CBX8 and renal cell carcinoma: Correlation analysis of the CBXs with each other revealed significant negative correlations between CBX6 with CBX3 (ccRCC: ρ = −0.51, p = 3.36−24; pRCC: ρ = −0.38, p = 8.78−11) and CBX8 (ccRCC: −0.341, p = 4.60−11; pRCC: ρ = −0.33, p = 2.05−8), for both RCC subtypes (Figure 6).
