PathologyTumor Pathology/Molecular Pathology


Our department is responsible for education of pathology for medical students and is pursuing research in cancer and neurological disease. Our major research interests include (1) Roles of the RET proto-oncogene in cancer development and organogenesis, (2) Molecular mechanisms of cell motility mediated by Akt signaling and Girdin family proteins, (3) Roles of CD109 in cancer progression and (4) Roles of Meflin (ISLR), a newly identified marker for mesenchymal stem cells, in pathological fibrosis and cancer microenvironment.

Research Projects

(1) Roles of the RET proto-oncogene in cancer development and organogenesis
  The RET oncogene was identified by transfection of NIH3T3 cells (Takahashi et al. Cell 1985). The RET proto-oncogene encodes a receptor tyrosine kinase whose expression is detected in the nervous system and the embryonic urogenital system. Mutations in RET are responsible for the development of papillary thyroid cancer, lung adenocarcinoma, multiple endocrine neoplasia type 2 and Hirschsprung disease (Takahashi, Cytokine Growth Factor Rev, 2001). Our group has been studying the molecular mechanisms of these diseases caused by RET mutations.
  RET is activated by glial cell line-derived neurotrophic factor (GDNF) which binds to GDNF family receptor ??(Treanor et al, Nature 1996)??GDNF-GFR?-RET signaling is essential for the development of the enteric nervous system, renal organogenesis and spermatogenesis. Using several Ret mutant mice, we are studying the roles of RET signaling in organogenesis.

(2) Molecular mechanisms of cell motility mediated by Akt signaling and Girdin family proteins
  It is known that Akt signaling plays an important role in the motility of various types of cells. We identified a new Akt substrate and an actin-binding protein Girdin using an yeast two-hybrid screening (Enomoto et al. Dev Cell 2005). In response to growth factor stimulation, Girdin is phosphorylated at serine 1416 by Akt and accumulated at the leading edge of migrating cells. When Girdin expression is knock-downed by siRNA, lamellipodia formation at the leading edge is largely impaired, resulting in the decrease of cell migration. Actually, Girdin is necessary for the motility of cancer cells, endothelial cells and neuronal cells. Girdin KO mice showed the impaired vascular development in the retina and brain, the impaired chain migration of neuroblasts in rostral migratory stream and the abnormal architecture in the dentate gyrus (Kitamura et al, Nat Cell Biol, 2008; Jiang et al, Cancer Res, 2008; Enomoto et al, Neuron 2009; Wang et al, J Neurosci, 2011). Our group is studying the precise mechanisms of cell motility via Girdin function, particularly about how Girdin regulates the actin reorganization at lamellipodia.

(3) Roles of CD109 in cancer progression
  CD109 is a glycosylphosphatidylinositol-anchored cell surface protein. We identified CD109 as a protein induced by activation of RET tyrosine kinase. CD109 expression was detected in various cancer cells including squamous cell carcinoma, glioblastoma and adenocarcinoma (Hashimoto et al, Oncogene, 2004). Using CD109-deficient mice, we showed that CD109 expression promotes tumor growth and progression (Sunagawa et al, Oncotarget, 2016; Shiraki et al, J Pathol, 2017). In particular, CD109 was highly expressed in brain tumor stem cells (BTSC) in the perivascular region, suggesting that CD109 becomes a potential target for cancer therapy. We are now developing monoclonal antibodies against CD109 and investigating their efficacy on cancer therapy.
  CD109 is known to negatively regulate TGF-??signaling (Hagiwara et al, Oncogene, 2010) and positively regulate EGF signaling (Zhang et al, BBRC, 2015). It is also our interest to study the mechanisms on how CD109 regulates these signaling pathways and its biological significance.

(4) Roles of Meflin (ISLR), a newly identified marker for mesenchymal stem cells (MSC), in pathological fibrosis and cancer microenvironment.
  Like CD109, Meflin, which is encoded by ISLR gene, is a glycosylphosphatidylinositol-anchored cell surface protein. Meflin is expressed in cultured MSCs as well as stromal cells throughout the bone marrow, pericytes and perivascular cells in multiple organs but not other types of cells. Meflin maintains the undifferentiated state of cultured MSCs and is downregulated upon their differentiation (Maeda et al, Sci Rep, 2016). Thus, we suppose that Meflin is a new useful marker for MSCs. In addition, we recently found that a portion of cancer-associated fibroblasts (CAF) expressed Meflin. Interestingly, Meflin-high CAF and ?low CAF are ?SMA-low and ?high CAF, respectively. The aim of this project is to elucidate the functional difference of Meflin-high or ?low fibroblasts in cancer microenvironment and in pathological fibrosis.
