The distribution of nitric oxide synthase (NOS) in the mouse olfactory bulb and olfactory epithelium, including the vomeronasal organ, was studied using an anti-NOS antibody, NADPH diaphorase histochemistry and in situ hybridization with NOS specific antisense oligonucleotide probes. Interneurons containing NOS protein and mRNA, and exhibiting NADPH(More)
The precise cellular localization of mRNAs for putative odorant receptors was investigated in the mouse chemosensory system (olfactory epithelium, septal organ and vomeronasal organ). Four additional members of the odorant receptor family were cloned from mouse olfactory mucosa and in situ hybridization was performed with paraffin-embedded tissue using(More)
The purpose of this study was to determine whether immobilization stress can cause changes in the enzyme activity and gene expression of neuronal nitric oxide synthase (nNOS) in the hypothalamus, pituitary, and adrenal gland in rats. NOS enzyme activity was measured as the rate of [3H]arginine conversion to citrulline, and the level of nNOS mRNA signal was(More)
Three mouse olfactory receptors have been cloned and sequenced and were found to be expressed in different zones of the olfactory epithelium. In situ hybridisation (ISH) results showed that each olfactory receptor was expressed at an early stage in development (E12), was not dependent on the maturation of the receptor neurons, and was present long before(More)
Changes of three different cytosolic Ca2+ binding proteins, calbindin-D28k, calretinin, and parvalbumin mRNA expression in the brain of the hamster during aging were investigated by in situ hybridization using brains from hamsters aged 4, 9, 13, 19, to 24 months old. In cerebellum area, calbindin-D28k transcripts showed about 50% to 68% decrease in content(More)
Calretinin immunoreactivity was demonstrated in adult mouse olfactory receptor neurons and in the vomeronasal and septal chemoreceptor neurons, whereas parvalbumin expression was restricted to the vomeronasal receptor neurons. Calbindin-D28k-like immunoreactivity was primarily localized in the vomeronasal and septal chemoreceptor neurons although an(More)
Four mouse vomeronasal receptors (mV1Rs) have been isolated by similarity to rat vomeronasal receptor (V1R) motifs. The four mV1Rs identified in this study are members of two distinct subfamilies. Specific in situ hybridization probes (ISH) derived from the 3' non-coding regions of the mV1R genes, were used to detect expression of a single receptor and(More)
D-serine is an endogenous coagonist of the N-methyl-D-aspartate (NMDA)-type glutamate receptor in the central nervous system and its synthesis is catalyzed by serine racemase (SR). Recently, the NMDA receptor has been found to be expressed in keratinocytes (KCs) of the skin and involved in the regulation of KC growth and differentiation. However, the(More)
Transforming growth factor-beta-activated kinase 1 (TAK1) is a member of the NF-kappaB pathway and regulates inflammatory responses. We previously showed that TAK1 also regulates keratinocyte growth, differentiation, and apoptosis. However, it is unknown whether TAK1 has any role in epithelial-mesenchymal interactions. To examine this possibility, we(More)
