BUFFALO, NY - November 10, 2025 – A new #research paper was #published in Oncotarget (Volume 16) on November 6, 2025, titled “Anti-DNA virus agent cidofovir - loaded green synthesized cerium oxide nanoparticles (Nanoceria): Nucleic acids (DNA and RNA) binding affinity and cytotoxicity effects.”

In this study, led by Nahid Shahabadi from Razi University in Kermanshah, researchers developed an environmentally friendly approach to enhance the performance of cidofovir, a drug used to treat infections caused by DNA viruses. The work responds to the growing need for therapies that are safer, more effective, and better targeted.

The research team developed a new compound by loading cidofovir onto green-synthesized cerium oxide nanoparticles (nanoceria), known as CDV-CeO2 NPs. This method combines the drug’s antiviral and anticancer properties with the biological activity of nanoceria, which is known for its antioxidant, anti-inflammatory, and tumor-targeting effects. To avoid toxic chemicals, the nanoparticles were synthesized using quince fruit peel extract, making the process more sustainable and suitable for medical applications.

Laboratory experiments showed that the CDV-CeO2 nanoparticles were significantly more effective at killing breast cancer cells than either cidofovir or cerium oxide nanoparticles alone. At the highest tested concentration, the new compound destroyed more than 97% of cancer cells, compared to 72% with cidofovir alone and 50% with nanoparticles alone. These findings suggest that the combined formulation enhances anticancer activity and may allow for lower drug doses with fewer side effects.

To understand how these nanoparticles interact with genetic material, the team studied their binding to DNA and RNA, two key molecules involved in cancer development and viral replication. CDV-CeO2 nanoparticles showed strong binding affinity through two mechanisms: groove binding, which fits into natural curves of the genetic molecule strands, and intercalation, which inserts between base pairs. The nanoparticles formed stable complexes that responded to temperature, indicating reliable interactions in biological systems.

“The novelty of this work lies in the innovative green synthesis method, the dual-functional therapeutic application, and the enhanced biological activity of the CDV-CeO2 NPs, which collectively position these nanoparticles as promising candidates for future cancer and antiviral therapies.”

This research presents a potential new strategy for improving drug targeting and delivery using green nanotechnology. The approach could lead to more effective treatments for diseases such as breast cancer and infections caused by human papillomavirus (HPV) and other DNA viruses. However, further research, including animal and clinical studies, is needed to confirm the safety and long-term effectiveness of this treatment.

Overall, this study represents a significant step toward combining natural materials with nanomedicine to create more efficient therapies. If supported by future research, CDV-CeO2 nanoparticles could offer a new generation of dual-action treatments.

Eco-Friendly Nanoparticles Improve Cidofovir’s Anticancer and Antiviral Effects

BUFFALO, NY — November 11, 2025 — A new #research paper was #published in Volume 17, Issue 10 of Aging-US on October 1, 2025, titled “L-β-aminoisobutyric acid (L-BAIBA) in combination with voluntary wheel running exercise enhances musculoskeletal properties in middle-age male mice.”

In this study led by first author Julian A. Vallejo and corresponding author Michael J. Wacker from the University of Missouri, Kansas City, researchers investigated how L-β-aminoisobutyric acid (L-BAIBA), a natural compound released during exercise, works together with regular physical activity to improve muscle and bone health in middle-aged male mice. The findings may support new strategies to maintain musculoskeletal health in aging populations, especially those at risk for mobility loss or osteoporosis.

Muscle and bone strength naturally decline with age, increasing the risk of falls, fractures, and reduced quality of life. While exercise remains the most effective way to counteract this deterioration, it is often difficult for older individuals to maintain sufficient activity levels to see results. L-BAIBA, a molecule naturally produced during physical activity, is known to promote energy metabolism and support muscle and bone cells. This study explored its potential to work in synergy with endurance exercise to maximize health benefits in aging bodies.

Researchers studied 12-month-old male mice that were split into different groups. Some remained sedentary, while others exercised freely on running wheels. Half of each group received daily L-BAIBA supplementation. After three months, the mice that received both the supplement and exercise showed greater improvements than those receiving either one alone. The soleus, a slow-twitch muscle essential for endurance and balance, grew larger and stronger only in the combined treatment group. These muscles also shifted to a more fatigue-resistant fiber type and had a larger number of oxidative fibers.

“To investigate this hypothesis, we subjected 12-month-old (as a model of middle-age) male C57BL6 mice to voluntary wheel running (VWR) with L-BAIBA (100mg/kg/day) (VWR+L-BAIBA), VWR alone, L-BAIBA alone, or none (CTRL) for three months.”

