LncRNA XIST functioned as a ceRNA to regulate the IRS1/PI3K/Akt pathway by sponging miR-126, elevated the expression of GLUT1, and promoted glioblastoma cell viability, migration, invasion, and resistance to apoptosis (Cheng et al., 2020) (Table 1; Figure 7). The gene discussed is SLC2A1; the disease is glioblastoma.
