Figure 1. mRNA expression levels of CBXs in GBM. (A) mRNA expression levels of eight CBXs in GBM tissues and normal glial tissues from the GEPIA2. T: GBM tissues; N: normal tissues. (B) mRNA expression levels of eight CBXs in GBM tissues and normal glial tissues from the UALCAN. (C) The relative expression of eight CBX members in GBM. * p < 0.05, ** p < 0.01, *** p < 0.001.
