21st June 2018
Dr Takayuki Koyano gave a talk in 30th HiHA seminar. The title was “腎臓病の病態解明に向けた分子遺伝学的解析―ゲノム編集技術を利用したモデル動物作製から解析まで―”.
Dr Koyano graduated from Department of Molecular Biotechnology Graduate School of Advanced Sciences of Matter, Hiroshima University and obtained PhD. After that, he joined Takashi Toda’s laboratory at the Francis Crick Institute and spent for two years in London (2013-2015). Then he got a research scientist job in Shigei Medical Research Institute (重井医学研究所) in Okayama, Japan.
13th June 2018
Takashi Toda and Masashi Yukawa visited Professor Wataru Yasui (安井 弥教授, on the left in the photo) and Associate Professor Naohide Oue (大上直秀准教授, on the right) in Department of Molecular Pathology, Institute of Biomedical & Health Science, Hiroshima University, and discussed potential collaborative research on human kinesin molecules and their inhibitors. Professor Yasui’s group has found that several kinesin genes including KifC1/HSET are specifically upregulated in many cancer stem cells including gastric, oesophageal and colorectal cancers. They have further shown that knockdown of these kinesin genes kill various cancer cells. Takashi Toda’s group has been working on kinesins in fission yeast and recently shown that KifC1/HSET is functional in fission yeast. Furthermore, they have been developing novel inhibitors specific to human kinesin.
6th and 7th Jun 2018
Takashi Toda attended Joint Annual Meeting of 51st JSDB (Japanese Society of Developmental Biology) and 70th JSCB (Japan Society for Cell Biology) held in Tokyo, and gave an oral talk and also did a poster presentation.

After staying for more than 4 months in our laboratory, Corinne Pinder has completed postdoctoral work and returned to UK. Thank you very much. We wish Corinne the best of luck.
Takashi Toda attended the 21st board meeting of Japan Microbiology Association held at the Science Council of Japan in Tokyo. The reason for this attendance was to establish and strength the domestic research network between the HiHA and microbiologists/medical researchers to promote collaborative programmes.
Annual get-gather party for regional yeast researchers was held on 14th April at National Research Institute of Brewing within the science park in HIgashi-Hiroshima. This year the party was organised by Professor Akinori Matsushika at National Institute of Advanced Industrial Science(AIST). Approximately 60 yeast researchers working in the HIgashi-Hiroshima area attended. From our group, five members (Takashi Toda, Masashi Yukawa, Mitsuki Ohishi, Ryo Murayama and Satoshi Muto) attended and enjoyed talking to attendants and drinking sake.
A new paper was published from Takashi Toda and Masashi Yukawa group. This work was achieved through international collaborations performed by three research teams in Hiroshima University (Toda and Yukawa), Iwate University (Ken-ichi Kimura) and CSIR-Central Drug Research Institute in India (Shakil Ahmed). The research was in part supported by a JSPS grant “Fostering international researchers through the collaborative research network focusing on the mechanisms of lifespan regulation ”.
