Project description:Cancer cachexia is a metabolic syndrome with alterations in gene expression profile that consequently lead to skeletal muscle wasting. Here, we used RNA sequencing to analyze the mRNA expression profile in the tibialis anterior muscles of the Lewis lung carcinoma (LLC) model of cancer cachexia.

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.
