SLC7A2 and glioblastoma: The posttranslational modification Kcr influences the fate of neuronal stem cells by affecting the chromatin microenvironment and transcriptome remodeling.4 Yuan et al. noted that glioblastoma stem cells expressed high levels of the transporter protein solute carrier family 7 member 2 (SLC7A2) to accumulate lysine for the generation of crotonyl-coenzyme A. This involves a reprogrammed lysine catabolism.
