In order to investigate if the expression of Ki67, LAT1 and LAT2 were similar between the xenografts, the patient tumor (GBM_CHP048) used for the establishment of the xenografts and tumor specimens from a panel of 19 GBM patients, we performed qPCR and compared the NRQs relative to the gene expression in human jejunum, which was adjusted to 100. This evidence concerns the gene LAT2 and neoplasm.
