A beta-adrenoceptor agonist, norepinephrine (NE)-induced relaxation in the presence of an alpha-adrenoceptor antagonist and indomethacin was investigated in isolated femoral arteries from 5-week-old Wistar Kyoto rats (WKY) and spontaneously hypertensive rats (SHR). NE elicited endothelium-dependent and -independent relaxation in WKY. In endothelium-intact(More)
Bombesin (BN) and structurally related peptides, gastrin-releasing peptide (GRP) and neuromedin B (NMB), injected into the lateral ventricle produce multiple effects such as hypothermia, anorexia and hormone release. In this study, the pharmacological characteristics of BN receptors mediating hypothermia in the central nervous system (CNS) were investigated(More)
Secretory leukocyte protease inhibitor (SLPI) is a potent inhibitor of human leukocyte elastase. SLPI transcripts in the cervical tissue were detected during the menstrual cycle by reverse transcription-polymerase chain reaction (RT-PCR). Western blot analysis revealed that the intensity of SLPI protein in cervical tissue in the ovulatory phase was stronger(More)
Oncostatin M (OSM) is a member of the interleukin-6 superfamily and a multifunctional cytokine that effects the growth and differentiation of many different cell types. OSM concentrations in the sera of pregnant women were found to be significantly higher than those of non-pregnant women. Western blot analysis revealed that the OSM protein was present in(More)
The marine dinoflagellate Oxyrrhis marina has three major microtubular systems: the flagellar apparatus made of one transverse and one longitudinal flagella and their appendages, cortical microtubules, and intranuclear microtubules. We investigated the dynamic changes of these microtubular systems during cell division by transmission and scanning electron(More)
The lipocortins are a family of structurally related proteins that have been shown to be implicated in multiple aspects of cell biology. Subsequent research has shown that lipocortin 1 (LC1) participates in the physiological and pathological functioning of the CNS and neuroendocrine system. In the present study, the effects of 12-O-tetradecanoylphorbol(More)
The lipocortins are a family of structurally related proteins, namely an annexin family, that exerts a variety of cellular functions through Ca2+-dependent binding to phospholipase A2 [EC 3.1. 1.4], including a crucial role in the central nervous system (CNS) such as antipyrogenic, thermoregulatory and neuroprotective agents in vivo. To elucidate the(More)
Neurofibroma tissue was investigated for the presence of glial growth modulators that would suppress the proliferation of glial cells. A novel endogenous polypeptide inhibitor of proliferation and DNA synthesis in glial cells, gliostatin, was purified from the extracts of neurofibroma by a procedure comprising dye and anion-exchange column chromatography,(More)
Click beetles (Coleoptera: Elateridae) represent one of the largest groups of beetle insects. Some click beetles in larval form, known as wireworms, are destructive agricultural pests. Morphological identification of click beetles is generally difficult and requires taxonomic expertise. This study reports on the DNA barcoding of Japanese click beetles to(More)
OBJECTIVE The purpose of this study was to examine how gliostatin/platelet-derived endothelial cell growth factor (GLS/PD-ECGF) is involved in the molecular mechanism of cartilage degradation in rheumatoid arthritis (RA) with special reference to the GLS-induced gene expression and protein synthesis of matrix metalloproteinase (MMP)-1 (collagenase-1) and(More)
