UV inducibility of rat proliferating cell nuclear antigen gene promoter.

Proliferating cell nuclear antigen (PCNA), also known as a cofactor of DNA polymerase delta, is required for eukaryotic cell DNA synthesis and nucleotide excision repair. Expression of PCNA gene is growth-regulated and UV inducible. In our previous study, we have observed that the rat PCNA promoter has the serum responsiveness. In this study, we demonstrate its UV inducibility in CHO.K1 cells. ...

Antisense Proliferating Cell Nuclear Antigen Oligonucleotides

We have used antisense phosphorothioate oligonucleotides to define the role played by proliferating cell nuclear antigen (PCNA) in neointimal accumulation of smooth muscle cells in a rat carotid artery injury model. The short-term extraluminal delivery of 250 nmol of antisense oligonucleotides, but not control oligonucleotides, immediately after arterial injury produces a 77% suppression of PCN...

Involvement of RFX1 protein in the regulation of the human proliferating cell nuclear antigen promoter.

The proliferating cell nuclear antigen (PCNA) is an essential eukaryotic DNA replication factor that is transcriptionally regulated by the adenovirus oncoprotein E1A 243R. Inducibility of the human PCNA promoter by E1A 243R is conferred by the cis-acting PCNA E1A-responsive element (PERE), which associates with the ATF-1, cAMP response element-binding protein (CREB), and RFX1 transcription fact...

Transcriptional activation of the human proliferating-cell nuclear antigen promoter by p53.

Proliferating-cell nuclear antigen (PCNA) is a DNA damage-inducible protein that performs an essential function in DNA replication and repair as an auxiliary factor for DNA polymerases delta and epsilon. Examination of the human PCNA promoter DNA sequence revealed a site with homology to the consensus DNA sequence bound by p53. PCNA promoter fragments with this site intact bound p53 in vitro an...

Regulation of the human proliferating cell nuclear antigen promoter by the adenovirus E1A-associated protein p107.

The adenovirus E1A 243R oncoprotein is capable of transactivating the expression of the human proliferating cell nuclear antigen (PCNA) promoter. Mutational analysis of the E1A 243R protein suggested that both its p300/CBP- and p107-binding regions are required for optimal induction of the PCNA promoter (C. Kannabiran, G. F. Morris, C. Labrie, and M. B. Mathews, J. Virol. 67:425-437, 1993). We ...
