Mouse models of cancer-induced cachexia: Hind limb muscle mass and evoked force as readouts

Jourdain, Marie and Melly, Stefan and Summermatter, Serge and Hatakeyama, Shinji (2018) Mouse models of cancer-induced cachexia: Hind limb muscle mass and evoked force as readouts. Biochemical and biophysical research communications : BBRC. ISSN 1090-2104

Abstract

The majority of patients with advanced cancer suffer from cachexia, a systemic wasting syndrome, which subsequently impacts the tolerance to anti-cancer treatments, response to therapy, quality of life, and eventually, survival. Despite a high unmet medical need, there is currently no specific remedy available for an effective treatment of cachexia and its sequelae. A key feature of cachexia is the inexorable loss of skeletal muscle mass, which constitutes a main contributor to body weight loss and progressive functional impairments. Therefore, it's crucial to identify early readouts to detect and monitor the loss of muscle mass and function to initiate appropriate treatments timely.

Here, we describe experimental cancer models using mouse (syngeneic) or human (xenograft) cancer cell lines with a rapid onset of tumor growth and cachexia. These models are easier to establish, monitor and reproduce compared to the genetically engineered mouse models currently available. Moreover, we establish readouts such as hind limb muscle mass and volume, as well as evoked force and food intake measurements, to allow the evaluation of potential therapeutic agents for the early treatment of cachexia and associated impairments.
