BUFFALO, NY — April 16, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 3, on March 12, 2025, titled “DNA methylation entropy is a biomarker for aging.” Researchers Jonathan Chan, Liudmilla Rubbi, and Matteo Pellegrini from the University of California, Los Angeles, led a study that discovered a new way to measure changes in DNA that can help predict a person’s age. This method focuses on how random certain chemical tags on DNA become over time. The team compared this new measurement, called methylation entropy, to existing methods and found it performed just as well—or even better. These findings support the idea that changes in our epigenetic information are closely linked to aging and could offer new tools for studying age-related diseases. The study focused on DNA methylation, a process where chemical marks are added to DNA and help control which genes are turned on or off. Scientists have traditionally measured average methylation levels to estimate biological age using “epigenetic clocks.” This study, however, takes a different approach. The researchers used buccal swabs (cells from inside the cheek) from 100 individuals between ages 7 and 84 and applied targeted bisulfite sequencing techniques to measure methylation entropy across 3,000 regions of the genome. Entropy in this context reflects how disordered or varied the methylation patterns are at certain sites on the DNA. The researchers discovered that as people age, the entropy of methylation at many locations changes in a reproducible way. Sometimes it increases, reflecting more random patterns, and sometimes it decreases, showing more uniformity. These shifts are not always tied to how much methylation is happening, which suggests entropy provides new information beyond what traditional methods can offer. To test how well this new metric could predict age, the team used both statistical and machine learning models. They found that methylation entropy predicted age as accurately as traditional methods, and the best results came from combining entropy with other measurements like average methylation and a method called CHALM. These combined models were able to estimate age with an average error of just five years. "[...] methylation entropy is measuring different properties of a locus compared to mean methylation and CHALM, and that loci can become both more or less disordered with age, independently of whether the methylation is increasing or decreasing with age." This research supports the growing theory that aging is partly caused by a gradual loss of epigenetic information—the biological “instructions” that help keep our cells working properly. This insight also connects with recent studies suggesting that restoring this lost information might reverse some signs of aging. While more research is needed to study methylation entropy in other tissues, this work points to a more precise and powerful way to measure biological aging, which could influence the future of aging-related treatments and therapies.

Breast cancer survivors are living longer than ever, thanks to research and medical advances, but new studies suggest that some treatments may come with a hidden cost: accelerated aging. A recent study, titled “Accelerated aging associated with cancer characteristics and treatments among breast cancer survivors,” published in Aging (Aging-US), reveals that breast cancer and its treatments may speed up biological aging, with effects lasting up to a decade post-diagnosis. Breast Cancer and Aging Breast cancer is one of the most common cancers among women worldwide. Medical advancements have dramatically improved survival rates, making it one of the most treatable forms of cancer. Yet, many survivors report lasting symptoms like fatigue, memory issues, and reduced vitality that resemble accelerated aging. This pattern has led scientists to investigate whether treatments for breast cancer might be contributing to biological age acceleration.

BUFFALO, NY — April 14, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 3, on March 4, 2025, titled “Deciphering age-related transcriptomic changes in the mouse retinal pigment epithelium.” The study, led by first authors Sushil K. Dubey and Rashmi Dubey with corresponding author Mark E. Kleinman from East Tennessee State University, reveals that aging causes inflammation, oxidative stress, and gene disruption in the retinal pigment epithelium (RPE), a vital layer of cells in the eye. These changes may explain why older adults are more vulnerable to age-related eye diseases. The researchers also developed a human cell model to study retinal aging and test future therapies. The RPE plays a key role in maintaining retinal health. It recycles light-sensitive molecules, supports the visual cycle, and protects the retina from damage. When this layer becomes damaged, vision problems such as age-related macular degeneration can develop. In this study, researchers compared gene activity in RPE cells from young and aged mice. They found that aging increased the activity of genes involved in immune system responses, inflammation, and oxidative stress, three known triggers of tissue damage. At the same time, genes related to vision and light detection became less active, weakening the RPE’s ability to support healthy vision. To reinforce these findings, the research team also aged human RPE cells in the lab. Over time, these cells showed the same patterns: inflammation increased, while genes tied to visual function decreased. This human cell model offers a practical way to explore how RPE degeneration happens over time and how it might be slowed down or reversed. The research also identified “hub genes,” which are central players of the gene networks involved in RPE aging. These are connected to immune signaling, oxidative damage, and changes in the eye’s structural support. Many of these genes are already known to be involved in age-related retinal degeneration, so they may become important targets for future treatments aimed at protecting vision in older adults. “GO annotation of downregulated genes included processes related to visual perception, sensory perception of light stimulus, detection of light stimulus, detection of visible light, detection of external stimulus, detection of abiotic stimulus, phototransduction, cellular response to interferon-beta, response to interferon-beta, and response to light stimulus.” By mapping how the RPE changes with age at the molecular level, this study provides a clearer understanding of why aging leads to eye disease. It also introduces a reliable laboratory model that researchers can use to test new therapies. Altogether, the work is a key step toward developing treatments to slow or prevent vision loss tied to retinal aging.

