The previously established roles of the amino acid glutamine have recently been expanded to include not only protein and nucleotide synthesis, as well as contributing significantly to energy production via mitochondrial hydrolysis of glutamine to glutamate, but also the role of this molecule in the reductive carboxylation of α-ketoglutarate resulting in carbon atoms used in cell membrane biosynthesis. Additionally, glutamine participates in maintaining glutathione homeostasis as well as regulation of anabolic signaling. Given its central role in anabolic processes, glutamine is preferentially transported into human cancer cells at a significant rate as compared to normal cells. This distinction has prompted …

GBM is the most common CNS derived malignancy diagnosed each year. The median survival time to date is between 14.6 to 16.7 months for patients suffering from the disease. Clinical trials and research has yet to yield a breakthrough treatment. The invasive nature of GBM to surrounding tissue typically poses a challenge for complete surgical resection of the tumor, and radiotherapy remains a predominant treatment modality. The NHEJ pathway is main repair pathway responsible for repairing lethal radiation damage. As a result, this study used the CRISPR-Cas9 system to genetically engineer two GBM cell lines lacking expression of an essential …