The study also showed significant improvements in bone health. Mice that received both exercise and L-BAIBA developed thicker and denser trabecular bone, along with reduced fat levels in the bone marrow, indicators of stronger, healthier bones. These changes were not observed in the groups that only exercised or only received L-BAIBA. Although the compound caused minor changes in heart electrical activity, it did not affect heart size or overall function, suggesting it is safe in this setting.

These findings suggest that L-BAIBA may enhance the benefits of physical activity by supporting muscle strength and bone structure, particularly in slow-twitch muscle fibers. This combination could serve as a therapeutic strategy to help older adults, including those unable to engage in regular exercise, maintain musculoskeletal health.

As the aging population grows, there is a growing need for solutions that support muscle and bone health without requiring strenuous activity. This research highlights the potential of natural, exercise-related molecules like L-BAIBA to help maintain mobility and strength throughout aging.

Exercise and L-BAIBA Supplement Boost Muscle and Bone Health in Aging Mice

Synucleinopathies are a group of age-related neurological disorders, including Parkinson’s disease, dementia with Lewy bodies, and multiple system atrophy. Most individuals are not diagnosed until these diseases have significantly progressed, as early symptoms, such as a reduced sense of smell, subtle cognitive or motor changes are too vague to serve as reliable indicators. 

To uncover specific biological signs that appear earlier and clearly point to the disease process, researchers from Saarland University developed a study titled “Brain region-specific and systemic transcriptomic alterations in a human alpha-synuclein overexpressing rat model,” featured as the cover Aging-US, Volume 17, Issue 10.

Alpha-Synuclein Overexpression in Rats Reveals Early Clues to Synucleinopathies

We practice meditation because the present moment is the only place where we can truly find ourselves, love others, and be loved by the divine. This is why we gather, why we sit, why we breathe together. We practice surrendering to what lies beyond our control and responding rather than reacting to life's challenges. We cultivate curiosity about what's arising within and around us, learning to do difficult things like changing and growing. Because we trust there's a limitless reservoir of strength, compassion, and resilience flowing through us at every moment.

71: "Why We Practice" - reflection and meditation with Brandon Nappi

BUFFALO, NY - November 12, 2025 – A new #research paper was #published in Oncotarget (Volume 16) on November 6, 2025, titled “LRIG1-3 in gliomas: LRIG1 protein expression decreased in higher grade gliomas.”

In this study by Marlene Happe, Saskia Kuhl, Lukas Görtz, Roland Goldbrunner and Marco Timmer, from the University of Cologne, researchers found that the LRIG1 protein, which may help suppress tumors, is present at lower levels in more aggressive gliomas, a type of brain tumor. The findings suggest that LRIG1 could serve as a useful marker for tumor severity and potentially as a target for future therapies.

Gliomas are the most common malignant brain tumors in adults and carry a poor prognosis, particularly in their most severe form, glioblastoma. This study investigated three related proteins: LRIG1, LRIG2, and LRIG3, which are involved in regulating cell growth signals. While LRIG1 and LRIG3 have shown tumor-suppressing effects in previous studies, LRIG2 is thought to support tumor growth. The researchers analyzed tumor samples from patients to understand how these proteins behave across different glioma grades and how they respond to chemotherapy.

The results showed that LRIG1 protein levels decline significantly as tumor grade increases. Low-grade gliomas displayed much higher LRIG1 expression than high-grade tumors. Among high-grade tumors, primary glioblastomas had the lowest levels of LRIG1. Interestingly, secondary glioblastomas, which typically develop from lower-grade tumors, had higher levels of LRIG1 than primary glioblastomas. This difference may contribute to their relatively better clinical outcomes. These results highlight LRIG1’s potential role in slowing tumor progression.

In contrast, LRIG2 showed a more complex pattern. While its gene expression was higher in lower-grade tumors, the actual protein levels were slightly elevated in higher-grade ones, which are more aggressive. This mismatch suggests that processes occurring after gene transcription may influence how much LRIG2 protein is produced. 

“However, our data on LRIG2 indicate that its role in glioma may be more complex than previously thought, warranting further investigation.”

Concerning LRIG3, it was found in higher amounts in glioma tissue compared to surrounding healthy tissue. Its expression was particularly high in low-grade tumors. However, chemotherapy did not consistently affect LRIG3 levels, and results varied depending on tumor type and treatment status.

Overall, the study suggests that members of the LRIG protein family, especially LRIG1, could serve as important biomarkers to distinguish between glioma types and grades. Although chemotherapy did not significantly change their expression in most cases, these proteins have high potential as diagnostic tools or therapeutic targets. Further research is needed to better understand their roles in glioma development and treatment response.

Aging-US Supports the Future of Aging Research Mixer 2025

BUFFALO, NY — November 13, 2025 — A new #research paper was #published in Volume 17, Issue 10 of Aging-US on October 3, 2025, titled “The role of phenylalanine and tyrosine in longevity: a cohort and Mendelian randomization study.”