Paula Cilleros-Holgado from Pablo de Olavide University discusses a #research paper she co-authored that was #published in Volume 17, Issue 2 of Aging (Aging-US), entitled “Mitochondrial dysfunction, iron accumulation, lipid peroxidation, and inflammasome activation in cellular models derived from patients with multiple sclerosis.” DOI - https://doi.org/10.18632/aging.206198 Corresponding author - José Antonio Sánchez-Alcázar - jasanalc@upo.es Video interview - https://www.youtube.com/watch?v=wIV0lAHPA_M Abstract Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS). Despite advancements in managing relapsing active illness, effective treatments for the irreversible progressive decline in MS remain limited. Research employing skin fibroblasts obtained from patients with neurological disorders revealed modifications in cellular stress pathways and bioenergetics. However, research using MS patient-derived cellular models is scarce. In this study, we collected fibroblasts from two MS patients to investigate cellular pathological alterations. We observed that MS fibroblasts showed a senescent morphology associated with iron/lipofuscin accumulation and altered expression of iron metabolism proteins. In addition, we found increased lipid peroxidation and downregulation of antioxidant enzymes expression levels in MS fibroblasts. When challenged against erastin, a ferroptosis inducer, MS fibroblasts showed decreased viability, suggesting increased sensitivity to ferroptosis. Furthermore, MS fibroblasts presented alterations in the expression levels of autophagy-related proteins. Interestingly, these alterations were associated with mitochondrial dysfunction and inflammasome activation. These findings were validated in 7 additional patient-derived cell lines. Our findings suggest that the underlying stress phenotype of MS fibroblasts may be disease-specific and recapitulate the main cellular pathological alterations found in the disease such as mitochondrial dysfunction, iron accumulation, lipid peroxidation, inflammasome activation, and pro-inflammatory cytokine production.

BUFFALO, NY — April 9, 2025 — A new #research paper was #published in Aging (Aging-US) Volume 17, Issue 3, on March 5, 2025, titled “Reproductive aging, preimplantation genetic testing for aneuploidy, and the diameter of blastocysts: does size matter?” In this study, a team led by first author Jakub Wyroba from the Malopolski Institute of Fertility Diagnostics and Treatment and Andrzej Frycz Modrzewski Krakow University, and corresponding author Pawel Kordowitzki from Harvard Medical School, Nicolaus Copernicus University, and Charité, found that the size of an embryo and whether it has started hatching can help predict its genetic health. This insight could help fertility clinics select better embryos during in vitro fertilization (IVF), especially in countries or situations where advanced genetic testing is not available. As more women are choosing to have children later in life, fertility challenges related to age are becoming more common. Older maternal age is linked with a higher risk of chromosomal problems in embryos, which can reduce the success of IVF. To identify healthy embryos, many clinics use a test called preimplantation genetic testing for aneuploidy (PGT-A). However, PGT-A is expensive and not available in all countries. This study explored whether embryo quality could be predicted using physical features alone. During IVF, embryos develop in the lab for several days before being transferred into the uterus. Around day five or six, the embryo reaches a stage called the blastocyst. At this point, it begins to break out of its outer shell, called the zona pellucida. This process is called hatching, and it is an important step before the embryo can attach to the uterus and begin a pregnancy. The researchers examined 1150 embryos from women aged 26 to 45 who underwent IVF. They looked at whether the embryos were already starting to hatch and how big they were. They then compared these features with results from genetic tests. They found that smaller embryos that were already hatching were more likely to be chromosomally normal, also called “euploid.” “Of the 1150 blastocysts that underwent PGT-A analysis in this study, 49% were aneuploid.” For women over 35, 51% of small hatching embryos were euploid, compared to just 38% of larger ones that had not started to hatch. Among younger women under 35, the difference was even greater—73% of small hatching embryos were euploid, compared to 58% of large, unhatched ones. The research team also looked at what happened after the embryos were transferred. When embryos were already known to be euploid, both large and small embryos led to similar pregnancy rates. This means the size and hatching behavior mostly matter when genetic testing is not done. This study offers new guidance for IVF clinics. Choosing a small hatching embryo may improve the chances of success, especially for women of advanced age and in clinics that do not use PGT-A. This finding could help make fertility treatment more accessible and affordable. As fertility science continues to advance, insights like this provide practical tools to improve outcomes and bring new hope to individuals and families trying to conceive through IVF.

