Research description

Human cancer develops as a localized focus of uncontrolled cell growth and subsequently progresses into systemic disease. Cancer research primarily focuses on the agents, events, and genetic alterations underlying tumor initiation, progression and metastasis. However, many cancer patients die because of cachexia, a systemic wasting disease caused by the tumor, but manifested by alterations in distant organs resulting in weight loss, fatigue, anemia, progressive atrophy of the white adipose tissue (WAT) and skeletal muscle. Systemic inflammation and metabolic dysfunction have been proposed as the major culprits in cachexia patho-physiology, but their chronological appearance and regulation remain elusive. I have recently shown that brown fat is prevalent in cachectic cancer patients (Petruzzelli M et al. Cell Metabolism 2014) and I now plan to investigate the cellular players and molecular events that drive the inflammatory response during cachexia.
