Moreover, IHC staining of a renal cancer tissue microarray with anti-CBX7 and anti-RNF26 antibodies demonstrated that CBX7 expression was negatively correlated with RNF26 expression in the patient specimens (Spearman correlation r = -0.349, P = 0.0318) (Fig. 5I, J). Here, RNF26 is linked to renal carcinoma.
