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...
متن کاملRegulation of proliferating cell nuclear antigen ubiquitination in mammalian cells.
After exposure to DNA-damaging agents that block the progress of the replication fork, monoubiquitination of proliferating cell nuclear antigen (PCNA) mediates the switch from replicative to translesion synthesis DNA polymerases. We show that in human cells, PCNA is monoubiquitinated in response to methyl methanesulfonate and mitomycin C, as well as UV light, albeit with different kinetics, but...
متن کاملPrognostic value of proliferating cell nuclear antigen in gastric carcinoma.
A new monoclonal antibody to proliferating cell nuclear antigen (PCNA), PC10, which can be used on routinely processed tissue, was applied to 93 cases of gastric carcinoma. Significant intra-tumoural variation in staining occurred. In addition to a PCNA index (percentage of positive cells per 1000 tumour cells), a semiquantitative PCNA grading system was devised, based on estimates of less than...
متن کاملProliferating cell nuclear antigen (PCNA): a dancer with many partners.
Proliferating cell nuclear antigen (PCNA) was originally characterised as a DNA sliding clamp for replicative DNA polymerases and as an essential component of the eukaryotic chromosomal DNA replisome. Subsequent studies, however, have revealed its striking ability to interact with multiple partners, which are involved in several metabolic pathways, including Okazaki fragment processing, DNA rep...
متن کاملAssociation of proliferating cell nuclear antigen with cyclin-dependent kinases and cyclins in normal and transformed human T lymphocytes.
The proliferating cell nuclear antigen (PCNA) is an auxiliary protein of DNA polymerase delta and appears to be needed for both DNA synthesis and DNA repair. It is present in low amount in resting normal human T lymphocytes and, upon mitogenic stimulation with phorbol dibutyrate and ionomycin, begins to increase in mid-G1 phase, approximately 12 to 15 hours before entry into S phase. PCNA conti...
