BUFFALO, NY- June 17, 2024 – A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 11, entitled, “Mitophagy and cancer: role of BNIP3/BNIP3L as energetic drivers of stemness features, ATP production, proliferation, and cell migration.” Mitophagy is a selective form of autophagy which permits the removal of dysfunctional or excess mitochondria. This occurs as an adaptative response to physiological stressors, such as hypoxia, nutrient deprivation, or DNA damage. Mitophagy is promoted by specific mitochondrial outer membrane receptors, among which are BNIP3 and BNIP3L. The role of mitophagy in cancer is being widely studied, and more specifically in the maintenance of cancer stem cell (CSC) properties, such as self-renewal. Given that CSCs are responsible for treatment failure and metastatic capacity, targeting mitophagy could be an interesting approach for CSC elimination. In this new study, researchers Marta Mauro-Lizcano, Federica Sotgia, and Michael P. Lisanti from the University of Salford describe a new model system to enrich sub-populations of cancer cells with high basal levels of mitophagy, based on the functional transcriptional activity of BNIP3 and BNIP3L. “Briefly, we employed a BNIP3(L)-promoter-eGFP-reporter system to isolate cancer cells with high BNIP3/BNIP3L transcriptional activity by flow cytometry (FACS).” The model was validated by using complementary lysosomal and mitophagy-specific probes, as well as the mitochondrially-targeted red fluorescent protein (RFP), namely mt-Keima. High BNIP3/BNIP3L transcriptional activity was accompanied by increases in i) BNIP3/BNIP3L protein levels, ii) lysosomal mass, and iii) basal mitophagy activity. Furthermore, cancer cells with increased BNIP3/BNIP3L transcriptional activity exhibited CSC features, such as greater mammosphere-forming ability and high CD44 levels. “To further explore the model, we also analysed other stemness characteristics in MCF7 and MDA-MB-231 breast cancer cell lines, directly demonstrating that BNIP3(L)-high cells were more metabolically active, proliferative, migratory, and drug-resistant, with elevated anti-oxidant capacity. Therefore, high levels of basal mitophagy appear to enhance CSC features.” DOI - https://doi.org/10.18632/aging.205939 Corresponding authors - Federica Sotgia - fsotgia@gmail.com, and Michael P.

Werner syndrome (WS) is a rare genetic disorder marked by the premature onset of features typically associated with normal aging. This autosomal recessive condition manifests in individuals who generally develop normally until adolescence. As the syndrome progresses, affected individuals are predisposed to age-related diseases much earlier in life. These conditions include cataracts, type 2 diabetes, atherosclerosis, osteoporosis, and various cancers. The underlying cause of Werner syndrome is believed to be mutations in the WRN gene, which encodes a RecQ helicase crucial for DNA repair and replication. Despite the accelerated aging, cognitive function remains unaffected in individuals with WS, providing a unique model for studying the mechanisms of aging and exploring potential therapeutic interventions. Although extensive research has been conducted, the precise mechanisms underlying these effects remain elusive. On May 24, 2024, researchers Lucie Aumailley, Marie Julie Dubois, André Marette, and Michel Lebel from Université Laval published research paper chosen as the cover of Aging’s Volume 16, Issue 10, entitled, “Integrated liver and serum proteomics uncover sexual dimorphism and alteration of several immune response proteins in an aging Werner syndrome mouse model.” Recognizing the limitations of traditional investigative approaches, Aumailley et al. utilized advanced proteomics in their study. Proteomics allows the simultaneous identification and quantification of hundreds of proteins, providing a comprehensive analysis of liver and serum proteome profiles from wild-type and WRN mutant mice at different ages to uncover biological processes influenced by age and genotype.

