The Notch-signalling pathway is important in establishing metameric pattern during somitogenesis. In mice, the lack of either of two molecules involved in the Notch-signalling pathway, Mesp2 or presenilin-1 (Ps1), results in contrasting phenotypes: caudalized versus rostralized vertebra. Here we adopt a genetic approach to analyse the molecular mechanism(More)
Humans and owls localize sounds by detecting the arrival time disparity between the ears. Both species determine the interaural time difference by finding the delay necessary to match the leading signal with the lagging one. This method produces ambiguity with periodic signals, because the two signals can be matched by delaying either one or the other. As(More)
To address the question of whether gamma-aminobutyric acid (GABA) induces a change in the concentration of Ca2+ in neurons of the developing visual cortex, and if so, to elucidate a developmental profile of such a GABA-induced change, we measured intracellular Ca2+ signals using microscopic fluorometry in visual cortical slices loaded with rhod-2. The(More)
Dermatomes of rats from C1 to T1 (forelimb) and from T12 to S2 (hindlimb) were determined by electrical stimulation of spinal nerves following the intravenous administration of Evans blue. After stimulation of the ventral ramus of a spinal nerve, a blue spotted area presenting the maximal innervation area of the spinal nerve appeared in the skin. Maximal(More)
The suprachiasmatic nucleus (SCN) of mammals is considered to be a circadian oscillator and it also demonstrates circadian rhythmicity of its multiple unit activity. A number of neuropeptides have been found in the SCN. Vasoactive intestinal peptide (VIP)- and vasopressin-containing neurons comprise large populations of these cells and have a distinct(More)
The effects of 3-week treatment with a typical antipsychotic drug chlorpromazine and three atypical antipsychotic drugs (risperidone, olanzapine and perospirone) on the binding to dopamine D2 and serotonin 5-HT2A receptors were examined in the rat stratum and frontal cortex, respectively. Subchronic treatment with chlorpromazine (10 mg/kg) and perospirone(More)
BACKGROUND We previously conducted gene expression microarray analyses to identify novel indicators for colorectal cancer (CRC) metastasis and prognosis from which we identified PVT-1 as a candidate gene. PVT-1, which encodes a long noncoding RNA, mapped to chromosome 8q24 whose copy-number amplification is one of the most frequent events in a wide variety(More)
In vivo occupation of dopamine D1, D2 and serotonin (5-HT)2A receptors by a novel antipsychotic drug, SM-9018 (perospirone hydrochloride; cis-N- [4- [4- (1,2-benzisothiazol-3-yl)- 1-piperazinyl]butyl]cyclohexane-1,2-dicarboximide monohydrochloride) and its major metabolite (ID-15036; N-[4-[4-(1,2-benzisothiazol-3-yl)-1-piperazinyl]butyl]-1-hydroxy-1 ,(More)
A 50-base synthetic oligodeoxynucleotide complementary to a portion of mouse nerve growth factor (NGF) mRNA was used as a probe for analysis of the expression of NGF gene. Northern blot analysis showed the presence of a major 1.3 kb transcript, which was identical in size to mouse NGF mRNA, in both C6Bu1 cells and rat astrocytes cultured from newborn rat(More)
