Research Interests In human body, a lot of cells (especially epithelial cells and blood cells) are always replaced into newly synthesized ones. Precise cell proliferation control is of great importance for human health because cell-cycle control is often dysregulated not only in carcinogenesis but also aging process. Our research goal is to investigate mechanisms by which several protein kinases precisely regulates cell proliferation. We are also studying how the disorders of these kinases lead to cancer or aging. Furthermore, we try to develop new in vivo imaging system to detect cancer cells or senescent cells (which semi-permanently arrest cell proliferation).

Research Interests Excitatory and inhibitory neurotransmitter receptors usually form protein complex by various combinations with subunits and express their spatio-temporal function. Among them, AMPA type glutamate receptors (AMPA-Rs) are supposed to be central molecule for hippocampal memory formation. We have developed an optical technology for acute inactivation of synaptic GluA1 homomeric receptors in vivo by chromophore assisted light inactivation, CALI (Takemoto et al. Nat. Biotechnol. 2017). This technology enabled us to elucidate the function of GluA1 homomer in the acquisition of contextual fear memory in hippocampus. By combination of these CALI methods with two photon microscopy, we now focus on elucidating the molecular mechanisms of hippocampal memory acquisition and retention by spatio-temporal manner in vivo.

Research Interests Stem cells are defined as cells that are capable of self-renewal and differentiation to specialized cell types. Our laboratory is investigating on the ontogeny and the fate determination of stem cells, and how these stem cells contribute to the development of tissues or specific system. Currently, our research focuses are on development of neural crest-derived tissues and hematolymphoid system. The following projects are underway:

1) Research on lineage commitment and differentiation from pluripotent stem cells using in vitro culture of mouse embryonic stem cells.
2) Research on organogenesis of thymus, bone marrow, and tooth tissues focusing on the contributions of neural crest stem cells and neural crest-derived cells.
3) Research on development of hematopoietic stem cells
4) Research on development of immune system

The above projects involved the techniques of animal experiments, cell and tissue culture, and cell and molecular biology. The aim of the course is to master these basic techniques and to obtain scientific thinking skills required in the fields of developmental biology, stem cell biology, and immunology.

Staff Kyoko YOSHIDA, MD, PhD, Professor
Research Interests We are studying molecular mechanisms on
(1)Embryogenesis and organogenesis.
(2)Tissue remodeling in pathological conditions including cancer, inflammation and regeneration.
During these conditions, reciprocal communication between parenchymal and stromal cells regulates cell proliferation, migration and differentiation, which leads to construction of a new tissue architecture. Tissue remodeling processes is essential for repair of the damaged tissues, but sometimes results in unfavorable outcomes such as fibrosis. We are studying intercellular signaling mediated by cytokines, and synthesis and degradation of extracellular matrix proteins. Our research goals are to intervene in the remodeling processes and to lead to favorable results. Furthermore, diagnostic applications of the related molecules are also studied.

Research Interests We are studying molecular and pathological mechanisms on
(1)Prostate cancer biology.
(2)Tumor microenvironment.
Prostate cancer is initially sensitive for anti-androgen hormone therapy. But most of the prostate cancers change to hormone refractory that could be a cause of death. One of our research goals is restoration of hormone refractory cancer to sensitive cancer.
Tumors are composed with cancer cell, stromal cells, such as fibroblast microvessels, inflammatory cells. Those cells communicate in reciprocal manner and overall promote tumorigenesis. We are also studying the cancer and stromal interaction.

Research Interests Many drugs have been developed to prevent and/or treat diseases. There are still many unresolved issues, however, in the development of therapeutics and understanding the mechanisms. To tackle these problems, we take integrative approaches using different types of omics datasets, bioinformatics tools, and model animals. The aim of our research is to find new relationships between diseases and drugs through the integrative pharmacological approaches.

Department Molecular Pathobiology
Staff Motomu Shimaoka, MD, PhD, Professor
Eun Jeong Park, PhD, Associate Professor
Research Interests We study roles of integrins in immune cells, cancers, and their Exosomes Integrins represent the largest family of cell adhesion molecules that mediate cell-to-cell, cell-to-extracellular matrix, and cell-to-pathogen interactions in a wide range of physiology and pathophysiology such as inflammation and immunity, host defense and cancer progression and metastasis, and vascular integrity and thrombosis. Integrins are composed of the alpha and beta subunits that non-covalently associate each other, thereby forming the alpha/beta heterodimeric membrane receptors. Integrins regulate leukocyte-endothelial cell interactions, thereby playing the pivotal roles in the pathogenesis of inflammatory tissue damages. Our laboratory has studied the roles of integrins in health and diseases as well as cells and exosomes using the state-of-the-arts technologies such as CRISPR/Cas9 gene-editing, Nanoparticle Tracking, Protein Engineering, and novel disease models.

We have a team of internationally diverse faculty members and students. All communications in meeting rooms and on the bench are English, thereby providing a friendly environment for international students who wish to study biomedical science in Japan.

Research Interests Animal Functional Genomics Lab is interested in the genetic events that contribute to the development of cancer. Current focus of our research has been a series of mouse strains engineered to carry mutant genes, oncogenic K-, N-, H-rasG12V and dominant negative Bone morphogenetic protein (BMP) receptor type 1A (BMPR1A) genes, known to be involved in human cancer. We have established several mouse lines by gene targeting to create more powerful and accurate mouse models of human cancer and tried to explore the pathways regulated by cancer-associated genes. We have generated mouse models of several human cancer types, including lung cancer, peripheral nervous system tumors, rhabdomyosarcoma and a mouse model of cancer cachexia. These models give us cutting-edge tools in genetics, genomics, and imaging, as well as with various chemotherapeutic agents.

Research Interests To tolerate external force, to sustain cell shape and to perform cell division, cells require cytoskeleton, such as intermediate filament, microtubule and actin filament. Therefore, dysfunction of component proteins forming cytoskeleton leads to many kinds of disease.
We have defined the role of phosphorylation of intermediate filaments. Disruption of intermediate filament phosphorylation induced aneuploidy as a result of abnormality of cell division.
In addition, we have clarified that primary cilia, a microtubule-based sensory organelle, regulates cell cycle using gene silencing method.
Now, we are exploring 2 specific points; (1) A role of phosphorylation of intermediate filaments using transgenic mice; (2) Regulation of cell cycle by ciliogenesis.
