During mitosis, histone deacetylase 2 (HDAC2) becomes highly phosphorylated through the action of CK2, and HDAC1 and 2 are displaced from mitotic chromosomes. HDAC1 and 2 are components of corepressor complexes, which function with lysine acetyltransferases to catalyze dynamic protein acetylation and regulate gene expression. In this study, we show ...

Cardiomyopathies are still the first cause of death in the world. The identification of resident stem cells, comprising those derived from sub-endocardial stroma, suggests the possible self regeneration of the heart under autocrine/paracrine modulation in the cardiac microenvironment. Nevertheless, because of the limited in vivo regeneration potential of damaged cardiac ...

BACKGROUND AND OBJECTIVE: Local host-modulation therapy is an emerging approach to prevent disease progression in sites with moderate periodontitis. The combination of simvastatin and alendronate would be an intriguing host-modulatory strategy because of the bone-anabolic properties of simvastatin and the antiresorptive/bone-targeting characteristics of alendronate. The objective of this study was ...

Background: Dual anti-platelet therapy including clopidogrel or prasugrel is standard of care for patients receiving stents. Prasugrel has quicker onset so it can be loaded later than clopidogrel with greater efficacy. However, prasugrel is much more expensive than clopidogrel. Objectives: To describe the incidence of 30-day death from cardiovascular causes, ...

Liver transplantation (LT) provides optimal long-term disease-free survival for hepatocellular carcinoma (HCC). High pre-LT alpha-fetoprotein (AFP) has been associated with HCC recurrence, but it is unclear whether a drop in AFP or locoregional therapy impacts survival/recurrence after LT. LT-recipients transplanted for HCC in three centers (UNOS Region 6) were reviewed ...

Activated oncogenes restrict cell proliferation and transformation by triggering a DNA damage-dependent senescence checkpoint in response to DNA hyper-replication. Here we show that loss of the p16(INK) (4a) cyclin dependent kinase inhibitor and melanoma tumour suppressor facilitates a DNA damage response after a hyper-replicative phase in human melanocytes. Unlike cells ...