BUFFALO, NY- June 12, 2024 – A new review paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 10, entitled, “Peripheral vascular dysfunction and the aging brain.” Aging is the greatest non-modifiable risk factor for most diseases, including cardiovascular diseases (CVD), which remain the leading cause of mortality worldwide. In their new review, researchers Devin Wahl and Zachary S. Clayton from Colorado State University and the University of Colorado note that robust evidence indicates that CVD are a strong determinant for reduced brain health and all-cause dementia with advancing age. “CVD are also closely linked with peripheral and cerebral vascular dysfunction, common contributors to the development and progression of all types of dementia, that are largely driven by excessive levels of oxidative stress (e.g., reactive oxygen species [ROS]).” Emerging evidence suggests that several fundamental aging mechanisms (e.g., “hallmarks” of aging), including chronic low-grade inflammation, mitochondrial dysfunction, cellular senescence and deregulated nutrient sensing contribute to excessive ROS production and are common to both peripheral and cerebral vascular dysfunction. Therefore, targeting these mechanisms to reduce ROS-related oxidative stress and improve peripheral and/or cerebral vascular function may be a promising strategy to reduce dementia risk with aging. Investigating how certain lifestyle strategies (e.g., aerobic exercise and diet modulation) and/or select pharmacological agents (natural and synthetic) intersect with aging “hallmarks” to promote peripheral and/or cerebral vascular health represent a viable option for reducing dementia risk with aging. “Therefore, the primary purpose of this review is to explore mechanistic links among peripheral vascular dysfunction, cerebral vascular dysfunction, and reduced brain health with aging. Such insight and assessments of non-invasive measures of peripheral and cerebral vascular health with aging might provide a new approach for assessing dementia risk in older adults.” DOI - https://doi.org/10.18632/aging.205877 Corresponding authors - Devin Wahl - devin.wahl@colostate.edu, and Zachary S.

BUFFALO, NY- June 11, 2024 – A new editorial paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 10, entitled, “CCR4-NOT complex in stress resistance and longevity in C. elegans.” The ability to mount an adaptive response to environmental stress is crucial in organismal survival and overall fitness. In the context of aging, many genes that mediate resistance to stressors are also important in longevity, and aging has been shown to cause a decline in stress resistance. In their new editorial, researchers Cheng-Wei Wu and Hadi Tabarraei from the University of Saskatchewan wrote that recently, during a screening for genes that are required for the transcriptional response to heavy metal and oxidative stress in C. elegans, they found that depletion of subunits within the evolutionarily conserved CCR4-NOT protein complex compromises stress resistance and decreases lifespan. “The CCR4-NOT (Carbon Catabolite Repression 4 – Negative On TATA-less) is a multi-protein complex tasked with regulating RNA metabolism across multiple steps including mRNA decay, transcription initiation and elongation, mRNA quality control and export, and mRNA translatability (reviewed in [3]).” Studies in yeast have shown that CCR4-NOT is required for transcriptional elongation of stress responsive genes and that loss of function mutants of this protein complex have increased sensitivity to replication stress caused by DNA damaging agents [4, 5]. An expansive role for the CCR4-NOT complex in stress-induced transcriptional programming was demonstrated in C. elegans via whole-transcriptome sequencing analysis [2]. “Together, while the CCR4-NOT complex has been extensively studied for the past 3 decades, new studies in the model organism C. elegans have revealed an important new role for this protein complex in regulating normal aging as well as a requirement for many well-characterized and evolutionarily conserved pro-longevity pathways including reduced insulin signaling, mitochondrial suppression, enhanced stress response, and dietary restriction.” DOI - https://doi.org/10.18632/aging.205918 Corresponding author - Cheng-Wei Wu - michael.wu@usask.ca Video short - https://www.youtube.com/watch?v=UFi7Dq5JXJ4 Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.205918 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - aging, oxidative stress, C. elegans, CCR4-NOT About Aging-US Aging publishes research papers in all fields of aging research, including but not limited to aging processes (from yeast to mammals), cellular senescence, age-related diseases (such as cancer and Alzheimer’s disease) and their prevention and treatment, anti-aging strategies and drug development, and, importantly, the role of signal transduction pathways in aging (such as mTOR) and potential approaches to modulate these signaling pathways to extend lifespan.

