MiR-101-3p promotes apoptosis of oral cancer cells by targeting BICC1 (Wang et al., 2020), induces dysfunction of vascular endothelial cell by targeting tet methylcytosine dioxygenase 2 (Chen et al., 2020), suppresses proliferation and metastasis of glioblastoma cells via targeting TRIM44 (Li et al., 2019). Here, TET2 is linked to glioblastoma.
