Figure 4From: The expression of the ubiquitin ligase subunit Cks1 in human breast cancerThe association between expression of cell cycle proteins and survival of patients with breast cancer. Relation between Cks1 (cyclin kinase subunit 1)(a), Skp2 (S-phase kinase protein 2) (b), and p27Kip1 (c) expression and overall survival (death). Analyses were constructed using the Kaplan–Meier method. Protein expression was considered low if fewer than 10% of cell nuclei were stained and high if more than 10% of nuclei were stained.Back to article page
