Explore the science of ageing. Learn why we age, the biological processes behind it, and how advancements in research are The evolutionary theory of ageing explains why ageing occurs, giving valuable insight into the mechanisms underlying the complex cellular

PARP1 inhibitors trigger innate immunity via PARP1 trapping-induced DNA damage response Cell cycle arrest in response to a double-stranded break is initially maintained by the DNA damage checkpoint and later by the spindle assembly Why do we age? As I mentioned there are as many theories of aging as there are scientists working on the problem, but most of them can be

If DNA damage and age-related epigenetic changes are linked, a prediction is that increased DNA damage would accelerate the epigenetic clock (Figure 2). DNA repair deficiency can cause premature aging in humans and mice, e.g., XFE progeroid syndrome, caused by mutations in XPF, which encodes the catalytic domain of the DNA repair endonuclease Thirty-five years ago we overthrough this dogma when we found that normal cells do have a limited capacity to divide, and that age changes can occur intracellularly.

After performing the miracles that takes us from conception to birth, and then to sexual maturation and adulthood, natural selection was unable to favor the development of a more elementary mechanism that would simply maintain those earlier miracles forever. The manifestations of this failure are ca How and Why We Age defines the difference between biological and chronological age and then takes a look at how our understanding of aging has changed through history. With the immediacy of the latest scientific discoveries, Dr. Hayflick explains how aging affects every part of the human body. Dr. Hayflick notes that because aging involves virtually every cell in our bodies – a Thirty-five years ago we overthrough this dogma when we found that normal cells do have a limited capacity to divide, and that age changes can occur intracellularly. We also observed that only abnormal or cancer cells are immortal. Normal cells are mortal because telomeres shorten at each division.

Here, we review evidence that DNA damage plays a causal role in aging. We also provide evidence that genotoxic stress is linked to other cellular processes implicated as drivers of aging, including mitochondrial and metabolic dysfunction, altered proteostasis and inflammation. Damage-related and environmental aging Damage-related and environmental aging is related to extrinsic factors. It refers to how our surroundings and lifestyle affect how we age.

Computational and Systems Biology Deep learning linking mechanistic models to single-cell transcriptomics data reveals transcriptional bursting in response to DNA damage Borrowed Time explores scientific discoveries that have shaped our ever-changing conception of aging. Some of these discoveries will be familiar from college biology, such as telomerase and pluripotent stem cells; other experiments may be more recognizable for their resultant fads and pop science, like intermittent fasting. As the global population continues to live longer, it is

The transcription factors TFE3 and TFEB amplify p53 dependent transcriptional programs in response to DNA damage eLife 7:e40856.

DNA damage induces nuclear actin filament assembly by Formin-2 and Spire-1/2 that promotes efficient DNA repair eLife 4:e07735.

Structural characterization of human RPA70N association with a series of DNA damage response proteins reveals versatile protein interaction mechanisms that help to recruit DNA repair proteins to the damage site quickly and efficiently. Why Do We Age? Aging is a complex, multifaceted process influenced by evolutionary biology and cellular mechanisms. Understanding why we age involves exploring both the evolutionary theories and the biological changes that occur over time.

Abstract DNA damage is a critical factor contributing to genetic alterations, directly affecting human health, including developing diseases such as cancer and age-related disorders. DNA repair mechanisms play a pivotal role in safeguarding genetic integrity and preventing the onset of these ailments. Over the past decade, substantial progress and pivotal discoveries Learn about the free radical theory and other biological aging concepts. Discover how modern biology explains the genetic and social effects of aging. The rate at which we age is influenced by daily choices, environment, and targeted interventions that support cellular function. But what exactly drives ageing, and what can we do about it? Let’s explore the latest research and how Pure NMN, used in clinical trials, could be a powerful tool for energy, metabolism, and DNA repair

Ageing is an inevitable part of life, yet the processes behind it are complex and fascinating. Understanding the science of ageing helps us not only grasp why we age but also explore how we can improve health and longevity. By delving into the biological, genetic, and environmental factors that drive ageing, we uncover opportunities to extend healthspan—the years of life Review Article Published: November 2008 DNA damage and ageing: new-age ideas for an age-old problem George A. Garinis, Gijsbertus T.J. van der Horst, Jan Vijg & Jan H.J. Hoeijmakers Nature Cell The initiation of DNA damage checkpoint recovery involves ATM-mediated E3 ubiquitin ligase E6AP phosphorylation which disrupts E6AP-MASTL association and leads to MASTL protein accumulation and cell cycle resumption.

Meet the 12 ‚Hallmarks of Ageing‘ – the cellular processes that drive how we age. From DNA damage to cellular ‚zombies‘, we’re making the science accessible. In the present work, we examine and discuss the above fundamental questions from this perspective. We also systematically analyze senescence and its main driver (DNA damage) for different gestational stages in mouse pregnancy. Using the AnAge dataset, we examine the relationships between gestation period and lifespan in mammals.

In this paper, we investigate the scalability and potentials of DNA storage when a huge amount of data, like all available data from the world, is to be stored. Understanding how DNA damage is found and repaired by enzymes in the cell is of high importance. Zhu et al. propose that the enzyme-DNA recognition process involves charge and electrons’ spin polarization, revealing a possible mechanism for damage detection “from a Finally, we discuss potential interventions against age-related inflammation. In this Review, Gorbunova and colleagues discuss the links between DNA damage, inflammation and ageing.

Finally, we give special attention to non-cell-autonomous DNA damage responses (DDRs), which promote tissue dysfunction and compensatory responses with the aim of re-establishing tissue homeostasis, as the study of these will surely facilitate the identification of the mechanisms underlying the systemic effects of DNA damage in the future.

DNA damage refers to changes or disruptions that occur in the DNA molecule caused by environmental factors or normal processes that happen inside our cells.
