Despite the fact that glycine-rich RNA-binding proteins (GRPs) have been implicated in the responses of plants to environmental stresses, their physiological functions and mechanisms of action in stress responses remain largely unknown. Here, we assessed the functional roles of GRP7, one of the eight GRP family members in Arabidopsis thaliana, on seed(More)
DEAD-box RNA helicases have been implicated to have a function during stress adaptation processes, but their functional roles in plant stress responses remain to be clearly elucidated. Here, we assessed the expression patterns and functional roles of two RNA helicases, AtRH9 and AtRH25, in Arabidopsis thaliana under abiotic stress conditions. The transcript(More)
Caffeic acid phenethyl ester (CAPE), an the active component of propolis, is known to have anticarcinogenic, antiviral and various biological activities; however, the effect of CAPE on the immunomodulatory activity in vivo remains unknown. We have investigated the effect of CAPE on the immune system in female Balb/c mice. CAPE (0, 5, 10, 20 mg/kg) was given(More)
BACKGROUND Ursolic acid, a pentacyclic triterpenoid, is known to exert antitumor activity in breast, lung, liver and colon cancers. Nonetheless, the underlying mechanism of ursolic acid in prostate cancer cells still remains unclear. To investigate the antitumor mechanism, the apoptotic mechanism of ursolic acid via Wnt/β-catenin signaling was examined in(More)
Stimulation of murine macrophages with corn silk induced cyclooxygenase (COX)-2 with secretion of PGE2. Expression of COX-2 was inhibited by pyrolidine dithiocarbamate (PDTC), and increased DNA binding by nuclear factor kappa B (NF-kappaB), indicating that COX-2 induction proceeds also via the NF-kappaB signaling pathway. A specific inhibitor of COX-2(More)
[Purpose] In the present study, we aimed to determine the effects of backpack position on foot weight distribution of standing school-aged children. [Subjects] Thirty school-aged children volunteered to participate in this study. [Methods] The subjects randomly performed four types of carrying a backpack: no backpack (condition-1), carrying a backpack at C7(More)
Corn silk has been purified as an anticoagulant previously and the active component is a polysaccharide with a molecular mass of 135 kDa. It activates murine macrophages to induce nitric oxide synthase (NOS) and generate substantial amounts of NO in time and dose-dependent manners. It was detectable first at 15 h after stimulation by corn silk, peaked at 24(More)
Gap junctions that allow for a direct exchange of second messenger and ions are the most conserved cellular structures in multicellular organisms. We have isolated and characterized a Bombyx mori gene innexin3 that encodes a new member of the innexin family required for the early embryonic development. The BmINX3 mRNA was 1,814 nucleotide residues in(More)
The femtosecond laser-induced grating (FLIG) formation and crystallization were investigated in amorphous silicon (a-Si) films, prepared on glass by plasma-enhanced chemical-vapor deposition. Probe-beam diffraction, micro-Raman spectroscopy, atomic force microscopy, scanning electron microscopy, and transmission electron microscopy were employed to(More)
