76: Walking with Survivors of Gun Violence with Nelba Márquez-Greene

Cancer treatment is moving toward a more precision-based approach, where therapies are guided not just by the tumor’s location but also by its genetic features. Mutations in cancer cells can point to specific drugs that may be more effective for certain patients. However, detecting these mutations often requires broad and detailed analysis. This is where comprehensive genomic profiling becomes especially important.

One of the main challenges in cancer care is that many existing genetic tools focus on only a limited number of mutations. As a result, some treatment opportunities may be missed. Certain mutations are also difficult to detect because they occur at low levels or exist in complex forms, such as gene fusions. Without advanced screening methods, these changes may go unnoticed.

To address these challenges, researchers from Exact Sciences Corporation conducted a large-scale study using a broad genomic screening approach. The findings were recently published in the journal Oncotarget.

Comprehensive Genomic Profiling in Cancer: Insights from Over 10,000 Tumors

BUFFALO, NY — December 16, 2025 — A new #research paper was #published in Aging-US on December 10, 2025, titled “Theobromine is associated with slower epigenetic ageing.”

In this study, led by Ramy Saad from King’s College London and Great Ormond Street Hospital for Children NHS Foundation Trust, alongside Jordana T. Bell from King’s College London, researchers found that higher levels of theobromine, a natural compound found in cocoa, are associated with slower biological aging in humans. The findings suggest that theobromine may support healthy aging.

Epigenetic aging refers to biological changes that affect how genes function over time. It is measured using blood-based markers such as DNA methylation and telomere length, which together provide a more accurate picture of aging than chronological age.

In this work, researchers analyzed data from two large European studies. In 509 women from the TwinsUK cohort, they found that higher blood levels of theobromine were associated with slower aging, especially based on GrimAge, an epigenetic clock that predicts the risk of age-related disease and early death. The results were confirmed in 1,160 men and women from the German KORA study.

“We initially tested for the association between six metabolites found in coffee and cocoa, and epigenetic measures of ageing in blood samples from 509 healthy females from the TwinsUK cohort (median age = 59.8, IQR = 12.81, BMI = 25.35).“

Importantly, theobromine’s effects were independent of related compounds such as caffeine. Even after adjusting for these other substances and different lifestyle factors, the association with slower aging remained strong. The study also associated higher theobromine levels with longer telomeres, another marker of healthy aging.

While theobromine is commonly found in cocoa and chocolate, the study does not suggest increasing chocolate intake. However, it highlights the potential of everyday dietary components such as theobromine to influence aging. These findings support growing evidence that certain plant-based compounds may play a role in promoting long-term health. By identifying a connection between theobromine and slower biological aging, the study opens new directions for research into nutritional strategies for healthy aging.

Theobromine From Cocoa Linked to Slower Biological Aging

BUFFALO, NY - December 17, 2025 – A new #research paper was #published in Oncotarget (Volume 16) on December 15, 2025, titled “Machine learning-based survival prediction in colorectal cancer combining clinical and biological features.”

In this study, led by Lucas M. Vieira from the University of Brasília and the University of California San Diego, researchers used machine learning to predict survival in patients with colorectal cancer. They built a model by combining biological markers with clinical data. This approach could help improve prognosis and guide treatment strategies for one of the world’s most common and deadly cancers.

The team analyzed data from over 500 patients, using clinical details such as age, chemotherapy status, and cancer stage, along with molecular features like gene expression and microRNAs. Their goal was to improve how clinicians identify high-risk patients and make outcome predictions more precise. Researchers evaluated three different patient data scenarios using different machine learning techniques. The best-performing was an adaptive boosting model, which achieved 89.58% accuracy. This approach showed that integrating clinical and biological data led to significantly better predictions than using either data type alone. 

Among the biological markers, the gene E2F8 was consistently influential in all patient groups and is known to play a role in tumor growth. Other important markers included WDR77 and hsa-miR-495-3p, which are also associated with cancer development. Key clinical predictors included cancer stage, patient age, lymph node involvement, and whether chemotherapy was administered.

“The proposed method combines biological and clinical features to predict patient survival, using as input data from patients from the United States, available in the TCGA database.”

Unlike earlier models that relied on either clinical or molecular data alone, this study demonstrates the added value of combining both. Ensemble methods, which merge multiple learning algorithms, provided more stable and consistent results across all patient groups tested.

These research findings could lead to new tools that help clinicians better predict how a patient's disease might progress or respond to treatment. The study also highlights the importance of collecting complete clinical information, such as lifestyle factors, which were missing from the dataset but could enhance future predictions.

Overall, the study demonstrated how machine learning can support more accurate and personalized survival predictions in colorectal cancer. It also points to potential future research on markers like E2F8, which may be useful for monitoring or targeted therapy.

