Abstract
Doxorubicin (DOX)-induced cardiotoxicity (DIC) poses a major threat to elderly cancer patients, often leading to severe cardiac dysfunction and complicating the outcome of cancer treatment. Autophagy is one of the core mechanisms of DIC and is considered a key therapeutic target. We analyzed the status of research in the field of autophagy in DIC via bibliometric methods. A total of 292 publications related to this topic were identified and included. Furthermore, based on included publications and relevant studies in the field of geriatrics, the characteristics of autophagy in the aging heart and DIC, therapeutic strategies targeting autophagy, and challenges in clinical translation were summarized. Our review reveals that research hotspots in the field focus on how to balance the relationship between the effects of cancer treatment and cardiotoxicity, and the frontiers focus on exploring new therapeutic strategies via autophagy regulation. The autophagy ability of aging hearts is significantly reduced, which accelerates the occurrence of myocardial fibrosis, systolic dysfunction, and chronic inflammation. Autophagy has significant bidirectional regulatory effects on DIC. Additionally, the dynamic regulation of autophagy is significantly affected by dose gradients of DOX, exposure time windows, experimental models, and differences in administration methods. Drugs such as dexrazoxane and melatonin, as well as rehabilitation therapies such as aerobic training and resistance training, can regulate cardiomyocyte autophagy and have clinical translational potential. However, age heterogeneity in existing clinical studies undermines the generalizability of findings to elderly cancer patients. Future therapeutic optimization requires regimen customization based on elderly specific organ function decline patterns.
期刊介绍:
With the rise in average human life expectancy, the impact of ageing and age-related diseases on our society has become increasingly significant. Ageing research is now a focal point for numerous laboratories, encompassing leaders in genetics, molecular and cellular biology, biochemistry, and behavior. Ageing Research Reviews (ARR) serves as a cornerstone in this field, addressing emerging trends.
ARR aims to fill a substantial gap by providing critical reviews and viewpoints on evolving discoveries concerning the mechanisms of ageing and age-related diseases. The rapid progress in understanding the mechanisms controlling cellular proliferation, differentiation, and survival is unveiling new insights into the regulation of ageing. From telomerase to stem cells, and from energy to oxyradical metabolism, we are witnessing an exciting era in the multidisciplinary field of ageing research.
The journal explores the cellular and molecular foundations of interventions that extend lifespan, such as caloric restriction. It identifies the underpinnings of manipulations that extend lifespan, shedding light on novel approaches for preventing age-related diseases. ARR publishes articles on focused topics selected from the expansive field of ageing research, with a particular emphasis on the cellular and molecular mechanisms of the aging process. This includes age-related diseases like cancer, cardiovascular disease, diabetes, and neurodegenerative disorders. The journal also covers applications of basic ageing research to lifespan extension and disease prevention, offering a comprehensive platform for advancing our understanding of this critical field.
