S (Dundee Cell Products, catalog no. DS1002) supplemented with either T3 (a 25mM stock option was ready in 100 mM NaOH), F16BP (a 100-mM stock option was prepared in McCoy’s 5A media, as well as the pH adjusted to 7.4 with NaOH or phenylalanine (an 80-mM stock remedy was ready in McCoy’s 5A media). All ligand stocks have been filtered via a 0.2-m filter. Cells have been then grown to get a further 72 h and were collected by suspension in trypsin-EDTA and counted in a hemocytometer. Ligands utilized within this study interfere with metabolic pathways (TCA and glycolysis), leading to difficulties interpreting metabolic-based proliferation assays. ACKNOWLEDGMENTS. We thank Dr. J.
