English, Scientific journal, Viviparous Sebastes rockfish males place their urogenital papilla close to the females' snout during courtship behavior, possibly to expose females to certain urinary substances. The urine of rockfish males contains abundant protein constituents that putatively act in inter-sexual chemical signaling. Here, we characterized low-molecular-weight urinary proteins (LMWups) from black rockfish (S. schlegelii). The LMWups were semi-purified from the urine of a male by cation-exchange chromatography for N-terminal sequencing, yielding a sequence of 35 amino acids (AAs) with only five unidentified residues. The black rockfish genome harbored three regions whose deduced AAs matched the obtained N-terminal sequence. Mapping of public RNA-seq reads enabled us to infer gene structures underlying these genomic regions. The proteins coded by these regions showed characteristics of members of the three-finger protein (TFP) family, which includes snake three-finger toxins and amphibian pheromones. We termed them as "sebastexins". Further in silico searches identified seven additional potential sebastexin gene loci in the black rockfish genome. Transcriptome analysis using a public dataset suggested that the kidney and liver are the major tissues expressing the sebastexin transcripts. The presence of sebastexin transcripts and proteins in the kidney and urine of males were empirically verified by cDNA cloning, Western blotting, and mass spectrometry. Histological analysis showed that a major sebastexin isoform is, at least in part, produced in the epithelial cells of the renal tubules of the male kidney. Collectively, these findings identify and partly characterize sebastexin TFP family proteins in rockfish urine. The potential biological function of these sebastexins is discussed. - Androgens induce renal synthesis of urinary lipocalin-family protein, a potential inter-sexual transmitter in viviparous rockfish

English, Scientific journal, Seasonal changes are more robust and dynamic at higher latitudes than at lower latitudes, and animals sense seasonal changes in the environment and alter their physiology and behavior to better adapt to harsh winter conditions. However, the genetic basis for sensing seasonal changes, including the photoperiod and temperature, remains unclear. Medaka (Oryzias latipes species complex), widely distributed from subtropical to cool-temperate regions throughout the Japanese archipelago, provides an excellent model to tackle this subject. In this study, we examined the critical photoperiods and critical temperatures required for seasonal gonadal development in female medaka from local populations at various latitudes. Intraspecific differences in critical photoperiods and temperatures were detected, demonstrating that these differences were genetically controlled. Most medaka populations could perceive the difference between photoperiods for at least 1 h. Populations in the Northern Japanese group required 14 h of light in a 24 h photoperiod to develop their ovaries, whereas ovaries from the Southern Japanese group developed under 13 h of light. Additionally, Miyazaki and Ginoza populations from lower latitudes were able to spawn under short-day conditions of 11 and 10 h of light, respectively. Investigation of the critical temperature demonstrated that the Higashidori population, the population from the northernmost region of medaka habitats, had a critical temperature of over 18 °C, which was the highest critical temperature among the populations examined. The Miyazaki and the Ginoza populations, in contrast, were found to have critical temperatures under 14 °C. When we conducted a transplant experiment in a high-latitudinal environment using medaka populations with different seasonal responses, the population from higher latitudes, which had a longer critical photoperiod and a higher critical temperature, showed a slower reproductive onset but quickly reached a peak of ovarian size. The current findings show that low latitudinal populations are less responsive to photoperiodic and temperature changes, implying that variations in this responsiveness can alter seasonal timing of reproduction and change fitness to natural environments with varying harshnesses of seasonal changes. Local medaka populations will contribute to elucidating the genetic basis of seasonal time perception and adaptation to environmental changes. - Identification and characterization of lipocalin-type prostaglandin D2 synthase homologs in the urine of male rockfish

