analysis of proliferating cell nuclear antigen (pcna) associated with dna

 

 

 

 

The proliferating cell nuclear antigen (PCNA) gained considerable attention during the "first chapter" (fresh tissue analyses) of the Ki-67 immunohistochemistry. Miyachi et al. (1978) described in patients with systemic lupus erythematosus an auto-antibody that recognized the PCNA. Abstract. The level of monoubiquitinated proliferating cell nuclear antigen (PCNA) is closely linked with DNA damage bypass to protect cells from a high level of mutagenesis. As such, the comparative analysis of PCNA expression in tumors is hampered by the lack of technical and evaluation standards, some29. Bravo R, Macdonald-Bravo H.

Concomitantly, immunohistochemistry analysis of tumor tissues identified that SP1 administration at three doses significantly inhibited the in vivo cancer cell proliferation and microvessel density (MVD) formation, evidenced by a low proliferating cell nuclear antigen (PCNA) and CD34 expression Abstract Immunohistochemistry of the S phase related proliferating cell nuclear antigen (PCNA) was studied as an alternative to ex-vivo bromo-deoxyuridine (BrdU) immunohistochemistry for assessment of human colonic cell prolifera-tion.

The DNA repair endonuclease XPG binds to proliferating cell nuclear antigen (PCNA) and shares Proliferating Cell Nuclear Antigen. PCNA is an auxiliary protein for DNA polymerase that reaches maximal expression during the S phase of the cell cycle.505 Hence, PCNA has been widely used as an index of the proliferative activity of cancers.
