Head and neck cancer, Malignant mesothelioma, TGF-β signal transduction, CTGF, Head and neck mucosal melanoma, Molecular target therapy, Translational research, Bioinformatics

【Recent highlights】
The field of genomic medicine has experienced rapid progression since the completion of the Human Genome Project in 2003. Many diseases have been shown to derive from genomic abnormalities, and research based on the knowledge of human genome is predicted to lead to new insights in advancing our understanding of human disease. 
Currently, one in two individuals dies from cancer in Japan, whereas outcomes with cancer treatments have improved due to remarkable progress in technology. New diagnostic techniques and therapeutic approaches are developed based on global research in genomic medicine and tumor biology. 
The long-term effort of researchers around the globe has led to the development of many successful therapies for patients with cancer, and more innovations in cancer treatment are expected in future.

【Research】
Our laboratory is dedicated to elucidating the molecular mechanisms underlying refractory tumors such as malignant mesothelioma and mucosal melanoma, and to identifying novel therapeutic targets. In malignant mesothelioma, abnormalities in the NF2 (neurofibromatosis type 2) gene and its downstream Hippo signaling pathway are known to enhance the expression of CTGF (Connective Tissue Growth Factor) in cooperation with TGF-β (Transforming Growth Factor-β), thereby promoting tumor growth. 
Moreover, we have discovered a novel regulatory mechanism in which the PDGFR–AKT signaling axis increases CTGF protein levels through translational control, independent of changes in mRNA abundance. We are currently working toward the development of therapeutic strategies targeting both the TGF-β–CTGF and PDGFR–AKT–CTGF pathways. 
We are also engaged in bioinformatics analyses using RNA-seq and genomic data to identify biomarkers associated with tumor aggressiveness and patient prognosis, as well as to explore potential therapeutic targets. 
By integrating cellular and molecular biology approaches with computational science, and through active interdisciplinary collaborations, we aim to contribute to the development of innovative treatment strategies for refractory cancers.
