Abstract

Cancer cachexia remains a leading cause of morbidity and mortality worldwide, despite extensive research and clinical trials. The prominent clinical feature of cancer cachexia is the continuous loss of skeletal muscle that cannot be fully reversed by conventional nutritional support, and that leads to progressive functional impairment. The mechanism underlying muscle loss in patients with cachexia is poorly understood. The present study analyzed 21 cancer patients with or without cachexia, and demonstrated that mitofusin‑2 (Mfn2) was downregulated in the rectus abdominis of patients with cachexia, which was associated with body weight loss. In vitro cell experiments indicated that loss of Mfn2 was associated with atrophy of the C2C12 mouse myoblast cell line. Furthermore, in vivo animal experiments demonstrated that cachexia decreased gastrocnemius muscle mass and Mfn2 expression, and overexpression of Mfn2 in gastrocnemius muscle was able to partially attenuate cachexia‑induced gastrocnemius muscle loss. The results of the present study suggested that Mfn2 is involved in cachexia‑induced muscle loss and may serve as a potential target for therapy of cachexia.