Aging-US Now on ResearchGate, Enhancing Visibility for Authors and Readers

BUFFALO, NY — December 19, 2025 — A new #research paper was #published in Volume 17, Issue 11 of Aging-US on November 18, 2025, titled “Epigenetic age predicts depressive symptoms during the COVID-19 pandemic in the Canadian Longitudinal Study on Aging: importance of biological sex.”

This study, led by Cindy K. Barha of the University of Calgary and the University of British Columbia, along with Teresa Liu-Ambrose of the University of British Columbia, found that older women with a younger biological age measured years before the COVID-19 pandemic experienced a greater increase in depressive symptoms during the early lockdown period. These findings could help shape future mental health strategies, particularly for women with high emotional or caregiving demands.

Epigenetic age is a biological marker that reflects how the body is aging and may differ from a person’s actual age. Using long-term data from the Canadian Longitudinal Study on Aging (CLSA), the researchers investigated whether epigenetic age could predict changes in mental health during a major public health crisis. The study included over 600 adults, with an average baseline age of 63, and used two widely accepted epigenetic clocks, the DNAmAge and the Hannum Age, to estimate biological age. Depressive symptoms were tracked at four time points between 2012 and 2020, including during the height of the pandemic.

“The mean participant chronological age at study entry was 63±10 years (46% female).”

The analysis showed that in women, a younger biological age predicted a greater rise in depression during the early phase of the COVID-19 pandemic. This was not observed in men or in individuals with older biological ages.

The study challenges the common belief that a younger biological age always signals better mental or physical resilience. The researchers suggest that women with younger biological profiles may have been more socially or professionally active before the pandemic. When lockdowns disrupted daily routines and social connections, these individuals may have experienced more emotional distress.

Additional factors, such as reduced physical activity, loss of routine, and decreased social interaction, known to affect both mental health and biological aging, may have had a stronger emotional effect on this group. The findings highlight the importance of considering biological sex when studying how aging affects mental well-being during stressful events.

Although the study has some limitations, including the time gap between biological age measurement and the pandemic, it gives valuable insights into how biological and social factors interact during periods of crisis. Future research could use epigenetic clocks to better identify individuals at greater risk of mental health challenges during large-scale public health emergencies.

Overall, this study adds to the growing field of social epigenetics and suggests that biological age may support more targeted public health planning, especially for older adults.

Younger Biological Age May Increase Depression Risk in Older Women During COVID-19

BUFFALO, NY — December 23, 2025 — A new #research paper was #published in Volume 17, Issue 11 of Aging-US on November 25, 2025, titled “A natural language processing–driven map of the aging research landscape.”

In this study, Jose Perez-Maletzki from Universidad Europea de Valencia and Universitat de València, together with Jorge Sanz-Ros from Stanford University School of Medicine, used artificial intelligence (AI) to analyze a century of global aging research, revealing shifts in focus and highlighting underexplored areas.

The team analyzed over 460,000 scientific abstracts published between 1925 and 2023 to identify key themes, trends, and research gaps in the study of aging. Their goal was to provide a comprehensive, unbiased view of how the field has evolved and where future research could have the greatest impact.

The study found that aging research has moved from basic cellular studies and animal models to a growing focus on clinical topics, particularly age-related diseases such as Alzheimer’s and dementia. Using natural language processing and machine learning, the researchers grouped publications into thematic clusters and tracked how interest in each topic changed over time.

“By integrating Latent Dirichlet Allocation (LDA), term frequency-inverse document frequency (TF-IDF) analysis, dimensionality reduction and clustering, we delineate a comprehensive thematic landscape of aging research.”

One key finding was the growing separation between basic biological studies and clinical research. While both areas have grown significantly, they often progress independently with limited overlap. Clinical studies tend to focus on geriatrics, healthcare, and neurodegenerative diseases, while basic science emphasizes cellular mechanisms such as oxidative stress, telomere shortening, mitochondrial dysfunction, and senescence. The authors note that this lack of integration limits the translation of laboratory discoveries into medical applications.

The study also showed that some emerging topics, such as autophagy, RNA biology, and nutrient sensing, are expanding rapidly but remain separated from clinical applications. In contrast, long-established links, such as those between cancer and aging, remain strong. The analysis also highlighted that potentially important associations, such as those between mitochondrial dysfunction and senescence or epigenetics and autophagy, are rarely studied and may be new research opportunities.

This AI-driven analysis offers a new way to guide future research by identifying how different areas of aging science are interconnected or isolated. It also highlights how research priorities may be shaped by policy or funding trends, as seen in the heavy focus on Alzheimer’s disease. 

As the global population continues to age, understanding how biological processes relate to clinical outcomes is critical. This study not only offers a historical map of aging science but also serves as a tool to support more connected, interdisciplinary, and effective future research.
