  In an aging population, the decline in muscle mass and strength in combination with a high prevalence of osteoporosis and cancer leads to a multitude of clinical manifestations. In the recent years, mouse models of wasting in cancer and inflammation, including xenograft, genetic and chemically induced models, allowed to uncover several key mechanisms underlying muscle loss. These include inflammation, hormone alterations and deregulated protein degradation. Inflammation is associated with increased expression of tumor necrosis factor α (TNF-α), nuclear factor κB (NF-κB), and interleukin (IL)-6 and is therefore linked to inflammatory bowel diseases or chronic obstructive pulmonary disease (COPD). Moreover, active NF-κB signaling and IL-6 secretion commonly occurs in malignancies and cancer-induced cachexia. The ubiquitin proteasome-mediated degradation of prote.. View More»