English, Scientific journal, Fundamental knowledge on the regulation of reproduction by gonadotropins (Gths) is quite limited in viviparous fishes. In the present study, we performed molecular cloning and characterization of cDNAs encoding two Gth subunits (fshb and lhb) from the pituitaries of viviparous white-edged rockfish, Sebastes taczanowskii; expression profiles of both gene transcripts were elucidated in the pituitaries of reproductive males and females which were kept in a captive environment. The cloned fshb and lhb fragments exhibited high sequence identities with corresponding β-subunit sequences from black rockfish, S. schlegelii. Notably, the fshb of white-edged rockfish appeared to lack a putative N-glycosylation site, whereas lhb conserved it. Expression of fshb and lhb transcripts in the rockfish pituitaries largely changed in synchrony but for minor exceptions. In males, levels of both transcripts increased with progression of spermatogenesis, although the peak for fshb (October) appeared slightly earlier than that for lhb (November). In females, both gene transcripts exhibited synchronous bimodal changes. High expression of fshb and lhb transcripts in the female pituitary during the gestation period, followed by the drastic decrease at parturition, suggest their possible involvement in regulation of gestation of this species. The knowledge gained for Sebastes in this study superimposes fundamental information necessary for further physiological understanding of viviparity in teleost fish. - Hepatic estrogen-responsive genes relating to oogenesis in cutthroat trout (Oncorhynchus clarki): The transcriptional induction in primary cultured hepatocytes and the in vitro promoter transactivation in responses to estradiol-17β.

English, Scientific journal, Estradiol-17β (E2) regulates transcription of estrogen-responsive genes via estrogen receptors (Esr). In many teleost species, choriogenin (chg), vitellogenin (vtg) and esr genes are transactivated by E2 in the liver. This study aimed i) to compare expression properties of all subtypes of these genes (chg: chgHα, chgHβ, chgL; vtg: vtgAs, vtgC; esr: esr1a, esr1b, esr2a, esr2b) in response to estrogen stimulation, and ii) to confirm how each of four Esr subtypes is involved in the transcriptional regulation of these estrogen-responsive genes in cutthroat trout hepatocytes. In hepatocytes in primary culture, all chg and vtg subtype mRNA levels, and those of esr1a, were increased by E2 treatment (10-6 M) at 24 and 72 h post initiation (hpi), but esr1b, esr2a and esr2b mRNA levels were not. Treatment of hepatocytes with various concentrations of E2 (10-11-10-6 M) induced dose-dependent increases in the levels of all chg and vtg subtype mRNAs at 24 and 72 hpi. At both time points, the lowest dose that induced a significant increase in the expression levels of mRNAs (LOEC) for E2 differed among the genes; LOECs were estimated as 10-11 M for chgHα at 24 hpi, as 10-9 M for vtgC at 72 hpi, and as 10-10 M for other mRNAs at both 24 and 72 hpi. Meanwhile, the levels of esr1a mRNA exhibited a dose-dependent increase at 24 and 72 hpi, but the LOEC shifted from 10-9 M at 24 hpi to 10-7 M at 72 hpi because of a decrease in mRNA levels at treatment groups exposed to high concentrations of E2. All Esr subtypes transactivated chg, vtg and esr1a promoters in the presence of E2 in vitro. The activation levels indicated that promoter activity of chgHα ≥ vtgAs > chgHβ > chgL ≥ vtgC ≥ esr1a when mediated by Esr1a, chgHβ > chgHα > chgHL > vtgAs ≥ vtgC ≥ esr1a by Esr1b, chgHβ ≥ chgL > chgHα ≥ vtgAs > vtgC > esr1a by Esr2a, and chgHβ ≥ chgHα ≥ vtgAs > chgL ≥ vtgC > esr1a by Esr2b. Collectively, different Esr subtypes were distinctly different in their ability to transactivate estrogen-responsive target genes, resulting in differential expression of chg, vtg and esr1a genes in the estrogen-exposed hepatocytes. - Changes in the Hepatic Expression of Three Vitellogenin Subtype Genes During Ovarian Development in Female White-Edged Rockfish (Sebastes taczanowskii)

English, Scientific journal, Recent studies of vitellogenesis engendered a novel model of teleost yolk formation in which multiple yolk precursors, vitellogenins (Vtgs), and their receptors (Vtgrs) interact to ensure proper yolk composition for embryonic development and larval growth. As a step toward verification of this concept, we examined the role of one candidate Vtgr, termed low-density lipoprotein receptor relative with eight ligand-binding repeat (Lr8), in the medaka, a representative teleost and established laboratory model. A homozygous lr8 knock out (lr8-KO) medaka was produced to perform reverse-genetic functional analyses. In ovaries of wild type (WT) medaka, Western blotting detected a putative Lr8 protein band at ~130 kDa, while immunohistochemistry detected the putative Lr8 signal at the periphery of the oocyte underneath the zona radiata. These signals disappeared in ovaries of the lr8-KO group. Offspring of lr8-KO medaka exhibited decreased survival rate compared to WT fish, but KO of lr8 was not 100% lethal. There was no significant difference in total yolk protein content or size of eggs between WT and lr8-KO fish. However, LC-MS/MS analyses revealed a remarkable decrease in the relative abundance of yolk proteins derived from VtgAb in lr8-KO eggs, in conjunction with a compensatory increase in proteins derived from VtgAa1. These findings strongly support the conclusion that Lr8 is an important receptor for VtgAb in medaka. The disruption of proper yolk composition by lr8-KO is possibly one cause of the low offspring survival. - Development and characterization of polyclonal antibodies against subtype specific vitellogenin of the dojo loach, Misgurnus anguillicaudatus

