Tumor tissues with low ST8SIA6-AS1 expression had high miR-125a-3p level compared to tissues with high ST8SIA6-AS1 expression (Figure 6C), and NNMT mRNA and protein levels in the ST8SIA6-AS1-depleted group were significantly lower than those in the control group (Figure 6D). This evidence concerns the gene NNMT and neoplasm.
