Muscle and adipose transcriptome in a mouse model of cachexia induced by orthotopic pancreatic cancer, with and without tumor-derived interleukin-6 (IL-6)


ABSTRACT: Pancreatic ductal adenocarcinoma (PDAC) causes involuntary wasting of adipose and muscle tissue, also known as cachexia. Cachexia is a major cause of cancer-related deaths, particularly among patients with PDAC. Here we profiled gene expression in adipose tissue and skeletal muscle in normal/sham control mice and in mice bearing orthotopic PDAC tumors. PDAC tumors were initiated by intra-pancreatic injection of a cell line derived from the KPC (Kras-G12D;Trp-R172H;Pdx1::Cre) genetically engineered mouse model of pancreatic cancer, or by injection of the same cell line deleted for the IL6 gene using CRISPR/Cas9. KPC-IL6 knockout (ko) cells caused less adipose wasting and no muscle loss compared with KPC-wildtype (wt) cells.
