Glutamine (Gln) is the most abundant free amino acid in the circulation. In addition to being a proteinogenic amino acid, it has multifaceted functions by serving as a nitrogen and carbon donor for the biosynthesis of essential metabolites, including nucleotides, hexosamines, and fatty acids, contributing to energy production via fueling the tricarboxylic acid cycle, regulating the redox balance, and stimulating mechanistic target of rapamycin complex 1 (mTORC1)( Altman et al., 2016; Bott et al., 2019a). Cancer cells have a high demand for Gln to support their malignant growth, which can be met by an increased expression of Gln transporter to facilitate its uptake from the tumor microenvironment (Nicklin et al., 2009). In a situation where extracellular supply of Gln is limited, such as in poorly vascularized cancers including breast cancer and pancreatic ductal adenocarcinoma(PDAC), cell autonomous Gln synthesis kicks in. In mammals, Gln can be synthesized from ammonium and glutamate (Glu), catalyzed by glutamine synthetase (GS), also named glutamate ammonium ligase (GLUL). In light of the increased demand of Gln in cancer cells,
