SLC6A3 and neoplasm: The genes expression levels in the model were detected by qRT-PCR, and the results showed that they were highly expressed in 20 pairs of tumor and normal tissues (UNCX, SLC6A3, AGAP2-AS1, LINC00968, PTX3 and SBSPON), while ITPRID1, DCST2, ETV3L, and ENSG00000261327 were down-regulated (Fig. 13A).
