BUFFALO, NY- June 26, 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 11, entitled, “Global consensus for sarcopenia.”

In this new editorial, researchers Ben Kirk, Peggy M. Cawthon, and Alfonso J. Cruz-Jentoft from the University of Melbourne and Western Health discuss the global societal issue of skeletal muscle loss and weakness, termed Sarcopenia. Low muscle mass or low strength/function increases the susceptibility to poor outcomes such as fragility, hip fractures, disability, and low quality of life in older people [1–4]. Skeletal muscle also acts as an endocrine organ and interacts with local and distal tissues; for instance, muscle cells secrete molecules involved in bone fracture healing and the same molecules help regulate distal tissues such as the brain, heart, and kidneys [5, 6]. This may partially explain why low muscle mass is a strong predictor of disease-specific mortality (dementia, cancer, heart failure, kidney/liver disease) as well as all-cause mortality in aging [7]. 

“Until now, there has been no universal agreement on a definition for Sarcopenia.”

Previous definitions were continent- and region-specific: Asia, Europe, North America, and Australia/New Zealand [8]. These definitions were certainly important in drawing attention to, and understanding of, this muscle disease. However, these definitions led to wide estimates in disease prevalence/incidence as well as heterogeneity when comparing treatments results of randomised trials [9]. The lack of a single definition likely impacted the identification of or treatment for sarcopenia in research and clinical practice (i.e., caused confusion for scientists, physicians and health care professionals on which definition, cutpoints, and muscle assessment tools to employ). 

“To address this, the Global Leadership Initiative in Sarcopenia (GLIS) [9] was formed to create a unified global definition for use in research and clinical settings.”

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.

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.)

Aging (Aging-US)

Global Consensus for Sarcopenia

Cellular quality control mechanisms like mitophagy, a specialized form of autophagy that eliminates dysfunctional mitochondria, play a pivotal role in various physiological processes. Defects in mitophagy have been linked to neurodegeneration, heart failure, cancer, and aging.

A recent study, by researchers Marta Mauro-Lizcano, Federica Sotgia, and Michael P. Lisanti from the University of Salford, has shed light on the intricate link between mitophagy and cancer stem cells (CSCs). In this study, the researchers developed an innovative fluorescence-based approach to enrich subpopulations of cancer cells exhibiting high basal levels of mitophagy. Their findings reveal that elevated mitophagy activity enhances CSC properties, including self-renewal, ATP production, proliferation, and cell migration, underscoring the potential of targeting mitophagy as a therapeutic strategy for cancer treatment. 

On June 4, 2024, their research paper was published on the cover of Aging’s Volume 16, Issue 11, entitled, “Mitophagy and cancer: role of BNIP3/BNIP3L as energetic drivers of stemness features, ATP production, proliferation, and cell migration.”
