Tumour tissues are often characterized by intense signals from fatty acids that have been widely studied to provide possible markers of tumour metabolism. We studied the effects of hyperammonia and hypoxia conditions in tumour cells, in order to provide more insight on these lipid metabolites and possible changes in their synthesis. Both hyperammonia and hypoxia induce significant increases in neutral lipid signals. Present data show that 1H NMR can be used to detect accumulation of neutral lipids due to conditions that are frequently encountered in tumour tissues pointing to a possible use as detectors of cell response to modified environment.
