We checked the combination probability of hsa_circ_0076248, mir‐181a, and SIRT1 mRNA on the website of the National Center for Biotechnology Information (NCBI; Figure 6D) and then tested whether the expression level of hsa_circ_0076248 and SIRT1 was upregulated in GBM tissue and the cell lines. The gene discussed is SIRT1; the disease is glioblastoma.