BUFFALO, NY- June 11, 2024 – The Ride for Roswell is one of the nation’s largest cycling events—hosted by Roswell Park Comprehensive Cancer Center—to raise awareness and funds for cancer research and patient care. This charity bike ride, based out of Buffalo, New York, has brought people together for 28 years to celebrate cancer survivors, pay tribute to lives that have been lost, and to work together to support research and find a cure. THE ORIGIN OF THE RIDE The Ride for Roswell started in 1989 when Mitch Flynn, owner of the advertising agency Flynn & Friends, met Katherine Gioia. Katherine was a four-year-old patient battling a rare form of cancer. After Katherine’s death (less than a year after her diagnosis), Katherine’s mother, Anne Gioia, and aunt, Donna Gioia, founded the Roswell Park Alliance Foundation in her memory to raise money for cancer research and treatment. On June 29, 1996, Mitch and Alliance Foundation staff launched the first Ride for Roswell. In the 28 years since then, thanks to over 135,000 riders and thousands of volunteers, the Ride for Roswell has raised over $72 million to fund cancer research. The event has become one of the largest charity rides in the United States. THIS YEAR This year, Ride Day is on Saturday, June 22, 2024, and will once again begin at the University at Buffalo North Campus. There are nine routes to choose from, ranging from five to 100 mile distances. All riders are encouraged to check in on the Thursday or Friday before Ride Day. Learn more about The Ride, check in, and routes: https://www.rideforroswell.org/routes/ JOIN A TEAM: TEAM OPEN ACCESS Impact Journals has been a part of this event since 2018 and continues to sponsor captain Sergei Kurenov’s peloton, Team Open Access.

BUFFALO, NY- June 10, 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 10, entitled, “Relationships of depression and antidepressant use with epigenetic age acceleration and all-cause mortality among postmenopausal women.” In this new study, researchers May A. Beydoun, Hind A. Beydoun, Jason Ashe, Michael F. Georgescu, Steve Horvath, Ake Lu, Anthony S. Zannas, Aladdin H. Shadyab, Su Yon Jung, Sylvia Wassertheil-Smoller, Ramon Casanova, Alan B. Zonderman, and Robert L. Brunner from the National Institute on Aging, U.S. Department of Veterans Affairs (Washington, DC), University of Texas Health Science Center at Houston, University of California Los Angeles, University of North Carolina at Chapel Hill, University of California San Diego, Albert Einstein College of Medicine, Wake Forest University School of Medicine, and University of Nevada Reno investigated relations of depressive symptoms, antidepressant use, and epigenetic age acceleration with all-cause mortality risk among postmenopausal women. “Frequently under-recognized depression is a major contributor to the Global Burden of Diseases [1, 2] while being the most prevalent mental illness among geriatric populations [2].” Data were analyzed from ≤1,900 participants in the Women's Health Initiative study testing four-way decomposition models. After a median 20.4y follow-up, 1,161 deaths occurred. Approximately 11% had elevated depressive symptoms (EDS+), 7% were taking antidepressant medication at baseline (ANTIDEP+), while 16.5% fell into either category (EDS_ANTIDEP+). Baseline ANTIDEP+, longitudinal transition into ANTIDEP+ and accelerated epigenetic aging directly predicted increased mortality risk. GrimAge DNA methylation age acceleration (AgeAccelGrim) partially mediated total effects of baseline ANTIDEP+ and EDS_ANTIDEP+ on all-cause mortality risk in socio-demographic factors-adjusted models (Pure Indirect Effect >0, P < 0.05; Total Effect >0, P < 0.05). Thus, higher AgeAccelGrim partially explained the relationship between antidepressant use and increased all-cause mortality risk, though only prior to controlling for lifestyle and health-related factors. “Antidepressant use and epigenetic age acceleration independently predicted increased all-cause mortality risk. Further studies are needed in varying populations.” DOI - https://doi.org/10.18632/aging.205868 Corresponding author - May A.

