MIR222HG and glioblastoma: In further studies, we found that MIR222HG was expressed in GBM mainly as two transcripts, MIR222HG-201 and MIR222HG-202; the MIR222HG-201 transcript was the most highly expressed, and we thus concluded that it was the MIR222HG-201 transcript representing the role of MIR222HG (Figure 1E).