English, Scientific journal, Egg quality in fishes has been a topic of research in aquaculture and fisheries for decades as it represents an important life history trait and is critical for captive propagation and successful recruitment. A major factor influencing egg quality is proper yolk formation, as most fishes are oviparous and the developing offspring are entirely dependent on stored egg yolk for nutritional sustenance. These maternally derived nutrients consist of proteins, carbohydrates, lipids, vitamins, minerals, and ions that are transported from the liver to the ovary by lipoprotein particles including vitellogenins. The yolk composition may be influenced by broodstock diet, husbandry, and other intrinsic and extrinsic conditions. In addition, a number of other maternal factors that may influence egg quality also are stored in eggs, such as gene transcripts, that direct early embryonic development. Dysfunctional regulation of gene or protein expression may lead to poor quality eggs and failure to thrive within hours of fertilization. These gene transcripts may provide important markers as their expression levels may be used to screen broodstock for potential spawning success. In addition to such intrinsic factors, stress may lead to ovarian atresia or reproductive failure and can impact fish behavior, fecundity, and ovulation rate. Finally, postovulatory aging may occur when eggs become overripe and the fish fails to spawn in a timely fashion, leading to low fertility, often encountered during manual strip spawning of fish. - Molecular cloning of vitellogenin gene promoters and in vitro and in vivo transcription profiles following estradiol-17 beta administration in the cutthroat trout

Japanese, Whole-mount immunostaining (WI) was used for identification of eggs of brown sole (Pseudopleuronectes herzensteini), sand flounder (Limanda punctatissima) and pointhead flounder (Cleisthenes pinetorum). Polyclonal antibodies were raised in rabbit against vitelline envelope (VE) of ovulated eggs of each flounder (a-brown sole VE, a-sand flounder VE and a-pointhead flounder VE). A WI method was first developed using the non-labeled primary a-VE antibodies in conjunction with a labeled-secondary antibody (2-step method). Another WI method using the labeled-primary a-VE anitbodies alone was developed (1-step method) in order to omit the use of the secondary antibody. When fertilized eggs of each species (2-24 hrs post-fertilization) were examined, both WI methods effectively stained the eggs in a species-specific manner. Immunological tools developed for identification of flounder eggs in this study will contribute to simplify fishery surveys of flounder species during their early life stages. - Expression analysis of estradiol-17β responsive genes in the liver of female cutthroat trout (Oncorhynchus clarki) during a reproductive cycle

Japanese, Choriogenin (Chg) and vitellogenin (Vtg) subtypes and estrogen receptor α1 (Erα1) are upregulated by estradiol-17β (E2) in the liver of female salmonids. The aim of this study was to examine the relationships among hepatic mRNA levels for chgs (chgHα; chgHβ; chgL), vtgs (vtgAs; vtgC), erα1 and serum E2 levels in female cutthroat trout (Oncorhynchus clarki) during a reproductive cycle. Levels of serum E2 and hepatic chg mRNAs, as well as hepatic vtg mRNAs, increased in correlation with the progress of vitellogenesis. In the ovulated fish, chg mRNA remained at high levels while serum E2 and vtg mRNA levels decreased. Hepatic erα1 mRNA levels exhibited a peak in August (at the beginning of vitellogenesis) before levels of E2, chg and vtg mRNAs start to increase. These results suggest that expression levels of chg, vtg and erα1 genes are potentially regulated through E2 stimulation by different mechanisms. - Ovarian expression and localization of clathrin (Cltc) components in cutthroat trout, Oncorhynchus clarki: Evidence for Cltc involvement in endocytosis of vitellogenin during oocyte growth

