For instance, promoter regions of Human kallikrein 2(KLK2) in prostate, Apolipoprotein A1 (APOA1) in liver, NK6 homeobox 3 (NKX6.3) in stomach, paired box gene-8 (PAX-8) in kidney, and Surfactant Protein B (SFTPB) in lung cancers were among the selected markers from our pipeline (Fig. S4). Here, NKX6-3 is linked to lung cancer.
