These genes were categorized as genes significantly relevant to cancer, endocrine system disorders, and organismal injury and abnormalities, including 14 upregulated genes (TTR, OGN, IGF2, IGFBP2, MGP, BMP, BMP7, BMP6, PCOLCE, LEPR, SCL22A8, DAB2, MYOC, ALDH1A2), and three downregulated genes (SLC1A1, GNAS, LPL) (Fig. 4b). This evidence concerns the gene ALDH1A2 and cancer.
