The key role of PDEEs including ANXA8L1, CASTOR2, CYP4B1, GTF2H2C, PSMF1, and TNS4 in pathogenesis and metastasis of NSCLC were validated based on GEPIA (Figure S2), UCSC xena (Figure S3), The Human Protein Atlas (Figure S4), cBioPortal (Figure S5), UALCAN (Figures S6 and S7) and OncoLnc (Figure S8). Here, CYP4B1 is linked to non-small cell lung carcinoma.