BUFFALO, NY — April 7, 2025 — A new #research paper was #published in Aging (Aging-US) on March 18, 2025, in Volume 17, Issue 3, titled “Mitochondrial oxidative stress or decreased autophagy in osteoblast lineage cells is not sufficient to mimic the deleterious effects of aging on bone mechanoresponsiveness.” Researchers from the University of Arkansas for Medical Sciences, led by first author Ana Resende-Coelho and corresponding authors Melda Onal and Maria Almeida, investigated why bones become less responsive to exercise as people age. They studied two well-known aging-related cellular changes: oxidative stress (a buildup of harmful molecules inside cells) and reduced autophagy (a slowdown in the cell’s ability to clean out and recycle damaged parts) to determine whether these could explain the decline in bone strength. Their findings revealed that these changes alone are not enough to account for the reduced bone-building response seen with aging. Physical activity is known to strengthen bones by creating mechanical stress, which activates bone cells like osteocytes to promote new bone formation. However, this process becomes less effective with age, increasing the risk of bone loss and fractures in older adults. The study aimed to uncover why this response weakens over time by focusing on specific age-related changes inside bone-forming cells. “The bone response to loading is less effective with aging, but the cellular and molecular mechanisms responsible for the impaired mechanoresponsiveness remain unclear.” The research team used a well-established mouse model in which pressure was applied to the tibia, simulating the effects of exercise. As expected, bones from older mice showed a weaker response compared to those of younger mice. However, when the researchers examined younger mice genetically modified to have either high oxidative stress or impaired autophagy, as seen in aging, their bones still responded normally to mechanical loading. The researchers also found that damage to the bone’s osteocyte network, a system of cells that helps sense and respond to mechanical forces, did not prevent a healthy bone-building response in mice with autophagy deficiencies. This challenges the long-standing idea that deterioration of this cell network is a main cause of age-related bone decline. These results are significant because they eliminate two widely suspected causes of the aging skeleton’s reduced responsiveness to exercise. While oxidative stress and autophagy dysfunction are common in older bone, they are not solely responsible for its reduced ability to grow stronger under physical stress. The authors suggest that future studies should explore other possible factors, such as changes in energy metabolism or how bone cells communicate. Overall, this study shows that bone aging is more complex than previously thought. Protecting bone health in older adults may require new strategies that go beyond targeting oxidative stress or autophagy.

Could a class of drugs that clear aging cells also help treat Alzheimer’s disease? A recent study, featured as the cover for Aging (Volume 17, Issue 3), titled “Differential senolytic inhibition of normal versus Aβ-associated cholinesterases: implications in aging and Alzheimer’s disease,” suggests they might—and with remarkable precision. Understanding Alzheimer’s Disease Alzheimer’s disease is a progressive neurological disorder that gradually steals memory, independence, and a person’s sense of identity. A defining feature of Alzheimer’s is the buildup of amyloid-β (Aβ) plaques—sticky protein clumps that interfere with communication between brain cells. This disruption is closely linked to changes in a group of enzymes called cholinesterases, especially acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). These enzymes normally play a vital role in regulating neurotransmitters critical for memory, learning, and cognitive function. In Alzheimer’s, however, their behavior changes significantly, particularly when they interact with Aβ plaques. The Study: Exploring Senolytics for Alzheimer’s Enzyme Inhibition A research team from Dalhousie University in Canada looked into whether senolytic compounds—a class of drugs that eliminate damaged, aging cells often referred to as “zombie” cells—could also target the harmful forms of cholinesterase enzymes found in Alzheimer’s disease. Their goal was to see if these compounds could selectively inhibit the disease-associated versions of AChE and BChE, without affecting the healthy forms that are essential for normal brain function.