English, Black rockfish (Sebastes schlegelii) is an economically important aquaculture species in Japan. Because it is a viviparous species, seedling production is typically performed using natural mating and the numbers of larva that are produced tend to be unstable. In the present study, we aimed to develop artificial insemination techniques for black rockfish to ensure stable seedling production. We used 20 female and 15 male mature individuals and examined when artificial insemination is best performed, in which diluent the sperm is best diluted and whether sperm collected from live or dead males both have fertilizing capability. The number of larvae produced by each pregnant female was counted. In addition, microsatellite markers were used to determine the relationship between larvae and parents. Following artificial insemination, 12 of 20 females became pregnant. The average litter size per pregnant female was about 130,000 fry. Pregnant females were obtained under all experimental conditions, regardless of season, sperm diluent and whether the male was live or dead. Paternity testing revealed that all larvae were produced by artificial insemination. Furthermore, females artificially inseminated by several males appeared to produce offspring derived from all males. The present study demonstrates that artificial insemination is possible in marine viviparous fish. - Molecular cloning and characterization of hagfish estrogen receptors

English, Molecular cloning of cDNAs encoding an egg yolk precursor, vitellogenin (Vtg), was performed using the liver of estrogen-treated Amur sturgeon. Three kinds of vtg cDNA were cloned and temporarily named as vtg1, vtg2 and vtg3. These vtg cDNAs were obtained as contiguous sequences; each of vtg1, vtg2 and vtg3 sequences contained a complete open reading frame (5,307, 5,247 and 5,319 bp, respectively), each encoding 1,769, 1,749 and 1,773 aa residues, respectively. Similarity among amino acid sequences deduced from the three vtg cDNAs were relatively low, ranging from 64.3% to 47.9%. Three Vtgs appeared to be a complete-type, consisting of all representative yolk protein domains. Phylogenetic analysis revealed that Amur sturgeon Vtg1 formed a clade together with a published white sturgeon Vtg, while Amur sturgeon Vtg2 and Vtg3 formed another distinct clade. The results of phylogenetic analysis confirmed all three Vtgs belong to VtgAB type; vtg1/Vtg1, vtg2/Vtg2 and vtg3/Vtg3 were hereby designated as vtgAB1/VtgAB1, vtgAB2a/VtgAB2a and vtgAB2b/VtgAB2b, respectively. This study provided a basis to understand multiplicity in sturgeon vtg/Vtg and set a stage for their future application as reproductive biomarkers in sturgeon aquaculture. - Molecular Cloning and Partial Characterization of a Low-Density Lipoprotein Receptor-Related Protein 13 (Lrp13) Involved in Vitellogenin Uptake in the Cutthroat Trout (Oncorhynchus clarki)

English, Immunoglobulin M (IgM) was purified from the serum of Sakhalin taimen (Hucho perryi) by salting-out, ion-exchange chromatography on DEAF-cellulose, and gel filtration on Sepharose 6B. The intact, tetrameric taimen IgM has a mass of 750 kDa with molecular architecture typical of IgM from other salmonids. The molecular weights of heavy (μ) chain and light chains (L) of the IgM monomer were estimated to be 68 kDa and 23 kDa, respectively. Purified taimen IgM was used to raise a specific rabbit antiserum and to develop a single radial immunodiffusion assay for measuring circulating IgM levels. The serum IgM levels in captive, immature or maturing female taimen varied between 1 and 5 mg/ml, showing seasonal changes regardless of fish age, with relatively low levels in spring and conversely high levels in autumn. Production of specific serum IgM to a parasite, Salmincola stellatus, was assessed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotting. The parasitized taimen serum could react with protein components of aqueous extracts from the parasite that were blotted on a nitrocellulose membrane after SDS-PAGE, but normal taimen serum did not, indicating that the parasitized fish produced the specific IgM to S. stellatus in the serum. - Development and validation of chemiluminescent immunoassay for vitellogenin in five salmonid species

