The alterations in carbohydrate metabolism that fuel tumor growth have been
extensively studied. However, other metabolic pathways involved in malignant
progression, demand further understanding. Here we describe a metabolic acyl-CoA
synthetase/stearoyl-CoA desaturase ACSL/SCD network causing an
epithelial-mesenchymal transition (EMT) program that promotes migration and
invasion of colon cancer cells. The mesenchymal phenotype produced upon
overexpression of these enzymes is reverted through reactivation of AMPK
signaling. Furthermore, this network expression correlates with poorer clinical
outcome of stage-II colon cancer patients. Finally, combined treatment with
chemical inhibitors of ACSL/SCD selectively decreases cancer cell viability
without reducing normal cells viability. Thus, ACSL/SCD network stimulates colon
cancer progression through conferring increased energetic capacity and invasive
and migratory properties to cancer cells, and might represent a new therapeutic
opportunity for colon cancer treatment.
