We have identified a novel octamer binding factor (Oct-3) in P19 embryonal carcinoma cells. Oct-3, which recognizes the typical octamer motif (ATTTGCAT) as well as the AT-rich sequence TTAAAATTCA, is present in P19 stem cells but disappears when the cells are induced to differentiate by retinoic acid (RA). Cloned cDNA corresponding to Oct-3 encodes a(More)
Our present knowledge on chemically modified proteins and their receptor systems is originated from a proposal by Goldstein and Brown in 1979 for the receptor for acetylated LDL which is involved in foam cell formation, one of critical steps in atherogenesis. Subsequent extensive studies using oxidized LDL (OxLDL) as a representative ligand disclosed at(More)
The scavenging effects of tea catechins and their epimerized, acylated, and glucostylated derivatives on 1,1-diphenyl-2-picrythydrazyl (DPPH) radical were evaluated by electron spin resonance spectrometry. Tea catechins and their epimers were shown to have 50% radical scavenging ability in the concentration range of 1 to 3 microM. No significant differences(More)
Human pregnancy represents a situation of semiallograft to maternal host. Therefore, it has been reported that tolerance to the fetal allograft represents a mechanism for maintaining a pregnancy. CD4(+)CD25(bright) regulatory T cells are known to play an important role in the development and maintenance of tolerance in peripheral tissues. However, the(More)
The molecular mechanisms underlying the development of the external genitalia in mammals have been very little examined. Recent gene knockout studies have suggested that the developmental processes of its anlage, the genital tubercle (GT), have much in common with those of limb buds. The Fgf genes have been postulated as regulating several downstream genes(More)
We have used a rat glutathione S-transferase P (GST-P) complementary DNA as a probe to screen a human placenta complementary DNA library constructed in the lambda gt11 vector. One of the positive clones contained the complete coding region (630 base pair) and the entire 3'-noncoding region (78 base pair) of the putative human glutathione S-transferase pi(More)
The activation of rainbow trout (Oncorhyndus mykiss) phagocytic cells by chum salmon GH, prolactin (PRL) and somatolactin (SL) was investigated in vitro. Rainbow trout kidney leucocytes were cultured in RPMI 1640 medium containing 1, 10, 50 or 100 ng of each hormone/ml and the production of superoxide anion was measured using reduction of nitroblue(More)
Chum salmon, Oncorhynchus keta, growth hormone and prolactin induced a direct proliferative response on chum salmon peripheral blood leukocytes in vitro. Maximal responses were obtained using 10-100 ng ml-1 of both hormones and were equivalent to the proliferation reference obtained with 100 micrograms concanvalin A ml-1.
Neuregulin-1 (NRG1) gene is implicated in the etiology or neuropathology of schizophrenia, although its biological contribution to this illness is not fully understood. We have established an enzyme-linked immunosorbent assay (ELISA), which recognizes the NRG1beta1 immunoglobulin-like (Ig) domain, and measured soluble Ig-NRG1 immunoreactivity in the sera of(More)
1. Intrathecal (i.t.) administration of nociceptin and high doses of morphine induced allodynia in response to innocuous tactile stimuli, and i.t. nociceptin evoked hyperalgesia in response to noxious thermal stimuli in conscious mice. Here we have characterized the nociceptin-induced allodynia and compared it with the morphine-induced allodynia and the(More)
