WRKY proteins are major transcription factors involved in regulating plant growth and development. Although many studies have focused on the functional identification of WRKY genes, our knowledge concerning many areas of WRKY gene biology is limited. For example, in cotton, the phylogenetic characteristics, global expression patterns, molecular mechanisms(More)
CBF/DREB transcription factors play essential roles in plant stress signaling transduction pathway. We isolated and identified a CBF/DREB homologous gene, FeDREB1, from Fagopyrum esculentum. Protein sequence alignment and phylogenetic analyses revealed that the FeDREB1 was grouped into the DREB (A-1) lineage. Moreover, subcellular localization observations(More)
The effect of leucine on glucose-stimulated insulin secretion (GSIS) in pancreatic beta-cells is quite controversial, and mechanism involved in the effect has not been elucidated yet. Consequently, we aimed to investigate effect of leucine on GSIS and its mechanism focusing on contribution of AMP-activated protein kinase (AMPK) and pancreatic/duodenal(More)
OBJECTIVE Demethylation of CD11a and CD70 regulatory regions in CD4+ T cells contributes to the development of autoreactivity and overstimulation of autoantibodies. Because growth arrest and DNA damage-induced 45alpha (GADD45alpha) reduces epigenetic silencing of genes by removing methylation marks, this study examined whether the gadd45A gene could(More)
SQUAMOSA promoter binding protein-like (SPL) genes encode plant-specific transcription factors that are involved in many fundamental developmental processes. Certain SPL genes contain sequences complementary to miR156, a microRNA (miRNA) that plays a role in modulating plant gene expression. In this study, 30 SPL genes were identified in the reference(More)
Dilation-assisted stone extraction, also termed small endoscopic sphincterotomy (EST) plus endoscopic papillary balloon dilatation, is more efficient than EST alone for removal of large common bile duct (CBD) stones. However, whether this technique can be used for all stones is unclear. This study was designed to evaluate the efficacy and complications of(More)
Considering the obvious advantages in efficacy and price, doxorubicin (DOX) has been widely used for a range of cancers, which is usually encapsulated in various nanocarriers for drug delivery. Although effective, in most nanocarrier-based delivery systems, the drug loading capacity of DOX is rather low; this can lead to undesired systemic toxicity and(More)
Phytophthora capsici is an aggressive plant pathogen that affects solanaceous and cucurbitaceous hosts. Necrosis-inducing Phytophthora proteins (NPPs) are a group of secreted toxins found particularly in oomycetes. Several NPPs from Phytophthora species trigger plant cell death and activate host defense gene expression. We isolated 18 P. capsici NPP genes,(More)
Fluorescent carbon dots (CDs) were solvothermaly synthesized in water-glycol medium by using glucose as carbon source and then modified with polyethyleneimine (PEI) for the first time to improve fluorescence quality. The as-prepared CDs were monodispersed sphere particles with a diameter of about 7.5 nm, emitting strong fluorescence which is excitation(More)
Excess nitrogen inputs to terrestrial ecosystems via human activities have deteriorated water qualities on regional scales. Urban areas as settlements of over half global population, however, were usually not considered in the analysis of regional water pollution. Here, we used a 72-month monitoring data of water qualities in Hangzhou, China to test the(More)
