Molecular Imaging of Transplanted Stem Cells Derived from Original NIS Transgenic Mouse
Grant number：26293282 2014.4 - 2018.3
INUBUSHI Masayuki
Authorship：Coinvestigator(s)
Using a transgenic mouse systemically and stabley expressing NIS genes (NIS-Tg mouse), we collaborated on the following 3 studies with specialists. (1) We succeeded in changing over its breeding from hetero-crossing to homo-crossing that increases possibility for higher gene expression, and almost established its inbred line (Kawasaki Med School). (2) We succeeded in in-vivo quantitative analysis of the function of stem-cell sheets made with stem cells derived from the NIS-Tg mouse, which contributed to the development of a novel iPS-sheet therapy for myocardial infarction in humans (NCVC). (3) We performed transplantation of stem cells derived from the NIS-Tg mouse to irradiated mice, and investigated how and with which specific character of stem cells the mice could be survived after high-dose radiation exposure (NIRS).

Development of hereditary non-polyposis colon cancer model using the Mlh1-deficient heterozygous mice
Grant number：22501002 2010 - 2012
KAKINUMA Shizuko
Authorship：Collaborating Investigator(s) (not designated on Grant-in-Aid)
Heterozygous germline mutations of mismatch repair (MMR) genes cause human hereditary non-polyposis colon cancer, and homozygous mutations are manifested by early onset of childhood T- or B-cell leukemia. In order to develop models for both colon cancer and lymphoma, we examined induction protocols with radiation and an inflammatory agent in Mlh1-/- homozygous and Mlh1+/- heterozygous mice. The protocols we established reproducibly induced colon cancer in Mlh1-/- homozygous and Mlh1+/- heterozygous mice, and lymphoma in Mlh1-/- homozygous mice using radiation and/or an inflammatory agent.

精子形成期の半数体特異的遺伝子発現を利用した単性動物の作出
Grant number：21658094 2009 - 2010

本研究においては、雌雄の産み分けが可能な雄を作出する目的で、22年度は下記の2点について検討を行った。
(1) 導入遺伝子産物であるmRNAおよび翻訳後のタンパク質が精子形成期の細胞間架橋を自由に通過できないような仕組みを開発する。
(2) 遺伝子導入された染色体を持つ精子が受精できない仕組みを開発する。
(1)についてはSmok1遺伝子の5'および3'非翻訳領域が細胞間架橋に関与することが明らかになったが、その正確な遺伝子配列は公表されていない。そこで、それぞれの配列のクローニングを行い、実際にゲノム上およびcDNA中にその配列が存在することを確認し、遺伝子組換えマウス作製のための組換えベクターを作出した。(2)については精子アクロソーム膜上に発現し、受精に関与することが示唆されているタンパク質をコードする遺伝子にRSK3遺伝子の3'UTRを接続した融合遺伝子を構築し、この遺伝子をプロタミン制御下で発現する遺伝子組換えマウスを作製した。作出したマウスのF1個体を使って、受精に及ぼす影響および細胞間架橋の通過について検討した。いくつかの系統では正常に産子が得られたため、受精には影響していないと考えられたが、不妊傾向が認められる系統も得られており、現在解析を行っている。 -
Analysis of oocyte-specific gene, Oog1 and its involvement in molecular basis of zygotic gene activation
Grant number：19380158 2007 - 2009
MINAMI Naojiro
Authorship：Coinvestigator(s)
In the present study, we investigated the function of oocyte-specific gene, Oog1. The gene translocates to the nucleus of fertilized embryos at the time of zygotic gene activation. In order to analyze the function of the gene, we produced the transgenic mice in which the mRNA of Oog1 is knockdown. In addition, we investigated the protein expression of Oog1 during female meiosis and it is revealed that the protein exists in the oocyte nucleus at the prophase of meiosis. In another experiments, we identified the regulatory regions of Oog1 which controls the expression of the gene.

Development of the gene deletion model rats by random mutagenesis.
Grant number：16500282 2004 - 2005

Random mutagenesis with chlorambucil was performed in order to produce some new mutant rats. To identify the optimal quantity of chlorambucil and the optimal mating time for mutagenesis, we counted the number of new born rats born from female rats mated with the male rat medicated with several dose of chlorambucil. Consequently, it became clear that between 2.5mg and 15mg per kg weight of chlorambucil are good for medication, and it is good to perform mating between three weeks and six weeks after the medication of chlorambucil. We obtained several dwarfish rats from BN and F344 strans. Dwarfish rats whose sizes of the body were about 30% of normal rats were also observed. We also obtained a mutant rat with fiblosarcoma from the BN strain. This fiblosarcoma has grown up to 5cm or more in the diameter within 2 weeks. Unfortunately, we have not determined the genome region of delition of this rat by quontitative PCR analysis. Future experiments will focus on searching this genome region of delition by microarray or BAC array analyses.
