The NAC domain was originally characterized from consensus sequences from petunia NAM and from Arabidopsis ATAF1, ATAF2, and CUC2. Genes containing the NAC domain (NAC family genes) are plant-specific transcriptional regulators and are expressed in various developmental stages and tissues. We performed a comprehensive analysis of NAC family genes in Oryza(More)
We have developed a highly sensitive and high-throughput method for the simultaneous analysis of 43 molecular species of cytokinins, auxins, ABA and gibberellins. This method consists of an automatic liquid handling system for solid phase extraction and ultra-performance liquid chromatography (UPLC) coupled with a tandem quadrupole mass spectrometer(More)
Chediak-Higashi syndrome (CHS) is a rare autosomal recessive disorder characterized by severe immunologic defects, reduced pigmentation, bleeding tendency, and progressive neurological dysfunction. Most patients present in early childhood and die unless treated by bone marrow transplantation. About 10-15% of patients exhibit a much milder clinical phenotype(More)
We have performed an in situ test of the iron limitation hypothesis in the subarctic North Pacific Ocean. A single enrichment of dissolved iron caused a large increase in phytoplankton standing stock and decreases in macronutrients and dissolved carbon dioxide. The dominant phytoplankton species shifted after the iron addition from pennate diatoms to a(More)
BACKGROUND We investigated whether the improvement of cardiac function and remodeling after myocardial infarction (MI) by granulocyte colony-stimulating factor (G-CSF) relates to acceleration of the healing process, in addition to myocardial regeneration. METHODS AND RESULTS In a 30-minute coronary occlusion and reperfusion rabbit model, saline (S) or 10(More)
OBJECTIVE Synovial mesenchymal stem cells (MSCs) are a promising cell source for cartilage regeneration due to their high chondrogenic potential. For clinical safety, autologous human serum should be used instead of fetal bovine serum (FBS). We undertook this study to compare the 2 types of serum for their enhancement of the proliferation and chondrogenic(More)
Sirtuin 1 (SIRT1) is a longevity gene that protects cells against oxidative and genotoxic stress. This study aimed to investigate the associations of SIRT1 gene single nucleotide polymorphisms (SNPs), rs7895833, rs7069102, and rs2273773, with various laboratory data in 1279 Japanese health checkup examinees. The genotyping was performed using a polymerase(More)
Fluorescent acceptors have been immobilized on nanoparticulate quantum dots (QDs), which serve in turn as their FRET donors. The broad excitation and narrow emission bands of QDs mark them as having excellent potential as donors for FRET and, in principle, differently colored QDs could be excited simultaneously. The present work describes the preparation(More)
To determine the nature of intracellular Mg2+ stores and Mg2+ release mechanisms in differentiated PC12 cells, Mg2+ and Ca2+ mobilizations were measured simultaneously in living cells with KMG-104, a fluorescent Mg2+ indicator, and fura-2, respectively. Treatment with the mitochondrial uncoupler, carbonyl cyanide p-(trifluoromethoxy) phenylhydrazone (FCCP),(More)
Gout based on hyperuricemia is a common disease with a genetic predisposition, which causes acute arthritis. The ABCG2/BCRP gene, located in a gout-susceptibility locus on chromosome 4q, has been identified by recent genome-wide association studies of serum uric acid concentrations and gout. Urate transport assays demonstrated that ABCG2 is a high-capacity(More)