BUFFALO, NY- June 5, 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 10, entitled, “Serine racemase expression profile in the prefrontal cortex and hippocampal subregions during aging in male and female rats.” Aging is associated with a decrease in N-methyl-D-aspartate (NMDA) receptor function, which is critical for maintaining synaptic plasticity, learning, and memory. Activation of the NMDA receptor requires binding of the neurotransmitter glutamate and also the presence of co-agonist D-serine at the glycine site. The enzymatic conversion of L-serine to D-serine is facilitated by the enzyme serine racemase (SR). Subsequently, SR plays a pivotal role in regulating NMDA receptor activity, thereby impacting synaptic plasticity and memory processes in the central nervous system. As such, age-related changes in the expression of SR could contribute to decreased NMDA receptor function. However, age-associated changes in SR expression levels in the medial and lateral prefrontal cortex (mPFC, lPFC), and in the dorsal hippocampal subfields, CA1, CA3, and dentate gyrus (DG), have not been thoroughly elucidated. In this new study, researchers Linda Bean, Prodip K. Bose, Asha Rani, and Ashok Kumar from Indiana University School of Medicine, North Florida/South Georgia Veterans Health System, and the University of Florida aimed to determine the SR expression profile, including protein levels and mRNA, for these regions in aged and young male and female Fischer-344 rats. Their results demonstrate a significant reduction in SR expression levels in the mPFC and all hippocampal subfields of aged rats compared to young rats. No sex differences were observed in the expression of SR. “These findings suggest that the decrease in SR levels may play a role in the age-associated reduction of NMDA receptor function in brain regions crucial for cognitive function and synaptic plasticity.” DOI - https://doi.org/10.18632/aging.205841 Corresponding author - Ashok Kumar - kash@ufl.edu Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.205841 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - aging, serine racemase, hippocampus, medial prefrontal cortex (mPFC), NMDA receptor About Aging-US Aging publishes research papers in all fields of aging research, including but not limited to aging processes (from yeast to mammals), cellular senescence, age-related diseases (such as cancer and Alzheimer’s disease) and their prevention and treatment, anti-aging strategies and drug development, and, importantly, the role of signal transduction pathways in aging (such as mTOR) and potential approaches to modulate these signaling pathways to extend lifespan.

BUFFALO, NY- June 3, 2024 – A new research paper was published on the cover of Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 10, entitled, “Integrated liver and serum proteomics uncover sexual dimorphism and alteration of several immune response proteins in an aging Werner syndrome mouse model.” Werner syndrome (WS) is a progeroid disorder caused by mutations in a protein containing both a DNA exonuclease and DNA helicase domains. Previous studies indicated that males lacking the helicase domain of the Wrn protein orthologue exhibited hepatic transcriptomic and metabolic alterations. In this new study, researchers Lucie Aumailley, Marie Julie Dubois, André Marette, and Michel Lebel from Université Laval used a label-free liquid chromatography-tandem mass spectrometry approach to uncover proteins abundance associated with specific biological processes that differed depending on the age (four or ten months) and/or the genotype (wild type or Wrn mutant) in the serum and liver of mice. Principal component analysis of the proteomic data from both serum and hepatic tissue revealed a sexual dimorphism regardless of the age and the genotype of the mice. “Moreover, although all Wrn mutant mice exhibited fatty liver by the age of ten months, a significant age and genotype dependent enrichment of proteins involved in lipid and fatty acid metabolic processes were uncovered only in males.” Also, a genotype dependent increase in serum oxidant detoxification processes was observed in the serum of Wrn mutant males. Despite these sexual differences, several aspects of the immune system were affected in both females and males. Finally, an increase of specific immunoglobulin molecules was common in the liver and serum of both older Wrn mutant females and males. “Such results suggest that specific immunoglobulin variants maybe associated with fatty liver progression in WS.” DOI - https://doi.org/10.18632/aging.205866 Corresponding author - Michel Lebel - michel.lebel@crchudequebec.ulaval.ca Sign up for free Altmetric alerts about this article - https://aging.altmetric.com/details/email_updates?id=10.18632%2Faging.205866 Subscribe for free publication alerts from Aging - https://www.aging-us.com/subscribe-to-toc-alerts Keywords - aging, proteomics, Werner syndrome, fatty liver, sexual dimorphism, immunoglobulins About Aging-US Aging publishes research papers in all fields of aging research, including but not limited to aging processes (from yeast to mammals), cellular senescence, age-related diseases (such as cancer and Alzheimer’s disease) and their prevention and treatment, anti-aging strategies and drug development, and, importantly, the role of signal transduction pathways in aging (such as mTOR) and potential approaches to modulate these signaling pathways to extend lifespan.