MORITA Yuka, HIRAMATSU Naoshi, IWASAKI Toshihide, TODO Takashi, HARA Akihiko, The Journal of Reproduction and Development Supplement, 104, 0, 1066, 1066, 2011
【目的】Pregnancy-associated glycoprotein (PAG)は胎盤で発現する妊娠関連タンパク質であり,妊娠母体の血中に出現することから,その検出や動態は数種の陸生哺乳類において妊娠の診断やモニタリング等に利用されている。本研究は鯨類における繁殖生理機構の一端を解明し,得られた知見を繁殖管理へ応用することを目的としてスジイルカPAG cDNAのクローニングを行った。【方法】 試料には和歌山県太地町のイルカ漁にて捕獲されたスジイルカを用いた。妊娠初期から後期のスジイルカ4個体から得た胎盤をプールしRNAを抽出後,cDNAを合成した。他の陸上哺乳類PAGの配列を元に設計したdegenerateプライマーと胎盤cDNAをPCRに供し,得られたPAG様PCR産物の配列を決定した。さらに5'および3'RACE法を用いてPAGのcDNAクローニングを行い,全一次構造の解析を試みた。【結果】スジイルカ胎盤組織より PAG のクローニングを行った結果,6 種類のPAG cDNA (pag1~6) が確認され,それらは397個(pag1,2)および404個(pag3~6)のアミノ酸翻訳領域から構成されていた。同アミノ酸配列は他の陸上哺乳類 pag と高い相同性を示し,本種の PAG をコードしていると考えられた。スジイルカpag配列には3~5個のN-glycosylationサイトおよびアスパラギン酸プロテアーゼファミリーに特徴的なドメインが含まれていた。またアスパラギン酸プロテアーゼ活性に必要なcatalytic モチーフを含んでいたことより,構造的には同活性を持ち得る可能性が示唆された。各pag cDNAの塩基配列および演繹アミノ酸配列は約90%以上の相同性を示したが,系統樹を作成したところ,2つのクラスターに分類された。さらに本種pag配列は同モチーフを有するウマおよびブタpag配列に最も近いクレードを形成した。以上本研究によりスジイルカのPAGが遺伝子レベルで同定され,鯨類で初めて詳細な性状が明らかとなった。, THE SOCIETY FOR REPRODUCTION AND DEVELOPMENT, Japanese - カットスロートトラウト(Oncorhynchus clarki)における2型ビテロジェニン遺伝子の発現解析

本研究では、魚類カロテノイド分解に関わる遺伝子候補に着目し、その翻訳制御機構を解明すると共に、同候補のゲノム編集が身色形質の改善に有効か否かを試すことを目的とする。目的達成に向け、「スカベンジャー受容体クラスBタイプ1(srb1)を介したアスタキサンチン(Ax)取込み量を増やし、βカロテンオキシゲナーゼ(bco)による分解を抑えることができれば、最終的に筋肉のAx蓄積量が増え赤色呈色性が強くなる」と仮説を立て、これを直接的にゲノム編集により実証する課題1と、未知な点が多いsrb1及びbcoの翻訳制御機構を明らかにする課題2を実施する。
R5年度は、公開ゲノムデータベースを探索し、ニジマスではbco1, bco1l, srb1遺伝子、メダカではbco1とbco1l遺伝子について、各ゲノム上の位置や配列を特定した。この情報を基に、課題1では、各遺伝子のガイドRNA(gRNA)を設計・合成した。これらのgRNAとCas9ヌクレアーゼを用いて、ニジマス及びメダカの受精卵に顕微注入し作出したF0胚について、ヘテロ二本鎖移動度分析(HMA)とシーケンス解析結果、両種ともにbco1lに関しては、変異導入個体が確認できた。一方で、その他の遺伝子については、変異導入個体の作出に至らなかった。課題2に関しては、両種から上記遺伝子転写産物のcDNAクローニングを行い、全てのクローニングを完了した。メダカbco1lについては、組換え蛋白質とその抗体を作製し、抗原組換え蛋白質との免疫陽性反応を得た。この抗体を用いて、消化管試料のウェスタンブロッティングを実施したが、陽性反応は確認できなかった。現在、bco1l以外の遺伝子由来の組換え蛋白質の作製も継続中である。一方、身色の赤色呈色を獲得前の若年魚と同呈色獲得後の出荷魚を用い、消化管におけるmiRNA発現データの取得を行った。

