BACKGROUND In the budding yeast, Saccharomyces cerevisiae, each DNA replication origin is associated with an autonomously replicating sequence (ARS) element. Each element contains several modules, including an essential close match to the 11 base-pair (bp) ARS consensus sequence (ACS) and two or three short (< 20 bp) stimulatory motifs, within a stretch of(More)
Some origins in eukaryotic chromosomes fire more frequently than others. In the fission yeast, Schizosaccharomyces pombe, the relative firing frequencies of the three origins clustered 4-8 kbp upstream of the ura4 gene are controlled by a replication enhancer - an element that stimulates nearby origins in a relatively position-and orientation-independent(More)
Cyclodextrins (CDs) have utility for solubilizing and stabilizing drugs. Recently CDs have been foused as therapeutics for neurodegenerative diseases. However, some CDs are toxic when administered parenterally. In this study, we investigated the effects of MβCD, a methylated form of β-CD, on endothelial cells using ECV 304 cells, a human endothelial cell(More)
Ars3002 is an efficient single-copy replication origin in the fission yeast, Schizosaccharomyces pombe. In a previous study, we tested the effects of consecutive approximately 50-bp deletions throughout ars3002 on the replication efficiency of those origins in S. pombe. Here we report the results of our use of the same approximately 50-bp deletions to test(More)
