Cachectic cancer patients have a reduced tolerance to antineoplastic therapies and often succumb to premature death from the wasting of respiratory and cardiac muscles. Since there are no available treatments for cachexia, it is imperative to understand the mechanisms that drive cachexia in order to devise effective strategies to treat it. Although 25% of metastatic breast cancer patients develop symptoms of muscle wasting, mechanistic studies of breast cancer cachexia have been hampered by a lack of experimental models. Using tumor cells deficient for BARD1, a subunit of the BRCA1\/BARD1 tumor suppressor complex, we have developed a new orthotopic model of triple\u2010negative breast cancer that spontaneously metastasizes to the lung and leads to systemic muscle deterioration. We show that expression of the metal\u2010ion transporter,\n                    <jats:italic>Zip14<\/jats:italic>\n                    , is markedly upregulated in cachectic muscles from these mice and is associated with elevated intramuscular zinc and iron levels.

Our study provides a unique model for studying breast cancer cachexia and identifies a potential therapeutic target for its treatment.\n
