SLC7A11 and cancer: Glutamine plays an important role in cell proliferation, and its metabolic reprogramming often occurs in cancer cells, which manifests as increased glutamine metabolism.29 A previous article reported the prognostic significance of amino acid transporter expression (LAT1, ASCT2, and xCT) in surgically resected tongue cancer.7 In comparison, our study had the advantage of determining the expression of glutamine metabolic pathway‐related factors in OSCC.
