In addition, we further analyzed the correlation between FOXD2-AS1, miR-7-5p, and TERT expression in clinical samples from TCGA, and found that FOXD2-AS1 expression levels significantly and positively correlated with TERT expression (Figure 7D), and was negatively associated with miR-7-5p in thyroid cancer tissues (Figure 7E). Here, TERT is linked to thyroid cancer.
