We have generated 47,932 T-DNA tag lines in japonica rice using activation-tagging vectors that contain tetramerized 35S enhancer sequences. To facilitate use of those lines, we isolated the genomic sequences flanking the inserted T-DNA via inverse polymerase chain reaction. For most of the lines, we performed four sets of amplifications using two different(More)
Histamine provokes itching and is a major skin disease complaint. Histamine is known to excite a subset of sensory neurons, predominantly C-fibers. Although histamine is pruritogenic, its signaling pathways that excite sensory neurons have not been identified. Because the metabolic products of lipoxygenases (LOs) activate transient receptor potential(More)
BACKGROUND Caveolin-1, as a major component of caveolae, is involved in the regulation of cell cycle by impacting various signaling pathways. Previous studies of caveolin-1 in cancer showed two contrary results. In most in vitro studies, caveolin-1 played a role as a tumor suppressor. On the other hand, the elevated expression of caveolin-1 was often(More)
BACKGROUND Assessment of Helicobacter pylori (H. pylori) clarithromycin resistance has rarely been performed routinely despite an increasing resistance rate. Our aim was to develop and evaluate the use of dual-priming oligonucleotide (DPO)-based multiplex polymerase chain reaction (PCR) to detect point mutations in the 23S rRNA gene responsible for(More)
T-DNA-tagged rice plants were screened under cold- or salt-stress conditions to determine the genes involved in the molecular mechanism for their abiotic-stress response. Line 0-165-65 was identified as a salt-responsive line. The gene responsible for this GUS-positive phenotype was revealed by inverse PCR as OsGSK1 (O ryza s ativa g lycogen s ynthase k(More)
Pleomorphic xanthoastrocytoma (PXA) is a rare primary brain tumor, which usually involves the superficial cortex in children and young adults. Although PXA is considered an astrocytic tumor, recent studies suggest the presence of neuronal differentiation and an origin from multipotential precursor cells. To clarify the clinicopathological characteristics,(More)
Mutations affecting spliceosomal proteins are the most common mutations in patients with myelodysplastic syndromes (MDS), but their role in MDS pathogenesis has not been delineated. Here we report that mutations affecting the splicing factor SRSF2 directly impair hematopoietic differentiation in vivo, which is not due to SRSF2 loss of function. By contrast,(More)
Ablation of a single miRNA gene rarely leads to a discernable developmental phenotype in mice, in some cases because of compensatory effects by other functionally related miRNAs. Here, we report that simultaneous inactivation of two functionally related miRNA clusters (miR-34b/c and miR-449) encoding five miRNAs (miR-34b, miR-34c, miR-449a, miR-449b, and(More)
Hypertension is one of the very serious diseases and, recently, hypertensive patient longevity has been increased significantly. Therefore, the development of new antihypertensive drugs or bioactive compounds is very important to remedy or prevent hypertension. The antihypertensive angiotensin I-converting enzyme (ACE) inhibitor in water extracts from the(More)
Bifidobacterium longum strains predominate in the colonic microbiota of breast-fed infants. Here we report the complete genome sequence of B. longum subsp. longum KACC 91563, isolated from feces of neonates. A single circular chromosome of 2,385,301 bp contains 1,980 protein-coding genes, 56 tRNA genes, and 3 rRNA operons.
