  • Resumen

  • Cancer and aging are two sides of age-related tumorigenesis. The mission of the journal is to understand the mechanisms surrounding aging and age-related diseases, including cancer as the main cause of death in the modern aged population. The journal aims to promote 1) treatment of age-related diseases by slowing down aging, 2) validation of anti-aging drugs by treating age-related diseases, and 3) prevention of cancer by inhibiting aging. (Cancer and COVID-19 are age-related diseases.) Read about the Aging (Aging-US) Scientific Integrity Process: https://aging-us.com/scientific-integrity

    Longevity & Aging Series (S2, E2): Dr. Ming Yu and Namita Hattangady
    Oct 8 2024
    In this installment of the Longevity & Aging Series, Dr. Ming Yu and Namita Hattangady from the Fred Hutchinson Cancer Center in Seattle, join host Dr. Evgeniy Galimov to discuss a research paper they co-authored that was published as the cover for Volume 16, Issue 4 of Aging (Aging-US), entitled, “Mapping the core senescence phenotype of primary human colon fibroblasts.” DOI - https://doi.org/10.18632/aging.205577 Corresponding authors - William M. Grady - wgrady@fredhutch.org, and Ming Yu - myu@fredhutch.org Video interview - https://www.youtube.com/watch?v=eqSa7My_a7w Interview transcription - https://www.aging-us.com/interviews/longevity-aging-series-s2-e2-dr-ming-yu-and-namita-hattangady Abstract Advanced age is the largest risk factor for many diseases and several types of cancer, including colorectal cancer (CRC). Senescent cells are known to accumulate with age in various tissues, where they can modulate the surrounding tissue microenvironment through their senescence associated secretory phenotype (SASP). Recently, we showed that there is an increased number of senescent cells in the colons of CRC patients and demonstrated that senescent fibroblasts and their SASP create microniches in the colon that are conducive to CRC onset and progression. However, the composition of the SASP is heterogenous and cell-specific, and the precise senescence profile of colon fibroblasts has not been well-defined. To generate a SASP atlas of human colon fibroblasts, we induced senescence in primary human colon fibroblasts using various in vitro methods and assessed the resulting transcriptome. Using RNASequencing and further validation by quantitative RT-PCR and Luminex assays, we define and validate a ‘core senescent profile’ that might play a significant role in shaping the colon microenvironment. We also performed KEGG analysis and GO analyses to identify key pathways and biological processes that are differentially regulated in colon fibroblast senescence. These studies provide insights into potential driver proteins involved in senescence-associated diseases, like CRC, which may lead to therapies to improve overall health in the elderly and to prevent CRC.

  • Cerebral Blood Flow and Arterial Transit in Older Adults

    Cerebral Blood Flow and Arterial Transit in Older Adults
    Oct 8 2024
    BUFFALO, NY- October 8, 2024 – A new #research paper was #published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science), Volume 16, Issue 18 on September 18, 2024, entitled, “Determinants of cerebral blood flow and arterial transit time in healthy older adults.” This research paper highlights that brain health deteriorates with age, particularly in terms of cerebral blood flow (CBF) and arterial transit time (ATT), key markers of brain vascular health. This decline can impair cognitive function and limit independence in later life—an issue that will affect many as the global population continues to age rapidly. In their paper, researchers Jack Feron, Katrien Segaert, Foyzul Rahman, Sindre H. Fosstveit, Kelsey E. Joyce, Ahmed Gilani, Hilde Lohne-Seiler, Sveinung Berntsen, Karen J Mullinger, and Samuel J. E. Lucas from the University of Birmingham, University of Agder, and University of Nottingham aimed to identify modifiable determinants of CBF and ATT in healthy older adults (n = 78, aged 60–81 years). They also investigated the relationship between CBF, ATT, and cognitive function in older adults. The researchers hypothesized that markers of superior general health—such as higher cardiorespiratory fitness, handgrip strength, and grey matter volume, or lower age, BMI, and blood pressure—would be associated with greater CBF and shorter ATT. Results from multiple linear regressions revealed that a higher BMI was associated with lower global cerebral blood flow (CBF) (β = −0.35, P = 0.008) and longer global arterial transit time (ATT) (β = 0.30, P = 0.017). Additionally, global ATT increased with age (β = 0.43, P = 0.004), while higher cardiorespiratory fitness was linked to longer ATT in the parietal (β = 0.44, P = 0.004) and occipital (β = 0.45, P = 0.003) regions. However, neither global nor regional CBF or ATT were associated with processing speed, working memory, or attention. “In conclusion, preventing excessive weight gain may help attenuate age-related declines in brain vascular health.” DOI - https://doi.org/10.18632/aging.206112 Corresponding author - Jack Feron - j.feron@bham.ac.uk Video short - https://www.youtube.com/watch?v=QpS4kK273os Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.206112 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts About Aging-US The mission of the journal is to understand the mechanisms surrounding aging and age-related diseases, including cancer as the main cause of death in the modern aged population.