BUFFALO, NY- May 22, 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 9, entitled, “Cell type-dependent modulation of senescence features using Weo electrolyzed water.” Electrolyzed-reduced water has powerful antioxidant properties with constituents that scavenge reactive oxygen species (ROS), which are known to be produced by several intrinsic and extrinsic processes. When there is an imbalance between ROS production and antioxidant defenses, oxidative stress occurs. Persistent oxidative stress leads to cellular senescence, an important hallmark of aging, and is involved in several age-related conditions and illnesses. In this new study, researchers Brenda L. Court-Vazquez, Shirley A. Arroyo-Vizcarrondo, Jonathan A. Poli, Lara Nyman, Kelly Halderman, Anthony Ginter, and Pierre-Yves Desprez from Weo LLC and California Pacific Medical Center investigated whether Weo electrolyzed water (WEW) could modulate the phenotype of senescent cells. “The focus of this study was to utilize two different cell types, human normal fibroblasts and human breast cancer cells, to investigate the impact of Weo electrolyzed water (WEW) on markers of cellular senescence, inflammation, and stress response genes.” The researchers compared normal human lung fibroblasts (BJ) and breast cancer cells (T47D) treated with hydrogen peroxide (H2O2) to induce senescence. They assessed the molecular impact of WEW on markers of cellular senescence, senescence-associated secretory phenotype (SASP) factors, and stress response genes. Treatment with WEW modulated markers of cellular senescence, such as the senescence-associated β-galactosidase (SA-β-gal) activity, EdU incorporation and p21 expression, similarly in both cell types. However, WEW modulated the expression of SASP factors and stress response genes in a cell type-dependent and opposite fashion, significantly decreasing them in BJ cells, while stimulating their expression in T47D cells. Reduction in the expression of SASP factors and stress-related genes in BJ cells suggests that WEW acts as a protective factor, thereby reducing oxidative stress in normal cells, while making cancer cells more sensitive to the effects of cellular stress, thus increasing their elimination and consequently reducing their deleterious effects. “In conclusion, we have shown here that the new technology developed by Weo, WEW, could attenuate the overall process of cellular senescence in both normal BJ fibroblasts and cancer T47D cells.” DOI - https://doi.org/10.18632/aging.205789 Corresponding authors - Brenda L.

The literature cites hundreds of supposedly beneficial pharmacological and genetic interventions in model organisms: mice, rats, flies and worms, where research into physiology is routinely accompanied by lifespan data. However, when experimental animals from one article live as long as controls from another article, comparing the results of interventions across studies can yield misleading outcomes. Theoretically, all lifespan data are ripe for re-analysis: we could contrast the molecular targets and pathways across studies and help focus the further search for interventions. Alas, the results of most longevity studies are difficult to compare. This is in part because there are no clear, universally accepted standards for conducting such experiments or even for reporting such data. The situation is worsened by the fact that the authors often do not describe experimental conditions completely. As a result, works on longevity make up a set of precedents, each of which might be interesting in its own right, yet incoherent and incomparable at least for the reason that in a general context, it may indicate, for example, not prolonging the life of an average organism, but compensating for any genetic abnormalities of a particular sample or inappropriate living conditions. Here we point out specific issues and propose solutions for quality control by checking both inter- and intra-study consistency of lifespan data.
