The B-subunits associated with the replicative DNA polymerases are conserved from Archaea to humans, whereas the corresponding catalytic subunits are not related. The latter belong to the B and D DNA polymerase families in eukaryotes and archaea, respectively. Sequence analysis places the B-subunits within the calcineurin-like phosphoesterase superfamily.(More)
OBJECTIVE Human resistin has been linked to several inflammatory diseases such as atherosclerosis. This study aimed to clarify the expression of resistin in different inflammatory cells and its effect on endothelial cells. RESULTS In this study, RNA and protein expression of resistin were detected in human primary neutrophils, monocytes, and T cells as(More)
The effects of estrogen replacement therapy (ERT) to cardiovascular disease risk are still unclear. Low adiponectin and high resistin plasma concentrations are reported to be associated with atherosclerosis. However, it is not known how ERT affects plasma adiponectin and resistin concentrations. Seventy-three hysterectomized, nondiabetic, postmenopausal(More)
Emerging evidence indicates the potential involvement of ghrelin, an endogenous ligand for the growth hormone secretagogue receptor, in low-grade inflammatory diseases such as obesity and atherosclerosis. The goal of the present study was to use cell culture models to investigate the influences of ghrelin and obestatin in processes participating in(More)
Human DNA polymerase epsilon is composed of a 261 kDa catalytic polypeptide and a 55 kDa small subunit of unknown function. cDNAs encoding the small subunit of human and mouse DNA polymerase epsilon were cloned. The predicted polypeptides have molecular masses of 59.469 and 59.319 kDa respectively and they are 90% identical. The human and mouse polypeptides(More)
BACKGROUND Resistin is a peptide hormone secreted mainly from human monocytes and macrophages. It has an unclear association with the metabolic syndrome, which is a cluster of cardiovascular risk factors such as glucose intolerance, central obesity, insulin resistance, dyslipidemia, and hypertension. We examined the association of resistin with metabolic(More)
BACKGROUND AND AIMS Most gene expression studies examining the effect of obesity and weight loss have been performed using adipose tissue. However, the liver also plays a central role in maintaining energy balance. We wanted to study the effects of a hypocaloric diet on overall hepatic gene expression and metabolic risk factors. METHODS AND RESULTS The(More)
It has been proposed that fetal exposure to environmental stressors, such as undernutrition, during critical periods of development may lead to adaptations that permanently change the structure and function of the body. These adaptations may be important for immediate survival during fetal development, but can predispose to disease in later life. We(More)
The B-subunits of replicative DNA polymerases from Archaea to humans belong to the same protein family, suggesting that they share a common fundamental function. We report here the gene structure for the B-subunit of human DNA polymerase epsilon (POLE2), whose expression and transcriptional regulation is typical for replication proteins with some unique(More)
