BACKGROUND During S. pombe S-phase, initiation of DNA replication occurs at multiple sites (origins) that are enriched with AT-rich sequences, at various times. Current studies of genome-wide DNA replication profiles have focused on the DNA replication timing and origin location. However, the replication and/or firing efficiency of the individual origins on(More)
BACKGROUND DNA polymerase gamma(Pol-gamma) has been shown to be essential for maintenance of the mitochondrial genome (mtDNA) in the petite-positive budding yeast Saccharomyces cerevisiae. Budding yeast cells lacking mitochondria exhibit a slow-growing or petite-colony phenotype. Petite strains fail to grow on non-fermentable carbon sources. However, it is(More)
Constructing gene networks is one of the hot topics in the analysis of the microarray gene expression data. When combined with the output of disease gene finding, the generated gene networks will give a recommendation mechanism and an intuitive form for biologists to identify the underlying relationship among those biomarkers of the disease. In this paper,(More)
BACKGROUND The evolutionally conserved MAPK Sty1 and bZIP transcriptional activator Atf1 are known to play a pivotal role in response to the reactive oxygen species in S. pombe. However, it is unclear whether all of the H(2)O(2)-induced genes are directly regulated by the Sty1-Atf1 pathway and involved in growth fitness under H(2)O(2)-induced stress(More)
We have proposed an easy and controllable method to prepare highly ordered Au nanoarray by pulse alternating current deposition in anodic aluminum oxide template. Using the ultraviolet-visible-near-infrared region spectrophotometer, finite difference time domain, and Green function method, we experimentally and theoretically investigated the surface plasmon(More)
BACKGROUND AND PURPOSE To evaluate the time periods of Wallerian degeneration (WD) in which the diffusion parameters of ipsilateral corticalspinal tract (CST) can be used to predict the motor function outcome after brain infarction. METHODS This retrospective study classified 48 diffusion tensor imaging patients with WD along CST into four groups based on(More)
Dopaminergic (DA) neurons in the substantia nigra play crucial roles in movement control and other physiological activities. Degeneration of these neurons is closely associated with Parkinson's disease. However, the molecular identity of nigral DA neurons is not fully understood. To identify nigral DA neuron-enriched genes, we used microarrays to compare(More)
BACKGROUND DNA replication is a fundamental biological process during S phase of cell division. It is initiated from several hundreds of origins along whole chromosome with different firing efficiencies (or frequency of usage). Direct measurement of origin firing efficiency by techniques such as DNA combing are time-consuming and lack the ability to measure(More)
The recovery of liver mass is mainly mediated by proliferation of hepatocytes after 2/3 partial hepatectomy (PH) in rats. Studying the gene expression profiles of hepatocytes after 2/3 PH will be helpful to investigate the molecular mechanisms of liver regeneration (LR). We report here the first application of weighted gene co-expression network analysis(More)
High-throughput assays, such as RNA-seq, to detect differential abundance are widely used. Variable performance across statistical tests, normalizations, and conditions leads to resource wastage and reduced sensitivity. EDDA represents a first, general design tool for RNA-seq, Nanostring, and metagenomic analysis, that rationally selects tests, predicts(More)