本研究は、魚類の卵母細胞における広義の卵黄物質、すなわち中性脂質(油球)と卵黄タンパク質(卵黄球)の蓄積機構について、それらに関わる重要な分子群の機能を最先端のゲノム編集技術を用いることにより解析し、明らかにすることを目的としている。メダカを研究モデルとし、「課題1:油球形成機構の解析」と「課題2:卵黄球形成機構の解析」の2課題を設定して研究を進めている。
課題1:先ず、油球を構成する中性脂質の主要な供給源である超低密度リポタンパク質の代謝酵素(リポタンパクリパーゼ:Lpl)に着目し、メダカ卵濾胞組織におけるlpl遺伝子の発現を解析した。その結果、2種類のlpl遺伝子(lpl1とlpl2)のうち、lpl1のみが発現していることが示されたことから、lpl1の遺伝子欠損(KO)メダカを作出することとした。CRISPR/Cas9システムによる効率的な変異導入を達成するため、lpl1遺伝子に対する複数のガイドRNA(gRNA)候補を設計して検討した結果、フレームシフトを伴う変異導入に有効なgRNAの組み合わせが見出された。
課題2:卵黄タンパク前駆物質(ビテロジェニン:Vtg)の卵内への取り込みに必要な3種のリポタンパク質受容体(Lr7、Lr8、Lrp13)のそれぞれについて、メダカ卵濾胞での発現解析ならびに、KO魚の作出とそれらの表現型解析を進めている。これまでに、Lr8のKOメダカ系統(lr8-KO)の作出に成功し、その表現型解析を行った。その結果、lr8-KO系統メダカの孵化仔魚の生残率が野生型のそれよりも低下することが示された。さらにlr8-KO系統メダカにおいては、4種のVtg(VtgAa1、VtgAa2、VtgAb、VtgC)のうち、VtgAb由来の卵黄タンパク質成分が野生型と比べて相対的に減少しており、Lr8がVtgAbタイプの主要な受容体であることが明らかとなった。

進捗状況を3項目に分けて述べる。
1.不妊魚の作出:ニジマスの卵と凍結保存したブラウントラウトあるいはサクラマスの精子を受精し、第二極体放出阻止処理により作出された雑種三倍体候補(A:ニジマス×ブラウントラウト、B:ニジマス×サクラマス)の倍数性を調査した。その結果、候補Aでは全25個体で、候補Bでは1個体を除く30個体が三倍体であった。これらの個体はPITタグで標識し、現在も継続して飼育している。(藤本)
2.魚卵アレルゲン検知系の構築:引き続き、ニジマス卵アレルゲンであるβ’-component(BC)のペーパー免疫分析デバイスの構築に取り組んだ。デバイスは濾紙にインクを印刷して加熱する常法により作製し、インクで囲まれた領域を分析反応ゾーンとした。分析は、反応ゾーンに新規作製した抗BC抗体を固定化して試料、酵素標識抗BC抗体、発色試薬を順に加えて行う手順とした。本手法では、従来並みの感度(検出感度:約1 ng/mL)の分析が従来の1/100の時間(約20分)で可能となった。(渡慶次、石田)
加えて、交雑種に対応した検知系に使用する抗体の作成のため、サクラマス排卵からBCを精製し、これを家兎に免疫し抗血清を作製した。(平松)
3.不妊化魚の魚卵アレルゲン性の調査:全23個体の不妊化三倍体ニジマスの内臓組織に含まれるBCを測定したが、全個体の筋肉には魚卵アレルギー発症リスクが認められなかった。しかし、5個体において生殖線から少量のBCが検出されたが、その内3個体は目視にて明確な生殖腺の発達が観られた。目視で生殖線の発達が確認できなかった20個体について、生殖腺の組織切片を作製・観察し、その発達状況を確認した。その結果、3個体で発達中の卵母細胞が散在しているのが確認され、生殖腺の外観だけでアレルギー発症リスクの有無を見分けるのは困難であることが判明した。(清水、佐伯、笹岡、平松)

We have previously shown about the mechanisms underlying formation of lipid droplets in teleost oocytes as follows; plasma very low density lipoprotein is the major carrier of neutral lipids to oocyte lipid droplets, and Vldl is metabolized at the outside of oocyte, then free fatty acids derived from the Vldl metabolism are incorporated into oocyte. In this study, we focused on the role of lipoprotein lipase (Lpl), a key enzyme of Vldl metabolism, and analyzed its expression pattern in ovarian follicle using salmonids, medaka, pipefish and zebrafish. As the results, it was suggested that the presence of Lpl expressed in ovarian follicle cells is indispensable for the formation of lipid droplets in oocytes.

