Elucidation of oncogenesis by Fbxw7

 
NEXT
PREV
特徴・独自性
  • In life science research field, it is noteworthy issue how information in genome is interpreted and is transferred to functional molecules. However, during these 10 years, we convinced that the amount of proteins, final functional molecules was regulated by not only by production but also by degradation. For examples, the amount of c-Myc, which promotes cell cycle and inhibits cell death, increase in many types of cancer by failure of protein degradation.
  • We have generated model mice in which function of Fbxw7, inducer of c-Myc degradation is suppressed. We observed promotion of oncogenesis in these mice, suggesting that Fbxw7 is oncosuppressor gene. In other words, Fbxw7 has a great potential to regulate oncogenesis or progress of cancer. These molecules specified the target proteins for proteolysis suggesting that modification of these molecules leads to develop oncosuppressive therapy. We hope to conduct collaborative research with a willing company for a practical application of this knowledge in industry.

Synthesis of Biologically Active Cyclodepsipeptide Natural Products

 
NEXT
PREV
特徴・独自性
  • Cyclodepsipeptide natural products include optically active hydroxy acids as well as various unnatural amino acids and exhibit a variety of biological activity depending on the peptide sequence, chirality, and selection of the hydroxy acids. Structure-activity relationships of a synthetic library of natural products could give us significant information of not only biologically important moieties but also intact positions in the biologically active small molecules. On the basis of the former information, more potent compounds and/or peptide mimetics can be designed. The latter information can also be important for making a molecular probe that is used for exploration of a target molecule.

Improvement of Seed Production by Using Reproductive Trait in Crops, Especially, Rice and Cruciferous Crops

 
 
 
NEXT
PREV
概要

The recent spate of extreme weather events is threatening to reduce crop seed and fruit production. We have identified a catalog of genes that respond under low and high temperature stress, and will construct a system that enables production under temperature stress through genome editing and other methods.

従来技術との比較

In addition to conventionally used genetic recombination methods, genome editing technology has made it possible to modify genes that can be used for practical purposes.

特徴・独自性
  • Crops are important for food, environment recovery, energy production, and amenity activity for human being. For improvement of crop seed production, the breeding of crops having environmental stress, is important. Especially the developmental stage from pollination to fertilization is quite weak for these environmental stresses. Thus, by breeding of reproductive trait, we will establish the high productivity and quality of crop seeds. From our research, we found several stress-tolerant genes. We already started the research by both basic and applied level.
実用化イメージ

For application, we evaluated by taking prize for application in 2001. And our basic data has been published in international Journal, "Nature" and "Science". If anyone is interested in these genes, we hope to conduct to collaborative research for establishing the useful breeding lines.

特徴・独自性
  • As modern supercomputers are getting larger and more complicated, it is not so easy to exploit their potential performance. It is necessary to develop a simulation code with considering various factors for both hardware and software reasons, and hence expert knowledge and experiences about supercomputing are often needed to achieve high actual performance. Our research interests focus on shaping future supercomputing systems and their applications, especially system software technologies for effectively using the future supercomputers. Also we are always exploring how to make good use of the state-of-the-art hardware and software technologies in order to enable unprecedented-scale and more advanced simulations.
  • From beginning (apply for use of our supercomputer) to end (get a solution), we can consistently support developing large-scale practical simulation, which is feasible only by using the supercomputer. As a supercomputing center, we have a long history of parallelizing and accelerating a lot of practical simulation programs. In addition, we are looking for research collaborators who are interested in streamlining and/or facilitating large-scale scientific software development.

NEXT
PREV
特徴・独自性
  • This lab is concerned with the novel approach mainly for the growth from melt by studying the relationship between the interface dynamics during growth and properties of grown crystals. Special interests lie in the growth of new crystals via the imposition of an interface-electric field. Nano-scaled control of crystal growth is executed in an electric double layer of ~nm thickness that is induced by applying an external electric field on the growth interface. Some of our growth results brought by applying an electric field are;

Novel high-throughput screening systems for new antibiotics targeting bacterial virulence factors

 
 
 
NEXT
PREV
特徴・独自性
  • Chemotherapy toward bacterial infection, which dates back to the discovery of penicillin, opened up the golden era of antibiotics. Thereafter, various clinically important antibiotics were introduced into the clinic, and hence serious bacterial infectious diseases were eradicated. However, this ephemeral hope has been disappearing due to the emergence of antibiotic resistant pathogens toward every new antibiotics launched into the clinic, such as multidrug-resistant Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus (MRSA). To combat these life-threatening pathogens, there is a pressing need to develop new antibiotics. However, new antibiotics discovered in the future will be nullified by development of resistance to these antibiotics, since their targets are essential for bacterial survival. From this aspect in which inhibitors of the essential functions inevitably select resistant mutants, bacterial virulence could be a fascinating target for developing new antibiotics, because virulence attenuators are thought to be less likely to generate resistance. We focus on a novel protein translocation system, Tat, since this system appears to be involved in several aspects of bacterial virulence and is not present in mammalian cells, and iron-metabolism-associated system as novel targets for development of their inhibitors. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.

Universal Design in Language Use

 
 
NEXT
PREV
概要

My current research topic is "universal design in language use," with special reference to order in language and thought. In particular, I am investigating (1) similarities and differences in neural processing of languages with different basic word orders, (2) to what extent the order in non-verbal thought is affected by the order in language, and vice versa, and (3) what is the optimal order in human language and human thought, if any.

従来技術との比較

Many studies have reported that subject-object (SO) word order, where the subject (S) precedes the object (O), tends to have lower processing costs and is preferred by native speakers compared to object-subject (OS) word order. However, traditional studies have primarily focused on SO languages, such as Japanese and English, where SO word order is the grammatical default. As a result, it remains unclear whether the preference for SO word order reflects the basic word order of individual languages or more universal cognitive characteristics of humans.

特徴・独自性
  • To address this, we are conducting research on the cognitive processing of minority languages that use object-subject (OS) word order as their basic word order—specifically Kaqchikel and Truku, which have not been studied before. This research focuses on the relationship between “word order in language” and “order of thought.” The findings are then compared to the cognitive processing of Japanese and English.
  • For this purpose, experimental equipment is brought to the speakers’ regions (Guatemala and Taiwan) to conduct a variety of investigations and experiments, including behavioral experiments, eye-tracking, and brain function measurements. Additionally, for experiments requiring large, non-portable equipment such as MRI scanners, the speakers are invited to Japan for the studies.
実用化イメージ

Although I am conducting basic research, I believe it helps develop (1) effective language teaching/learning methods, (2) rehabilitation programs for aphasia, (3) dynamic preservation of endangered languages/dialects, and so on.
