Second, when fatty acid-free media were supplemented with fatty acid-free albumin-complexed palmitate in order to facilitate its uptake by cancer cells, FASNlox/lox-PyMT, FASNlox/lox-HER2, or FASNlox/lox-KRAS MEFs did not form colonies in soft agar (Supplementary Fig. 4f). The gene discussed is ALB; the disease is cancer.
