Innovative anemia therapy: Development of new anemia drugs targeting the novel mechanism of erythropoiesis

NEXT
PREV
Features

Strong points
Anemia is a very prevalent disease. Nevertheless, an effective therapy is yet to be discovered. Erythropoietin is effective only for those with renal dysfunction. We have found that inhibition of an enzyme for epigenetic regulation results in a prominent increase of erythropoiesis, pointing to a new target for anemia therapy. We have also generated a new, cell-based assay system for the enzymatic activity and carried out small molecule screening.

Collaboration with industry partners
We are seeking a collaboration to accelerate the development of new anemia drugs based on these findings. Together we will advance the development of the candidate molecules currently identified as well as conduct further screening of larger chemical space for better candidates and/or for drug repositioning.

NEXT
PREV
Features

We have much experience on basic studies including experimental animal research on improvement of lipid metabolism and prevention of obesity by functional food components. Causes of obesity and abnormality of lipid metabolism are complex, and measurement of enzyme activity and gene expression does not necessarily give us the precise information on mechanisms of improvement of lipid metabolism and prevention of obesity by food components.

Targeted Application(s)/Industry

Based on our experience, we are prepared to provide academic consultations to companies interested in our research. In some situations, we can conduct effective collaborative research in this field.

Development of the method of Baby Borehole Hydraulic Fracturing, BABHY

Features

For the effective measurement of the reopening pressure in hydraulic fracturing, it is necessary to use the testing equipment with sufficiently small compliance. This limitation makes it difficult to apply the hydraulic fracturing for the measurement of the maximum stress, because the compliance of conventional equipments is generally so large. Taking account of this situation, we proposed a new concept which allows us to do the in-situ tests of hydraulic fracturing for stress measurement at so deep depths as more than 1 km. We call the concept the Baby Borehole Hydrofracturing, BABHY for short. In order to put the new concept into practice, we developed the BABHY sonde and finally we succeeded to carry out hydraulic fracturing test by using the tools in a vertical borehole of 811 m depth. We hope to conduct collaborative research with a willing company for a practical application of this technology in industry.

Generation of Rice Plants Suitable for Biofuel Production

NEXT
PREV
Features

To generate a rice plant suitable for efficient biofuel production from its straw, we examined effects of overexpression of cellulase on saccharification of straw. The transgenic plant constitutively overexpressing cellulase showed enhanced saccharification, but various physiological and morphological abnormalities were also observed. To overcome this problem, a senescence-inducible promoter was used to express the cellulase. The plants successfully avoided the problem and showed enhanced saccharification after senescence.

Targeted Application(s)/Industry

Rice straw will be an efficient material for biofuel production. This method can be applied to other plants. In combination with highly engineered microorganisms for saccharification and fermentation, this method will contribute to efficient production of biofuels.