BUFFALO, NY — April 1, 2025 — A new #research paper was #published in Aging (Aging-US) on March 29, 2025, as the #cover of Volume 17, Issue 3, titled “Differential senolytic inhibition of normal versus Aβ-associated cholinesterases: implications in aging and Alzheimer’s disease.” In this study, a research team from Dalhousie University, led by Sultan Darvesh, discovered that certain anti-aging compounds, known as senolytics, can block harmful brain enzymes linked to Alzheimer’s disease (AD) without affecting healthy ones. Senolytics are compounds that help clear out damaged or “zombie” cells that build up with age and contribute to inflammation and tissue dysfunction. This work provides new insight into how AD-related damage can be precisely targeted, leading the way for safer treatments that protect memory and brain health in older adults. Alzheimer’s disease is one of the most common causes of memory loss and dementia. A hallmark of the disease is the buildup of sticky protein clumps in the brain, known as amyloid-beta plaques. Two enzymes—acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)—are found near these plaques. While these enzymes play important roles in brain function, they can also contribute to AD progression when they attach to plaques. Drugs that target these enzymes are already used to help with memory, but they often block both harmful and healthy forms, which can cause unwanted side effects. To investigate a better solution, researchers tested six compounds that are known for their anti-aging or brain-boosting properties. They wanted to know if these compounds could block only the harmful AChE and BChE enzymes forms linked to Alzheimer’s disease. Using brain tissue samples from AD patients and enzyme activity assays, they discovered that compounds such as dasatinib and nintedanib, both senolytics, were able to block the forms of AChE and BChE associated with amyloid-beta plaques. These compounds did not affect normal brain enzymes, though. “We show that the selected senolytics and nootropic inhibit ChEs associated with plaques but not the enzymes associated with normal neural elements.” The study also used computer modeling to explore how these compounds interact with the enzymes. The models showed that the enzymes change shape when near plaques, making them easier for certain compounds to target. This change may explain how the drugs can selectively affect only the diseased areas of the brain. While not all compounds worked equally well, the findings offer a new strategy for treating AD. By focusing on the differences between healthy and diseased enzyme forms, researchers may be able to design more precise and effective therapies. This selective approach could improve memory, reduce inflammation, and avoid the side effects of AD’s current treatments. In summary, this research opens new possibilities for treating Alzheimer’s disease in a more targeted way. It also highlights how discoveries in aging and brain health can work together to create better therapies for neurodegenerative diseases.

BUFFALO, NY — March 26, 2025 — A new #research paper was #published in Aging (Aging-US) on January 29, 2025, in Volume 17, Issue 2, titled “Diet, lifestyle and telomere length: using Copula Graphical Models on NHANES data.” Researchers Angelo M. Tedaldi, Pariya Behrouzi, and Pol Grootswagers from Wageningen University and Research used data from the National Health and Nutrition Examination Survey (NHANES) to explore how diet and lifestyle affect telomere length, a key marker of cellular aging. They found that inflammation—rather than diet, exercise, or smoking—had the strongest and most consistent association to telomere shortening. The findings suggest that reducing inflammation may be more effective than dietary changes in slowing down the aging process at the cellular level. Telomeres are protective caps at the ends of chromosomes that get shorter as we age. When they become too short, cells lose the ability to divide properly, which can contribute to aging and age-related diseases. Previous studies suggested that healthy habits might protect telomeres, but many focused on a small number of factors and did not account for important elements like inflammation or differences in blood cell composition. This study aimed to take a more complete, data-driven approach. The research team analyzed health data from over 7,000 U.S. adults collected between 1999 and 2002. Using a method called Copula Graphical Modeling, they examined more than 100 variables—such as diet, physical activity, smoking, and blood biomarkers—across three age groups: Young (20–39 years), Middle (40–59 years), and Old (60–84 years). They found that telomere length was most strongly associated to age, levels of C-reactive protein (CRP)—a common marker of inflammation—and gamma-tocopherol, a form of vitamin E found in the blood. Higher CRP levels were consistently associated with shorter telomeres, especially in younger and middle-aged adults. The results suggest that while lifestyle factors like diet and exercise still play a role, their impact on aging may be indirect—mainly through their influence on inflammation. This finding shifts the focus toward managing chronic inflammation as a potentially more effective way to preserve telomere length and promote healthy aging. “The central role played by CRP and the marginal role of antioxidants suggests that telomeres are particularly vulnerable not to oxidative stress, but to inflammation; and they should be protected against it.” The study challenges earlier research that looked at individual lifestyle factors isolated. By using a more advanced and inclusive method, this analysis offers a clearer picture of how health behaviors, biological markers, and aging are connected. Although this research cannot prove a cause-and-effect relationship, it strongly supports the idea that inflammation plays a key role in cellular aging. The authors recommend further long-term studies to better understand how inflammation affects telomere length over time. In the meantime, reducing chronic inflammation may be one of the most important steps to help support healthy aging and reduce the risk of age-related diseases.
