Submitter Supplied Information

We recently demonstrated mitochondrial degenerations precede muscle wasting in time course progression of CC. However, the extent of muscle perturbations prior to wasting in CC is unknown. Therefore, we performed global gene expression analysis in CC-induced muscle wasting to enhance understanding of intramuscular perturbations across the development of CC. Overall design: Lewis Lung Carcinoma (LLC) was injected into the hind-flank of C57BL6/J mice at 8 wks age with tumor allowed to develop for 1, 2, 3, or 4 wks and compared to PBS injected control. Muscle wasting was evident at 4 wks LLC. Animals were anesthetized using isoflourane and gastrocnemius muscles were collected for analysis. Conclusions: Current findings present novel evidence of transcriptomic shifts and altered cellular pathways in CC-induced muscle wasting.
