Comprehensive bioinformatics analysis identified and validated KIT as a key gene associated with glutamine metabolism in thyroid carcinoma

Abstract The increasing incidence and mortality of thyroid cancer (THCA) exacerbates the global cancer burden. Glutamine metabolism is a hallmark metabolic feature of tumors, but its impact on the pathogenesis and progression of THCA remains unclear. Studies retrieved THCA data from TCGA and GEO databases. Cluster analysis, differential expression analysis, and weighted gene co-expression network analysis were used to identify key glutamine metabolism-related genes (GMRGs) in THCA. Identification of key genes through protein-protein interaction network construction, based on expression and
