Regulation 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 کاملAntisense 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 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 expression in childhood acute leukemia.
Proliferating cell nuclear antigen (PCNA) is a 36-Kd nuclear protein, identified as the auxiliary protein of DNA polymerase delta, that is upregulated in activated proliferating cells from a variety of tissues and species, including human lymphocytes. We have examined by two-dimensional polyacrylamide gel electrophoresis the expression of PCNA in various subtypes of childhood acute leukemia and...
متن کاملTargeting cytosolic proliferating cell nuclear antigen in neutrophil-dominated inflammation
New therapeutic approaches that can accelerate neutrophil apoptosis under inflammatory conditions to enhance the resolution of inflammation are now under study. Neutrophils are deprived of proliferative capacity and have a tightly controlled lifespan to avoid their persistence at the site of injury. We have recently described that the proliferating cell nuclear antigen (PCNA), a nuclear factor ...
