For example, Liu et al. suggested that lncRNA XIST/miR-34a axis modulates thyroid cancer proliferation and growth by MET-PI3K-AKT signaling [21]; lncRNA XLOC_ 006390 was found to facilitate cervical cancer tumorigenesis and metastasis as a ceRNA against miR-331-3p and miR-338-3p [22]; Huang et al. found that H19 promoted non-small-cell lung cancer development by STAT3 signaling via sponging miR-17 [23]. Here, XIST is linked to thyroid gland carcinoma.
