
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...

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...