In this study led by Jie V. Zhao, Yitang Sun, Junmeng Zhang, and Kaixiong Ye from the University of Hong Kong and the University of Georgia, researchers investigated whether two amino acids, phenylalanine and tyrosine, affect  how long people live (lifespan). The results suggest that higher levels of tyrosine are linked to shorter life expectancy in men, pointing to potential sex-specific approaches to promoting longevity.

Phenylalanine and tyrosine are amino acids involved in metabolism and brain function. Both are found in protein-rich foods and dietary supplements, but their long-term effects on aging are not well understood. Tyrosine, in particular, is a building block of neurotransmitters such as dopamine, which regulate mood and cognitive function, making it a molecule of interest in aging research.

The study analyzed data from more than 270,000 individuals in the UK Biobank. Using both observational and genetic methods, the researchers examined the associations between blood levels of phenylalanine and tyrosine with overall mortality and predicted lifespan. Although both amino acids were initially linked to higher mortality risk, only tyrosine showed a consistent and potentially causal association with reduced life expectancy in men. Genetic analyses estimated that elevated tyrosine levels could shorten men’s lifespan by nearly one year. No significant effect was observed in women.

These findings remained consistent even after adjusting for related factors, including the role of phenylalanine. This suggests that tyrosine may independently influence aging. The researchers also observed that men tend to have higher tyrosine levels than women, which could partly explain the gender gap in lifespan.

“Phenylalanine showed no association with lifespan in either men or women after controlling for tyrosine.”

The exact mechanisms behind this effect are still under investigation. However, tyrosine’s involvement in insulin resistance and the production of stress-related neurotransmitters may be contributing factors. Insulin resistance is associated with many age-related diseases, and hormone-related pathways influenced by tyrosine may differ between men and women, potentially explaining the sex-specific outcomes.

Although tyrosine is commonly marketed as a supplement for enhancing focus and mental performance, the study raises concerns about its long-term impact on lifespan. While the researchers did not directly study tyrosine supplementation, their findings suggest that people with high tyrosine levels may benefit from dietary adjustments. Strategies such as protein restriction could help reduce tyrosine levels and support healthier aging.

Further studies are needed to confirm these findings and explore whether diet and lifestyle changes can safely lower tyrosine levels to promote longevity.

High Tyrosine Levels Linked to Shorter Lifespan in Men

BUFFALO, NY – November 17, 2025 – A new #research perspective was #published in Oncotarget (Volume 16) on November 14, 2025, titled “A personal perspective of patient-centred clinical trials.”

In this perspective, led by corresponding author Jia Liu of The Kinghorn Cancer Centre, St Vincent’s Hospital, the University of New South Wales, and the Garvan Institute of Medical Research, three early-phase clinical trial participants — Trevor Tyne, Elizabeth Ivimey, and Leanne Duggan — reflect on their personal experiences with experimental cancer treatments. Their stories offer a unique perspective on the patient journey through early-phase trials and emphasize the need to design clinical research that prioritizes patients’ needs, dignity, and lived realities. The authors highlight both the life-changing opportunities that trials can provide and the systemic barriers that still prevent many patients from participating.

This perspective captures a turning point in how early-phase trials are viewed. Once considered a last resort, these trials are now increasingly offered earlier in treatment, especially with the rise of biomarker-guided therapies. In this context, the patient experience has become critical. The authors outline key benefits of participation, including access to novel therapies, ongoing medical monitoring, emotional support, and a strong sense of purpose in contributing to future medical advancements. However, they also point out significant challenges, such as restrictive eligibility criteria, high financial and logistical burdens, and communication gaps between patients and trial staff.

“While no trial guarantees success, the level of support, access to innovative therapies, and sense of contribution to medical progress can be profoundly meaningful.” 

Each narrative provides insight into the clinical trial experience. One patient explains how living with a visual impairment required tailored accessibility support throughout the trial process Another shares how genomic testing led to targeted treatment after standard options failed. Despite their different diagnoses and circumstances, all three stories reflect resilience, hope, and a shared call for trial designs that better reflect the realities of diverse patients.

To address these issues, the authors propose a number of improvements to trial design and delivery. These include expanding eligibility criteria, offering financial and logistical assistance, improving communication training for research staff, and introducing dedicated trial navigators to help guide patients through complex processes. They also focus on the importance of involving patient advocates in trial design and ensuring smoother transitions for patients moving between treatment centers.

While early-phase trials focus on safety and effectiveness, the authors argue they must also be guided by core values like ethics and patient empowerment. This perspective serves as a reminder that the future of cancer research depends not only on scientific innovation, but on an honest partnership between patients and the research community.

By sharing these real-world experiences, the article encourages a broader conversation about how to make clinical trials more responsive to the people they are designed to serve.
