Table 3.
Branched-chain amino acid removal capability of human glioma (SW1088; n = 6), glioblastoma (A172, n = 3), and neuroblastoma (SH-SY5Y, n = 6) cells from the culture media (DMEM/FBS). Concentrations of leucine, isoleucine, and valine in the media were estimated from 1H-NMR spectra by a method of external standards. Data are presented as the mean ± SEM.
