Abstract

Cancer-induced bone disease greatly diminishes the quality of life for patients with bone metastatic breast cancer, resulting in painful skeletal-related events including bone loss and fracture. Improved understanding of the roles of osteoblasts and osteoclasts, and how tumors alter their biology, has led to blockbuster therapies that significantly reduce skeletal-related events, but the disease remains incurable. However, emerging technologies and tools for studying the role of other stromal and immune components in controlling tumor–host interactions have begun to reveal new insights that may yield tractable therapeutic targets to further mitigate the painful effects of bone metastases. In this issue of Cancer Research, Kaur and colleagues study osteocytes, which are terminally differentiated osteoblasts and entombed within the bone matrix, from established bone metastatic breast cancer and report how the disease ages them as characterized by a senescence-associated secretory phenotype. This premature development of osteocyte senescence in turn enhances bone destruction and osteoclastogenic potential. Targeting senescent cells using senolytics suppressed bone resorption and preserved bone mass. Collectively, these findings underscore osteocyte involvement in the “vicious cycle” of bone metastasis, and targeting senescent osteocytes represents a new avenue for managing cancer-induced bone disease.See related article by Kaur et al., p. 3936

期刊介绍: Cancer Research, published by the American Association for Cancer Research (AACR), is a journal that focuses on impactful original studies, reviews, and opinion pieces relevant to the broad cancer research community. Manuscripts that present conceptual or technological advances leading to insights into cancer biology are particularly sought after. The journal also places emphasis on convergence science, which involves bridging multiple distinct areas of cancer research. With primary subsections including Cancer Biology, Cancer Immunology, Cancer Metabolism and Molecular Mechanisms, Translational Cancer Biology, Cancer Landscapes, and Convergence Science, Cancer Research has a comprehensive scope. It is published twice a month and has one volume per year, with a print ISSN of 0008-5472 and an online ISSN of 1538-7445. Cancer Research is abstracted and/or indexed in various databases and platforms, including BIOSIS Previews (R) Database, MEDLINE, Current Contents/Life Sciences, Current Contents/Clinical Medicine, Science Citation Index, Scopus, and Web of Science.
