Similar to major biomarkers of NSCLC, including epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), and Kirsten rat sarcoma viral oncogene homolog (KRAS) (Villalobos and Wistuba, 2017), GACAT3 is upregulated in NSCLC tissues and cell lines. The gene discussed is KRAS; the disease is non-small cell lung carcinoma.
