Results of proliferating nuclear antigen immunohis-tochemical studies indicate that the myoepithelial cell, rather than the epithelial cell, is the predominant proliferating element in EMC. There is no overexpression of FlER-2/neu oncogene and, from initial studies, determination of DNA ploidy offers no additional prognostic information.

Nuclear-specific proteins, such as Ki-67 (MIB-1), proliferating cell nuclear antigen (PCNA) and protein 53 have an essential role in cell proliferation and are widely accepted proliferation marker. They are present in all dividing cells of normal and tumor tissues, but absent in resting cells.

One fascinating observation is that PCNA (proliferating cell nuclear antigen) can be modified by multiple forms of ubiquitin, demonstrating that DUBs with different specificities can act at the same location on a specific substrate. PCNA can be modified by mono-ubiquitin, 63-linked polyubiquitin, or SUMO at K164 [89]. Modification of PCNA by mono- or polyubiquitin determines whether it is utilized in translesion synthesis or error-free DNA repair, respectively. SUMO modification prevents PCNA function in DNA repair and instead promotes DNA replication. It is probable that multiple DUBs, as yet unidentified, are required to regulate PCNA modification.

In a carcinogenicity study, liver cell proliferation in Wistar rats measured using immunostaining with a monoclonal antibody to proliferating cell nuclear antigen in the highest-dose group was maximal at six months of treatment (Yasuhara et al., 1995).
