Contribution of the inositol 1,4,5-trisphosphate transduction cascade to the detection of "bitter" compounds in blowflies
Qin Ouyang; Hiroyasu Sato; Yoshihiro Murata; Atsushi Nakamura; Mamiko Ozaki; Tadashi Nakamura
COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY A-MOLECULAR & INTEGRATIVE PHYSIOLOGY, ELSEVIER SCIENCE INC, 153, 3, 309-316, Jul. 2009, Peer-reviwed, Bitter taste detection is very important for many species including flies, because it prevents the ingestion of toxic food. Although it has been known that flies have specific bitter-sensitive taste cells in their contact chemosensilla, the mechanism by which those cells transduce the chemical signal into electrical activity has remained elusive. In this study, we first confirmed that type D4 and D5 tarsal chemosensilla of the blowfly Phormia regina responded well to bitter substances. Then, recording impulses from type D4 chemosensilla, we examined the possibility that a G-protein-coupled inositol 1,4,5-trisphosphate (IP(3))-dependent transduction cascade is of importance in the bitter-sensitive taste cells. We found that the response to bitter substances was depressed by specific inhibitors of G-protein, phospholipase C, or IP(3) receptor in the tarsal taste receptor cells. These results suggest that G-proteins mediate the IP(3) pathway in the transduction cascade in bitter-sensitive receptor cells. (C) 2009 Elsevier Inc. All rights reserved.

Odour of limonene affects feeding behaviour in the blowfly, Phormia regina

NEUROSCIENCE LETTERS, ELSEVIER IRELAND LTD, 446, 1, 36-39, Nov. 2008, Peer-reviwed, Experiences of odours at meals are thought to affect food preference in many animals. To study appetite modulation by odours, we established a new experimental system based on the modification of a previous method, where flies fed sucrose flavoured with D-limonene subsequently showed reduced appetite to plain sucrose. In this new experimental system, a fly population was divided into two groups: (1) the "simultaneous" group of flies was exposed to D-limonene and sucrose simultaneously for 10 min, and (2) the "separate" group of flies was exposed to sucrose alone for 10 min, and 1 h later, to limonene for 10 min. The appetite of flies in the "separate" group for sucrose was unaffected by the experiment, but the appetite of flies in the "simultaneous" group was significantly decreased, and this effect lasted for >= 3 days. To investigate if this appetite modulation by D-limonene was based on long-term memory formation (protein synthesis), we examined the effects of the protein synthesis inhibitor, cycloheximide. Injection of cycloheximide 1 h after exposure to limonene and sucrose inhibited the appetite suppression in the "simultaneous" group of flies. In addition, to exclude the possibility that D-limonene exerted its effect through taste, rather than odour, we examined the effect of removing of the olfactory organs, antennae and maxillary palps on appetite modulation by D-limonene. When the olfactory organs were removed, no reduction in appetite was observed in the flies in the "simultaneous" group, indicating olfaction. In our new and effective appetite-modulation system for flies, modulation of appetite by olfactory detection of D-limonene was shown. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

Two isoforms of chicken melanopsins show blue light sensitivity
Masaki Torii; Daisuke Kojima; Toshiyuki Okano; Atsushi Nakamura; Akihisa Terakita; Yoshinori Shichida; Akimori Wada; Yoshitaka Fukada
FEBS LETTERS, WILEY, 581, 27, 5327-5331, Nov. 2007, Peer-reviwed, Melanopsin is a vertebrate non-visual opsin and functions as a circadian photoreceptor in mammalian retinas. Here we found the expression of two kinds of melanopsin genes in the chicken pineal gland and identified the presence of five isoforms derived from these two genes. Reconstitution of the recombinant proteins with 11-cis-retinal revealed that at least two of these melanopsin protein isoforms can function as blue-sensitive photopigments with absorption maxima at 476-484 nm. These values are consistent with maximal sensitivities of action spectra determined from the physiological and behavioral studies on mammalian melanopsins. The melanopsin isoforms found in this study may function as pineal circadian photoreceptors. (C) 2007 Federation of European Biochemical Societies. Published by Elsevier B. V. All rights reserved.

Regulatory mechanism for the stability of the meta II intermediate of pinopsin
A Nakamura; D Kojima; T Okano; H Imai; A Terakita; Y Shichida; Y Fukada
JOURNAL OF BIOCHEMISTRY, JAPANESE BIOCHEMICAL SOC, 129, 2, 329-334, Feb. 2001, Peer-reviwed, Pinopsin is a chicken pineal photoreceptive molecule with a possible role in photoentrainment of the circadian clock. Sequence comparison among members of the rhodopsin family has suggested that pinopsin might have properties more similar to cone visual pigments than to rhodopsin, but the lifetime of the physiologically active intermediate (meta II) of pinopsin is rather similar to that of metarhodopsin II, which is far more stable than meta II intermediates of cone visual pigments [Nakamura, A. et al., (1999) Biochemistry 38, 14738-14745]. In the present study, we investigated the amino acid residue(s) contributing to this unique property of pinopsin by using site-directed mutagenesis to pinopsin-specific structural features, (i) Ser171, (ii) Asn184, and (iii) the second extracellular loop two-amino acids shorter than that of cone visual pigments. The meta II stability of the 171/184 double mutant of pinopsin (S171R/N184D) is almost the same as that of wild-type pinopsin. In contrast, the meta II lifetime is markedly shortened (one third) by introduction of the third mutation (replacement of a six-amino acid stretch, 188-193, by the corresponding eight residues of chicken green-sensitive cone pigment) to the 171/184 double mutant of pinopsin. Consistently, meta II of the green-sensitive pigment mutant, in which the eight-amino acid stretch is inversely replaced by the corresponding six residues of pinopsin, is more stable than meta II of the wild-type pigment. These results strongly suggest that the specific sequence and/or the number of residues at amino acids 188-193 in pinopsin play an important role in the stabilization of the meta II intermediate.

