Project description:Cancer mediated activation of the ActRIIB-ALK4/5 heterodimer by myostatin is strongly associated with muscle wasting. Progressive skeletal muscle wasting, with or without loss of adipose tissue, is observed in up to 50 per cent of all cancer patients. This multifactorial syndrome is known as cachexia, and cannot be fully reversed by conventional nutritional support. Cachexia leads to progressive functional impairment. We investigated in vitro and in vivo the efficacy of ALK4/5 receptor blockers like SB431542 in preventing muscle wasting and in this context determined muscle-related miRNA expression profiles in non-tumor bearing control mice, in SB431542 treated C26 tumor-bearing mice and in cachectic C26 tumor-bearing mice.

Project description:Cachexia is a systemic wasting syndrome that develops in many cancers and increases mortality. Despite its importance, it is largely unknown how cachexia progressively and differentially induces tissue wasting. Although cachexia occurs also in pediatric patients, little is known on the underlying mechanisms. Here, we have used pediatric melanoma xenografts to determine the progression and tissue-specific impact of juvenile cachexia on skeletal muscles, heart, white and brown adipose, liver, and brain. We find that the heart and muscles undergo wasting at early stages and are the tissues most strongly impacted transcriptionally. Beyond wasting, we identify general and organ-specific transcriptional changes that likely indicate derangement of organ/tissue function by cachexia. Moreover, also the transcriptome of tissues that do not undergo wasting, such as the brain, is profoundly remodeled by cachexia. Altogether, this study provides insight into the progression of melanoma-induced pediatric cachexia and its differential impact on distinct organ systems.
