CST1 and neoplasm: Subsequently, the extracted 6 genes in DEGs that overlapped with the tumor-related modules including beta-1,3-N-acetylglucosaminyltransferase 3 (B3GNT3), adhering 3 (CDH3), cysteine SN (CST1), zinc finger and BTB domain containing 16 (ZBTB16), keratin 15 (KRT15), and cloth beta (KLB) were selected as the hub genes for subsequent analysis (Figure 2C).