Chimeric nature of pinopsin between rod and cone visual pigments
A Nakamura; D Kojima; H Imai; A Terakita; T Okano; Y Shichida; Y Fukada
BIOCHEMISTRY, AMER CHEMICAL SOC, 38, 45, 14738-14745, Nov. 1999, Peer-reviwed, Chicken pineal pinopsin is the first example of extra-retinal opsins, but little is known about its molecular properties as compared with retinal rod and cone opsins. For characterization of extraretinal photon signaling, we have developed an overexpression system providing a sufficient amount of purified pinopsin. The recombinant pinopsin, together with similarly prepared chicken rhodopsin and green-sensitive cone pigment, was subjected to photochemical and biochemical analyses by using low-temperature spectroscopy and the transducin activation assay. At liquid nitrogen temperature (-196 degrees C), we detected two kinds of photoproducts, bathopinopsin and isopinopsin, having their absorption maxima (lambda(max)) at 527 and similar to 440 nm, respectively, and we observed complete photoreversibility among pinopsin, bathopinopsin, and isopinopsin. A close parallel of the photoreversibility to the rhodopsin system strongly suggests that light absorbed by pinopsin triggers the initial event of cis-trans isomerization of the 11-cis-retinylidene chromophore. Upon warming, bathopinopsin decayed through a series of photobleaching intermediates: lumipinopsin (lambda(max) 461 nm), metapinopsin I (460 nm), metapinopsin II (385 nm), and metapinopsin III (460 nm). Biochemical and kinetic analyses showed that metapinopsin II is a physiologically important photoproduct activating transducin. Detailed kinetic analyses revealed that the formation of metapinopsin IT is as fast as that of a chicken cone pigment, green, but that the decay process of metapinopsin II is as slow as that of the rod pigment, rhodopsin. These results indicate that pinopsin is a new type of pigment with a chimeric nature between rod and cone visual pigments in terms of the thermal behaviors of the meta II intermediate. Such a long-lived active state of pinopsin may play a role in the pineal-specific phototransduction process.

Immunocytochemical identification of pinopsin in pineal glands of chicken and pigeon
T Okano; Y Takanaka; A Nakamura; K Hirunagi; A Adachi; S Ebihara; Y Fukada
MOLECULAR BRAIN RESEARCH, ELSEVIER SCIENCE BV, 50, 1-2, 190-196, Oct. 1997, Peer-reviwed, Pinopsin is a blue-sensitive photoreceptive molecule possibly involved in photic entrainment of the circadian pacemaker in the chicken pineal gland. To characterize pinopsin as a circadian photoreceptor, antibodies were raised against the C-terminal portion of pinopsin. Its expected from the divergence of the amino acid sequence of this region, the resultant antibody cross-reacted with neither chicken rhodopsin nor red-sensitive cone pigment (chicken red). in Western blot analysis, the antibody stained a single band of 42-kDa protein in a detergent-extract of chicken pineal membranes, suggesting that pinopsin (calculated molecular weight, 38 187) might be glycosylated and/or palmitoylated. Immunocytochemical examination of pineal sections of the chicken and the pigeon with this antibody revealed strong positive images for most of the membrane structures in the lumen of the follicles. This antibody also stained string- and bulb-shaped structures of the chicken parafollicular cells, the morphology of which resembles those of retinal photoreceptor cells. In contrast to the predominant distribution of pinopsin, a monoclonal antibody specific for chicken red stained a smaller number of membrane structures in the lumen of chicken pineal follicles. These results strongly suggest that the chicken pined gland contains at least two types of photoreceptive molecules, pinopsin (major) and chicken red (minor). We show that the former molecule is localized in parafollicular pinealocytes and in the outer segments of pinealocytes that make contact with the follicular lumen. (C) 1997 Elsevier Science B.V.

Analyses of physiological role of circadian clock in the ovary
NAKAMURA Tomoko; NAKAMURA Atsushi
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Hokkaido University, Grant-in-Aid for Scientific Research (C), Current understanding in the field is that the circadian clock in the suprachiasmatic nucleus controls the phase of circadian clock in the peripheral organs. However, the mechanism of the control is remained to be shown. In this study, we used the rat ovary as a model of the peripheral organ, and investigated the potency of LH to control the phase of the circadian clock. When LH level was kept at a constant level in the rat by a pharmacological or surgical method, the amplitude of circadian oscillation was significantly decreased. The result indicates that LH is important to maintain circadian oscillation in the ovary., 19599001
