Abstract:
Classically, aging has been defined as a general degeneration process that leads to the loss of corporal function. The loss of function caused by degeneration limits the maximum lifespan of all organisms and is linked to disease and cancer. Nevertheless, the molecular mechanisms behind aging and their connection to cancer are not well understood. NAD-dependent protein deacetylase enzymes, sirtuins, are emerging as a novel molecular link between aging and cancer due to their specific role in cell cycle regulation, antistress response and cell survival. This article reviews the contribution of sirtuins and environmental factors to ontogenic development, senescence and cancer.
Insights
Aging, a process of degeneration, limits lifespan and is linked to cancer. Sirtuins, NAD-dependent enzymes, are key molecular links between aging and cancer, influencing cell regulation and survival.
Area of Science:
- Molecular Biology
- Gerontology
- Oncology
Background:
- Aging is characterized by functional decline, impacting lifespan and increasing disease/cancer risk.
- The molecular underpinnings of aging and its relationship with cancer remain incompletely understood.
- Sirtuins, a class of NAD-dependent protein deacetylases, are implicated in fundamental cellular processes.
Purpose of the Study:
- To review the role of sirtuins in the molecular mechanisms linking aging and cancer.
- To explore the contribution of sirtuins and environmental factors to aging, senescence, and cancer development.
- To highlight sirtuins as a potential therapeutic target connecting aging and cancer biology.
Main Methods:
- Literature review of studies on sirtuins, aging, and cancer.
- Analysis of sirtuin involvement in cell cycle regulation, stress response, and cell survival.
- Examination of environmental factors influencing aging and cancer pathways.
Main Results:
- Sirtuins play a critical role in regulating cell cycle, stress responses, and cell survival, processes central to aging and cancer.
- Evidence suggests sirtuins act as a molecular bridge connecting the aging process with cancer development.
- Environmental factors interact with sirtuin pathways, influencing senescence and oncogenesis.
Conclusions:
- Sirtuins represent a novel molecular link between aging and cancer.
- Understanding sirtuin function is crucial for deciphering the aging-cancer connection.
- Targeting sirtuins may offer therapeutic strategies for age-related diseases and cancer.
