FASN and neoplasm: Lipids can be funneled into diacylglycerides (DAGs) and triacylglycerides (TAGs), or converted into phosphoglycerides, such as phosphatidic acid (PA), phosphatidylethanolamine (PE) and phosphatidylserine (PS), thus providing energy for tumor cells.[53] The metabolomics analysis in this study indicated that Fn infection increased the production of lipid metabolites, such as glycerophosphatide, and blood TG as well as FASN expression in the tumor.
