Abstract Background Growing evidence has implicated core-binding factor beta (Cbfb) as a contributor to osteoblast differentiation, which plays key role in fracture healing. Herein, we aimed assess whether Cbfb affects differentiation after fibula fracture. Methods Initially, established conditional knockout mouse model for subsequent studies. Immunohistochemical staining was conducted detect t...

PURPOSE Recent production of a monoclonal antibody, PC10, against proliferating cell nuclear antigen (PCNA) makes it possible to evaluate cell cycling in formalin-fixed tissues. In this study, the authors quantitatively evaluated the relationship between PCNA expression and two other measures of cell cycling, bromodeoxyuridine labeling index (BrdU LI) and mitotic index (MI), in archival uveal m...

Proliferating cell nuclear antigen (PCNA) forms a trimeric ring that associates with and influences the activity of many proteins participating in DNA metabolic processes and cell cycle progression. Previously, an uncharacterized small protein, encoded by TK0808 in the archaeon Thermococcus kodakarensis, was shown to stably interact with PCNA in vivo. Here, we show that this protein, designated...

Inheritance requires genome duplication, reproduction of chromatin and its epigenetic information, mechanisms to ensure genome integrity, and faithful transmission of the information to progeny. Proliferating cell nuclear antigen (PCNA)-a cofactor of DNA polymerases that encircles DNA-orchestrates several of these functions by recruiting crucial players to the replication fork. Remarkably, many...

Proliferation, migration, and the phenotypic switch of vascular smooth muscle cells (VSMCs) play an important role in remodeling induced by hypertension. Astragaloside IV (AS-IV), active ingredient Astragalus membranaceus, has been shown to exert a beneficial cardiovascular disease. The present study aimed investigate mechanism responsible for protective effects AS-IV on hypertension-induced re...

Numerous proteins, many essential for the DNA replication machinery, interact with proliferating cell nuclear antigen (PCNA) through the PCNA-interacting peptide (PIP) sequence called the PIP box. We have previously shown that the oxidative demethylase human AlkB homologue 2 (hABH2) colocalizes with PCNA in replication foci. In this study, we show that hABH2 interacts with a posttranslationally...
