Comparison of the three gene lists used in the Fig. 1 allowed us to identify 70 differentially expressed HKGs that are common among the lung cancer samples such as 26S protease regulatory subunit 4 (PSMC1), ubiquitin-conjugating enzyme E2 C (UBE2C), ubiquitin-conjugating enzyme E2 D3 (UBE2D3), proteasomal non-catalytic subunit (PSMD2), ras homolog family member A (RHOA), and FYN proto-oncogene, Src family tyrosine kinase (FYN) (Fig. 2A, Table S3). Here, UBE2C is linked to lung carcinoma.
