The converse relationship of MC-let-7a-1~let-7d and MYC was only observed in HCC samples (Figure 3C, right panel, Pearson = 0.408, p = 0.004), but not in normal liver samples (Figure 3C, left panel, Pearson = −0.066, p = 0.532), normal brain samples (Figure 3D, left panel, Pearson = −060,p = 0.785) or glioblastoma samples (Figure 3D, right panel, Pearson = 0.181, p = 0.106). The gene discussed is MYC; the disease is glioblastoma.
