Effect of cis-9, trans-11 conjugated linoleic acid (CLA) on the metabolism profile of breast cancer cells determined by H HR-MAS NMR spectroscopy

Conjugated linoleic acid (CLA), a fatty acid found in ruminant food products, has been associated with anticarcinogenic activity. However, its effect on cancer metabolism is unclear. In this paper we evaluated the effects of cis-9, trans-11 CLA on the metabolic profile of MCF-7 and MDA-MB-231 breast...