This study was undertaken to characterize the hepatoprotective potency of 3,5-dihydroxy-4-methoxybenzyl alcohol (DHMBA), a novel phenolic antioxidant, isolated from the Pacific oyster, using hepatoma-derived cells (C3A) cultured in the presence of pro-oxidant, as well as well-known antioxidants. We found that only DHMBA significantly protected C3A cells against cell death in a dose-dependent manner, whereas other antioxidants did not. Also our study assessed the effects of DHMBA-rich oyster extracts (DOE) in a novel non-alcoholic steatohepatitis (NASH) model mouse established by combination of a high-fat diet and oxidized low-density lipoprotein. The NASH model mouse exhibited obesity, insulin resistance, hepatic steatosis, inflammation, fibrosis, and apoptosis. These changes were significantly moderated by supplementation of DOE. From these results, DHMBA might serve as a functional food for people at elevated risk for ROS-related diseases, such as NASH.

A yolk precursor vitellogenin (Vg) is selectively incorporated from the maternal blood into oocyte following its binding to ovarian Vg receptor. This study demonstrated that Vg obtained from heterologous species, as well as Vg coupled with voluntary lipids, can be delivered to fish eggs and offsprings by injecting them into broodstocks. This indicated a potential use of fish Vg as a transporter of bioactive materials; the system can be universal to any fish species. This study also confirmed that such system was found to be applicable for the delivery of bioactive lipids and/or hydrophobic materials to eggs and offsprings across generations.

In teleost fishes, high amount of lipids and proteins are accumulated in oocytes during their growth phase; they are later utilized as energy and nutrient resources by developing embryos and larvae. However, little is known about the origin of such lipids and the mechanisms underlying their accumulation into oocytes. In the present study, we aimed to clarify the mechanisms at the molecular levels. As the results, we confirmed that, for the first time, plasma very low density lipoprotein is the major carrier of neutral lipid to oocyte lipid droplets, and updated the model for the oocyte lipidation.

本研究は蛍光性物質を親魚から卵・稚仔魚へ輸送する技術の開発を目指し、1)卵母細胞に特異的に発現する2種類の受容体を標的とする抗体の作製、および2)蛍光標識抗体の生体投与試験を行った。実施においては計画した全ての実験を完了した。結果においては、これら抗体によるゼブラフィッシュの卵母細胞や受精卵・孵化仔魚への蛍光物質の輸送は殆ど検出できなかった。一方、本研究と並行した実験により、受容体に対する抗体ではなくリガンドを輸送体に使用した場合、卵母細胞および受精卵・孵化仔魚への蛍光物質の輸送が確認された。以上の結果より、輸送体にはリガンドを使用するべきであり、またその場合、蛍光物質の輸送が技術的に可能であることが示された。

When fish grows ovaries, a yolk precursor vitellogenin (Vg) is incorporated from the blood into oocyte following its binding to ovarian Vg receptor (VgR). This study first identified a portion of VgR-binding region on salmon Vg (sVg) using cutting-edged interactome techniques. Further, a novel C-type Vg (VgC) was cloned and its recombinant protein was synthesized with a limited amount; this provided a basis for discovering the unrevealed VgC receptor.

The objective of this study is to elucidate mechanisms involved in the yolk formation in fish oocytes. Results included development of novel technologies for separation and quantification of multiple subtypes of a yolk precursor (vitellogenin : Vg) ; such techniques were initially developed for the grey mullet, and thereafter applied for several other teleosts. Findings endow the better understandings on fish oogenesis, as well as improvement of fish egg quality in aquaculture and development of technologies for the surveys on the impacts of environmental xenoestrogenic chemicals.

本研究は、魚卵中の卵黄についての研究であり、特に卵黄の素となる血液中の前駆体(ビテロジェニンと超低密度リポ蛋白質)が、どの様に卵へ取り込まれるかを調べた。スズキ類とボラ類の魚を使いこれらの蛋白質や遺伝子を解析した結果、まずビテロジェニンには3種類のサブタイプがあることが明らかとなった。また各種ビテロジェニンと超低密度リポ蛋白質は、それぞれ異なる受容体と結合してから卵の中に取り込まれる可能性が初めて示された。
