  • EphA2 Signaling in Eye Lens Aging: Wild-Type, Knockout, and Aging Mice

    EphA2 Signaling in Eye Lens Aging: Wild-Type, Knockout, and Aging Mice
    2024/11/13
    BUFFALO, NY- November 13, 2024 – A new #research paper was #published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), on October 25, 2024, Volume 16, Issue 20, titled, ”Canonical ligand-dependent and non-canonical ligand-independent EphA2 signaling in the eye lens of wild-type, knockout, and aging mice.“ Researchers from the School of Optometry and Vision Science Program at Indiana University have uncovered important new insights into how the aging affects the eye lens and contributes to cataract formation, a condition impacting millions worldwide. This study focuses on the EphA2 protein, traditionally associated with cancer, which researchers have now identified as essential for maintaining the lens’s clarity and function as it ages. Cataracts are the leading cause of blindness worldwide, primarily affecting older adults, yet the precise biological mechanisms behind their formation remain unclear. This research sheds light on the role of the EphA2 protein receptor in the eye lens, revealing that it operates through two distinct signaling pathways: a canonical (ligand-dependent) and a non-canonical (ligand-independent) pathway. By studying various groups of mice, including those lacking the EphA2 protein receptor and its ligand partner ephrin-A5, scientists observed how these signaling pathways change with age, affecting the organization and maturation of lens cells. Researchers Jenna L. Horner, Michael P. Vu, Jackson T. Clark, Isaiah J. Innis, and Catherine Cheng observed that EphA2’s canonical signaling, which organizes lens cells, remains stable in aging lens tissue, particularly in epithelial cells. They found that the non-canonical signaling pathway—previously associated primarily with aggressive cancer cells—increases with age in normal lens cells. This increase suggests that non-canonical signaling plays a crucial role in helping lens fiber cells mature and maintain their structure over time. “Here, we report that canonical ligand-mediated EphA2 activation is restricted to the lens epithelial cells and show the first evidence of physiological non-canonical EphA2 activity in a normal tissue.” This understanding could lead to new therapies targeting EphA2 to delay or prevent cataracts. In conclusion, this study represents a significant advance in understanding the cellular mechanisms behind lens aging and cataract development, potentially paving the way for new non-surgical cataract treatments.

  • Validating an Electronic Frailty Index in a National Health System

    Validating an Electronic Frailty Index in a National Health System
    2024/11/12
    BUFFALO, NY- November 12, 2024 – A new #research paper was #published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), on October 24, 2024, Volume 16, Issue 20, titled, "Development and validation of an electronic frailty index in a national health maintenance organization." The study, led by researchers Fabienne Hershkowitz Sikron, Rony Schenker, Yishay Koom, Galit Segal, Orit Shahar, Idit Wolf, Bawkat Mazengya, Maor Lewis, Irit Laxer and Dov Albukrek from Meuhedet Health Maintenance Organization (HMO) in collaboration with colleagues from the Joint-Eshel Organization and the Israeli Ministry of Health, introduces the Meuhedet Electronic Frailty Index (MEFI)—a digital tool designed to assess frailty in older people and identify those most at risk for serious health outcomes, such as hospitalization or death. As people live longer, identifying those at higher risk for health complications is essential to maintaining quality of life in older age. Frailty, a condition marked by increased vulnerability to adverse health outcomes, has emerged as a crucial predictor of health deterioration in older people. While frailty assessment tools exist, this study adapts and validates an Electronic Frailty Index (EFI) tailored specifically to Israeli data and healthcare infrastructure, enabling more targeted and culturally relevant assessments. The MEFI was developed using data from 120,986 individuals aged 65 and older, comprising different indicators, including physical, social, and cognitive deficits. The index classifies individuals as "fit," "mildly frail," "moderately frail," or "severely frail" and is integrated into Israel’s electronic health records system. Researchers found that patients with higher MEFI scores faced significantly increased risks of hospitalization or mortality within one year, with risk levels rising fourfold for the most frail compared to those classified as fit. According to the authors, “The findings also showed that the MEFI version we created is valid in predicting mortality or hospitalization and had better predictive accuracy compared to CCI,” underscoring its reliability in assessing health risks. This integration enables Meuhedet HMO to implement proactive and preventive care measures across its network. Beyond predicting hospitalization and mortality, the MEFI’s alignment with Israel’s National Social Security benefit system reinforces its validity and practical use. As the authors note, “As a health maintenance organization, our mandate is to help our patients live longer and better. Using the MEFI as part of routine primary care may help us achieve this goal.” By focusing on early intervention for those most at risk, MEFI could significantly impact health maintenance costs and enable clinicians to allocate resources more effectively. This new EFI version positions Israel at the forefront of frailty research, and its success could pave the way for other countries with similar healthcare systems to adopt or adapt the approach. Future steps include integrating MEFI as a routine part of primary care in Israel to ensure timely intervention and support as patients age. In summary, MEFI is a powerful tool that empowers Israel’s healthcare system to identify and support older adults most in need, marking a significant advancement in caring for an aging population.

  • How AI and Longevity Biotechnology are Revolutionizing Healthcare for Healthier, Longer Lives

    How AI and Longevity Biotechnology are Revolutionizing Healthcare for Healthier, Longer Lives
    2024/11/06
    Imagine a future where we not only live longer but stay healthy throughout those extra years. Thanks to recent breakthroughs in biotechnology and artificial intelligence (AI) in healthcare, this vision is closer to becoming a reality. Advancements in Aging Research Aging research has made significant progress in recent years by combining disciplines like biology, technology, and medicine to tackle the challenges of extending healthspans and reducing age-related diseases. While people today live longer than ever before, extending our “healthspan”—the years we stay active and illness-free—remains challenging. AI and health biomarkers (biological indicators of our body’s condition) are now key tools in the pursuit of longer, healthier lives. In a recent paper, led by corresponding authors Yu-Xuan Lyu from Southern University of Science and Technology Shenzhen; Alex Zhavoronkov from Insilico Medicine AI Limited, Masdar City, Abu Dhabi; Morten Scheibye-Knudsen and Daniela Bakula from the Center for Healthy Aging, University of Copenhagen, along with numerous other collaborators, the transformative potential of AI in aging research was explored. The research paper, titled “Longevity biotechnology: bridging AI, biomarkers, geroscience and clinical applications for healthy longevity,” was published as the cover paper in Aging’s Volume 16, Issue 20.
